HYPOTHYROIDISM 101

Thyroid hormone tells all of the cells in your body how busy they should be. Too much thyroid hormone (hypERthyroidism), and your body goes into overdrive; not enough thyroid hormone (hypOthyroidism), and your body slows down.  The most common causes of hypothyroidism worldwide are dietary—protein malnutrition and iodine deficiency.  This is because the two main ingredients needed to make thyroid hormone are tyrosine (an amino acid from dietary protein) and iodine (a naturally-occurring salt).

In the developed world, where protein is plentiful and many countries add iodine to salt and processed foods, we don’t typically need to worry about protein malnutrition or iodine deficiency.  However, the rest of the world is not so lucky. More than 2 billion people around the world suffer from hypothyroidism due to iodine deficiency.  2 billion!  We are told that the reason for this planetary epidemic is that iodine comes from the ocean, and that the soil of inland areas has had most of its iodine washed away over time by erosion:

“A teaspoon of iodine is all a person requires in a lifetime, but because iodine cannot be stored for long periods by the body, tiny amounts are needed regularly. In areas of endemic iodine deficiency, where soil and therefore crops and grazing animals do not provide sufficient dietary iodine to the populace, food fortification and supplementation have proven highly successful and sustainable interventions.” [Brahmbhatt 2001].

But the iodine erosion explanation does not make sense to me, and here’s why.SodaStream (Soda-Club) USA

Iodine is an essential ingredient in thyroid hormone, and thyroid hormone is critical to the growth and development of the bodies and brains of all baby vertebrates (animals with backbones).  Since they need iodine just as much as we do, and they do not have access to artificially iodized salt, how do they get their iodine?  Do they have a secret stash somewhere that they’re not sharing with us? I assume they are getting enough iodine because if they weren’t, they would all be born brain-damaged runts, and many would be infertile if they survived to adulthood.  To the best of my knowledge, wild inland animals are not herds of sterile, stupefied miniatures roaming the landscape in search of iodine…

IODINE REQUIREMENTS

We are told that humans need an average of about 150 micrograms of iodine per day.  Below is the iodine content of some familiar foods [in micrograms]:

  • Cod Fish (3 ounces) = 99
  • Shrimp (3 ounces) = 35
  • Turkey (3 ounces) = 34
  • Low-fat milk (1 cup) = 56
  • Egg (1 large) = 24
  • Prunes (5 whole) = 13
  • Banana (1 whole) = 3

When you look at this list, it is easy to imagine how it might be difficult to obtain 150 micrograms per day of iodine, depending on what you eat.  This is why we are told we should use iodized salt, which contains 142 micrograms of added iodide per ½ teaspoon:

“More than 70 countries, including the United States and Canada, have salt iodization programs. As a result, approximately 70% of households worldwide use iodized salt, ranging from almost 90% of households in North and South America to less than 50% in Europe and the Eastern Mediterranean regions.  In the United States, salt manufacturers have been adding iodine to table salt since the 1920s, although it is still a voluntary program.”  [http://ods.od.nih.gov/factsheets/Iodine-HealthProfessional/#h3]

salt shaker

I suspect that there is actually enough iodine in the environment to go around, and that we actually need less than 150 micrograms per day of iodine.  From the above list, you can see that animal foods are much richer in iodine than plant foods—so how do herbivores (animals which eat a plant-based diet, such as rabbits and deer) get enough iodine?  I suspect that there is something about the human diet which interferes with our ability to absorb, utilize, and/or retain iodine, and that this is why we appear to be iodine-deficient compared to other animals.  So, what might the possible culprits be?   Hmmm….

PLANT GOITROGENS

When in doubt, blame plants.  Yes, plant foods, once again, are the usual suspects (to read more about why plants are untrustworthy when it comes to human health, see my vegetables page).  Many plant foods contain naturally-occurring chemicals which disrupt normal thyroid function.

The main job of the thyroid gland is to combine the salt iodine with the amino acid tyrosine to make thyroid hormone.  Whenever the thyroid gland has a hard time making enough thyroid hormone, it becomes stressed and grows bigger to try to do its job better, forming a “goiter” (enlarged thyroid).  Substances that interfere with normal thyroid function are called “goitrogens” because they have the potential to cause goiter.

GOITRIN

Goitrin is the most powerful plant goitrogen.  Unlike most other goitrogens, this chemical can cause goiter even if there is plenty of iodine in the diet.

Goitrin weakens the activity of the enzyme thyroid peroxidase, which is required to insert iodine into thyroid hormone.

Foods containing goitrin:

  • Seeds of Cruciferous Vegetables
  • Rutabaga (aka Swede, Yellow Turnip)

rutabaga

THIOCYANATES

Thiocyanates are sulfur-containing compounds found in a variety of popular vegetables.

Thiocyanates make it harder for the thyroid gland to absorb iodine because they compete with iodine for entry into the gland.  This effect can be minimized by supplementing the diet with iodine; the excess iodine can then crowd out the thiocyanate and win the competition.

Thiocyanates weaken the activity of the enzyme thyroid peroxidase, which is required to insert iodine into thyroid hormone.  This effect can be greatly reduced by iodine supplementation.

Foods that form thiocyanates:

  • Bamboo Shoots
  • Cassava*
  • Corn
  • Flax
  • Lima Beans
  • Sweet Potato
  • Cruciferous Vegetables:
    • Arugula
    • Bok choy
    • Broccoli
    • Broccolini
    • Brussels sprouts
    • Cabbage
    • Canola
    • Cauliflower
    • Chinese Broccoli
    • Chinese cabbage
    • Choy sum
    • Collard greens
    • Horseradish
    • Kale
    • Kohlrabi
    • Mizuna
    • Mustard Greens
    • Mustard Seeds
    • Radishes
    • Rapini
    • Rutabagas
    • Turnips
    • Wasabi
    • Watercress

cruciferous vegetables

The foods listed above do not contain any thiocyanate when they are in their living, intact state, because thiocyanates do not form until the plant is cut, crushed, or chewed.   For example, fresh broccoli contains a harmless substance called glucosinolate, which turns into a thiocyanate called sulforaphane when the vegetable is damaged (see my broccoli blogpost for more information).
*Cassava bears special mention here.  You may have heard of it because it is the starchy root vegetable from which tapioca is made, but cassava is also a popular staple food in many Third World countries, where it is eaten boiled, mashed, or ground into flour.  Fresh cassava root contains a harmless substance called linamarin, which can turn into hydrocyanic acid (aka cyanide!) when the plant is damaged or eaten. Flaxseeds also contain linamarin. Cyanide is very toxic, so the human body converts it into thiocyanate (which, although it does interfere with thyroid function, is less toxic than cyanide and easier for the body to eliminate).

cassava

Thiocyanates easily cross the placenta and can cause thyroid dysfunction in newborns, especially if the infant is not getting enough iodine.

Cooking, soaking, and fermentation can reduce cyanide and thiocyanate levels in these foods.

FLAVONOIDS 

Flavonoids are a large family of related plant compounds; at least 3,000 different flavonoids have been discovered thus far, but we will concentrate on those that are especially risky when it comes to thyroid health.

Soy Flavonoids (genistein, daidzein) 

Soy flavonoids are perhaps better known as “soy isoflavones”, which we are usually told are good for us.  Yet, 

“It is well described but little known that the soybean and goiter have long been associated in animals and humans.” [Doerge] 

Soy

Soy flavonoids reduce the activity of thyroid peroxidase, the enzyme required to insert iodine into thyroid hormone.

Cooking does not destroy the goitrogenic activity of soy isoflavones.

There is strong clinical evidence demonstrating the anti-thyroid effects of soy products on infants, children, and adults.

“Infants fed soy formula are at higher risk for hypothyroidism and for later development of autoimmune thyroid diseases. In humans, goiter has been seen in infants fed soy formula; this is usually reversed by changing to cow milk or iodine-supplemented diets . After the 1960s, manufacturers reportedly began adding iodine to formulas to mitigate thyroid effects.” [Doerge]

When a baby is born with hypothyroidism, thyroid hormone supplements are administered to correct the deficiency.  Babies fed soy formula require 25% higher doses of thyroid hormone than babies fed soy-free formula.  [Xiao]  For this reason, doctors recommend that children with hypothyroidism avoid soy products if at all possible. 

In adults, the recommendations are stated more softly, perhaps because of the widespread belief that soy is good for us, or because some people prefer to eat soy instead of meat:

“Some evidence suggests that soy foods, by inhibiting absorption, may increase the dose of thyroid hormone required by hypothyroid patients. However, hypothyroid adults need not avoid soy foods. In addition, there remains a theoretical concern based on in vitro and animal data that in individuals with compromised thyroid function and/or whose iodine intake is marginal, soy foods may increase risk of developing clinical hypothyroidism. Therefore, it is important for soy food consumers to make sure their intake of iodine is adequate.” [Messina]

Note that the recommendation for adults is to increase iodine intake rather than to decrease soy intake. But take a look at this interesting clinical study [Sathyaplan]:

60 patients with borderline hypothyroidism were given either 2 mg of soy isoflavones (the amount found in the typical omnivore’s diet) or 16 mg of soy isoflavones (the amount found in the typical vegetarian’s diet).  The “vegetarian” dose of soy isoflavones was 3 times more likely to cause patients to convert from borderline (“subclinical”) hypothyroidism to full-blown (“overt clinical”) hypothyroidism.

In my experience, most people are unaware of the connection between soy and thyroid problems.  If a study like this had been about an ingredient in red meat, you can bet you’d see a giant headline in the New York Times trumpeting that red meat causes thyroid disease, and everyone would be talking about it…

Millet Flavonoids (apigenin, glucosylorientine, vitexin) 

Millet is most familiar to us in the developed world as birdseed, but it is also a common staple grain eaten by people in developing countries, because it grows well in hot places with poor quality soil.

millet

Millet flavonoids greatly reduce the activity of thyroid peroxidase, the enzyme that inserts iodine into thyroid hormone.  Apigenin is the most potent of the three listed above.

Millet flavonoids also (quite rudely) push thyroid hormone off of carrier proteins in the bloodstream.

Cooking does not destroy millet flavonoids.

In the Darfur Province of western Sudan, goiter in schoolchildren is closely linked to millet consumption:

“…goiter is more prevalent in rural villages of the Darfur Province in Sudan, where as much as 74% of dietary energy is derived from millet, than in an urban area, where millet provides only 37% of calories, even though the degree of iodine deficiency is similar in the two areas.” [Gaitan]

Other foods containing apigenin include:

  • Chamomile
  • Citrus fruits
  • Parsley
  • Onions
  • Wheat sprouts
  • Red wine
  • Beer

QUERCETIN and friends

Quercetin and its relatives work in two ways to interfere with thyroid hormone metabolism.

1.  Reduce activity of thyroperoxidase, the enzyme required to insert iodine into thyroid hormone.

2.  Reduce activity of hepatic deiodinase, a liver enzyme required to activate thyroid hormone.

Quercetin—found in significant amounts in capers, cranberries, onions, tea, broccoli, red wine, black currants, apples, grapes, blueberries, gingko biloba, and apricots.

Kaempferol—found in significant amounts in tea, capers, grapefruit, and endive.  Kaempferol is closely related to quercetin and even more easily absorbed.

Rutin—found in significant amounts in buckwheat, asparagus, citrus fruits, cranberries.  Rutin is also a close relative of quercetin, but less well absorbed.

Boiling destroys up to 30% of the quercetin, kaempferol and rutin in food.
SodaStream (Soda-Club) USA

Can you eat too much iodine? 

Yes.  The safe upper limit of iodine intake is considered to be 1,100 micrograms (1.1 mg) per day.  Since 1 teaspoon of iodized salt contains 284 micrograms of iodine, if you eat 4 teaspoons of iodized salt in a day, you have already exceeded the safe amount.

Strange as it may seem, hypothyroidism can be caused both by too much iodine and by too little iodine. Excess iodine interferes with the release of thyroid hormone into the bloodstream and can cause goiter and hypothyroidism.

“Excess iodine is generally well tolerated, but individuals with underlying thyroid disease or other risk factors may be susceptible to iodine-induced thyroid dysfunction following acute or chronic exposure. Sources of increased iodine exposure include the global public health efforts of iodine supplementation, the escalating use of iodinated contrast radiologic studies, amiodarone administration in vulnerable patients [amiodarone is a drug used to treat heart rhythm problems], excess seaweed consumption, and various miscellaneous sources.”  [Leung]

The foods most commonly associated with excess iodine are seaweed and iodized salt.  A single gram (0.035 ounce) of seaweed can contain anywhere between 16 and 2,984 micrograms of iodine!

seaweed

In addition to containing high amounts of iodine, seaweeds in the Laminaria family (kelp family) contain phloroglucinol and other polyhydroxyphenols, which are potent anti-thyroid compounds themselves.

Dietary Recommendations for Hypothyroidism

If you have hypothyroidism, or want to reduce your risk for hypothyroidism, you may want to consider the following strategies:

  1. Eliminate the most potent goitrogens from your diet (soy, millet, and rutabaga).
  2. Minimize or at least thoroughly cook all other goitrogenic foods listed in this article, such as cruciferous vegetables and sweet potatoes.
  3. If you choose to include significant amounts of goitrogenic foods in your diet, be sure to consume 150 micrograms per day of iodine.
  4. Be careful not to consume too much iodized salt or seaweed.

    Amounts vary among sources (1-13mg/day) but most agree that iodine intake among the Japanese universally exceeds what’s considered safe in the Western mainstream medicine. The Japanese don’t seem to suffer any ill effects. Why? Is there some synergistic mechanism at play here? Or are they just good at excreting excess dietary iodine?
    Thanks for the comprehensive post 🙂

    • Hi Ruby
      Great question–the quote from the Leung article suggests that most people are able to tolerate excess iodine, but doesn’t explain why. I have just requested an article from the library that should help to clarify the issue. Once it’s arrived I’ll post what I hope will be a better answer…

      • Jenny

        Or maybe they NEED the extra iodine because most oriental vegetables belong to the crucifer family….

          HI, No gluten/dairy/soy/sugar/GMO and vitamins/good oils, LDN and detoxing help me. Vit D3 5000IU, zinc 50mg, fish oil 2000mg, 20000mg of evening primrose oil. 2000mg of lecithin, krill oil, coenzyme Q10, rhodiola, Mg citrate 4000mg, Vit C, 5000mcg of biotin, Nature’s Plus- Source of life multiple, HCl and enzymes with meals, dairy free probiotic, Vit B12 methylcobalamin shot/spray/under the tongue kind/intrinsic factor kind, MTHF folate, coenyzme Q10, rhodiola, may help brain/body/thyroid and more health issues. Gluten is wheat/barley/rye..oats may act like gluten with avenin. GMO corn/soy/canola oil may hurt. Amour thyroid maybe needed since gluten may made antibodies to the thyroid.

          Sunlight (helps the immune system and helps to heal the gut lining),exercise, organic food, good water..not tap water, cooking by scratch pure food, no food in a box/bag/premade/label/restaurant which may help avoid hidden gluten. Nuts not sold in the shell/meat basting/some spices may have hidden gluten and lotion/make up etc. One restaurant cooks special for me…rice/veg/tea/extra mushrooms (no meat since the woks may have MSG/gluten in them).

          EDTA/DMPS IV chelations from an Alternative doctor, 600mg of cilantro, zeolites, organic sulfur, Now brand- Detox support and more may help detox. Hair tests show good minerals and heavy metals. Heavy metals can block thyroid and other chemical reactions in the body/brain.

          LDN may help block hidden gluten, but the Celiac diet is still needed. 100% no gluten may help.

          Zinc/Se/enough iron/probiotic may help convert T4 to T3 for thyroid…raises oxygen/energy in the cells. Best wishes.

  • PC

    Thanks for this post Dr Ede! I used to eat rutabaga regularly and could never figure out why it was making me feel “off” after eating it. Interesting that querectin lowers thyroid – I started taking it recently for histamine issues and also noticed feeling a bit off afterwards.

    • Glad you found it useful–I never knew about the quercetin connection either. Those plants…can never trust ’em…

  • Carole Sampson

    Very interesting post, Georgia. Thanks!

  • Marilyn

    Thank you! It’s good to have it all carefully spelled out. I’ve enjoyed your articles and was glad to find a new one today.

    I googled “tyrosine source.” Wiki offers the following list:

    “. . .found in many high-protein food products such as chicken, turkey, fish, peanuts, almonds, avocados, milk, cheese, yogurt, cottage cheese, lima beans, pumpkin seeds, sesame seeds, bananas, and soy products.[4]”

    A list offered by the University of Maryland Medical Center reads: “. . .found in soy products, chicken, turkey, fish, peanuts, almonds, avocados, bananas, milk, cheese, yogurt, cottage cheese, lima beans …”

    I found the position of “soy” in the two lists to be interesting.

    • Hi Marilyn
      Glad you enjoyed the (much belated) post! Yes, tyrosine is an amino acid, so it is abundant in all foods that contain any significant amount of protein, including soy. Any person eating sufficient protein will be getting enough tyrosine, so tyrosine deficiency is only a problem in malnourished individuals, typically in developing countries. The combination of protein malnutrition and iodine deficiency increases the risk of hypothyroidism significantly, which is why goiter is so common in the Third World.

    This is of special interest to me because only a week ago my cardiologist suggested that although my heart is ok now I should get my TSH tested (because of weight loss).

    • Wendy Allen

      Too high or too low of thyroid may affect the heart. Too low may lower energy and oxygen in the heart. Too high may cause faster heart. Coenzyme Q10, B vitamins/carnitine/Ca/Mg citrate 400mg/ 2000mg of fish oil (thins blood) and more may help the heart.

      No gluten/dairy/soy/sugar/GMO and vitamins/good oils, LDN and detoxing help me.

  • Michael Eversberg II

    So with this in mind, should I abandon my tea drinking habits?

    • Hi Michael
      That’s up to you; it is not a source of the strongest goitrogens, but if you have thyroid problems and you have already made other dietary adjustments without any benefit, it may be worth a try…it depends partly on how much tea you drink and how much you would miss it if you stopped drinking it. My guess is that tea is unlikely to be a major culprit on its own. You can also overcome some of the anti-thyroid effects by ensuring adequate iodine intake.

    • Wendy Allen

      I drink tea every other day…Tea may have F that can block I for thyroid. Tea helps heal me. I will continue to drink it but use reverse osmosis water..not tap water that is low in F. The F in tea healed my teeth once from chewing on cranberries that were too acid.

    Glad to see another (very good) post! Thank you! No need to reply–just saying “Enjoyed it and thanks.”

  • carparr

    I use the Himalayan Pink Salt purchased at Costco in its own grinder. Is this (and similar types) of salt have sufficient iodine?

    • Hi carparr
      Good question. I cannot find any evidence that Himalayan salt contains any iodine. The only chemical analysis I found lists the iodine content of Himalayan salt as “less than 0.1 g/kg.” This doesn’t tell us anything meaningful, because we need to know how much less than 0.1 g/kg. It could mean that it contains essentially no iodine, or it could mean that it contains as much as 0.09 g/kg, which would actually be a lot of iodine (0.09 g/kg = 90 g/g = 126 grams of iodine per 1/4 tsp).

    Hello, hello!
    My thyroid level was 7.8 this past week and in the normal range six weeks ago. I have been a vegan less than a year. What should I eat to bring my thyroid levels down?

    • Hello, hello, Christy!
      I cannot provide individual clinical advice on this site, but I would rephrase the question: what should you stop eating to bring your thyroid levels down? There are suggestions within the blog post, so take a look at your current diet and see if you are eating foods that can interfere with normal thyroid function.

    • Jeannine

      Gluten and soy. I’m vegan, my levels are perfect and always 0.8 – 1.5. Eat clean – whole foods, avoid vegan junk, get in exercise no matter what, be kind to yourself, meditate, etc.

    • Patricia Jasmin

      I used to suffer from hypothyroidism for about 10 years so I have tried every treatment & supplement there is. Unfortunately nothing had any positive effect at all on me but after countless online research & trial/error I was actually able to completely cure my hypothyroidism. Here is what worked for me:

      1. Take thyroid hormone supplements. I would suggest speaking to your doctor about which ones exactly as they vary in countries but they offer great initial help.

      2. Follow every step in the free video & guide seen at the following link:

      curehealthproblem*com/hypothyroidism (obviously change the * for a dot as it won’t let me post links here). This will tackle hypothyroidism in a natural way. This is very important.

      3. Take up one of the following: tai chi, yoga or meditation. Not only will it show benefit through exercise but it will improve mental state.

      Try those two steps and hopefully you will get as much luck with getting rid of hypothyroidism as i did. Another final tip is to up the protein in your diet. Just remember it does not have to be a permanent problem, medications may slightly ease symptoms occasionally but you really need to tackle the root cause. Good luck! ….

    • Wendy Allen

      Gluten may cause high/low thyroid. High thyroid may burn out until it is low. No American food..no gluten (wheat/barley/rye..oats)..no GMO corn/soy/canola oil etc may help. I eat Asian style…rice/veg/meat/nuts (open the shell to avoid hidden gluten)/tea/fruit low in sugar and more. Ca/Mg may block thyroid if it is hyper. Soy that is not GMO may block thyroid.

    Its amazing how the importance of iodine has been so quieted. Iodine is found in every cell in your body and is very critical to a healthy thyroid. With the thyroid problems increasing, especially in woman, one would think that the studies on iodine would be the focus. Like the studies that prove that every person with a thyroid disease or disorder has an iodine deficiency!

    According to the World Health Organization’s Department of Nutrition for Health and Development, iodine deficiency is a public health problem in 54 countries. The CDC states that iodine deficiency is one of the four major deficiency diseases in the world and the easiest to correct.

    Very interesting column! Would you have any information on turmeric/curcumin?

  • Amanda

    Hello, I found this very intriguing. I suffer from this. I am always tired and can never lose weight. I am a vegetarian and just about all that I eat is on this list! I don’t want to go back to meat but how can I balance the two, eating from this list and having proper thyroid function? How long should the vegetables cook to reduce their negative effects? Can steaming produce these results? (I posted this comment in a different place on the blog)

    • Antonette Pakay

      Get off soy and uncooked goitrogenic vegetables, add eggs/egg whites, and fish. I was vegan for a year I ate soy and a wide variety of goitrogenic vegetables, I started having memory problems, and extreme fatigue. I had blood work done turns out I had hypothyroidism and Hoshimoto’s disease, everything I was eating caused my thyroid to stop working. I still do not eat any animal flesh, I eat salmon and occasional shrimp for protein.

      • Auggiedoggy

        Salmon and the occasional shrimp IS animal flesh. ;o)

  • Auxane

    Hello,
    It seems that fruit also has negative effects on metabolism (along with vegetables, grains/nuts/seeds). You mention apples, cranberries, citrus, blackberries, apricots… uh…. what CAN we eat then?
    Thanks.

    • My belief is that an all-meat, or at least a mostly-meat diet, is probably the healthiest possible diet for human beings. However, this can be a difficult and boring diet to follow, so if you would prefer some variety in your diet, you would have to figure out which plant foods bother you the least and include them if you’d like. Some people have reasonably good ability to process carbohydrates and do pretty well with fruits but others of us are not so lucky.

      • Edgar Barrington

        What kind of “belief” is that?!!!! That is the worst advice one can give with all the heart and cancer problems caused by fat! Nothing like vegetables and fruits, but I am sure there are good ones among them that one needs to explore. Good advice if you wanna see someone kick the bucket sooner than later!

        • Sean1978

          Fat causes heart and cancer problems???? What fat? Polyunsaturated fat? Not all fat is bad, infact saturated fat is good for you. Where did you get your info from on fat causing these things?

          • Edgar Barrington

            Well, there are good fats and bad fats, Sean. The good ones are Polyunsaturated fats, found mostly in vegetable oils.

          • Sean1978

            Vegetable oils are some of the worst to consume actually and polyunsaturated fats as well, don’t know where you got your research on that? I would stick with saturated fats like Coconut Oil and Olive Oil which are far healthier than most vegetable oils on the market which are loaded with Omega 6 fats etc. Those are the worst honestly (Crisco etc.) and I would rather pass there.

          • Edgar Barrington

            Come on! Coconut oil has been indicated as one of the worst offenders in elevating cholesterol and triggering heart disease. You got a fail on that: 🙂 You might as well load up on hydrogenated items!

            Check this: http://www.webmd.com/diet/coconut-oil-and-health

            The evidence that coconut oil is super-healthful is not convincing and
            these claims appear to be more testimonials than clinical evidence. Coconut oil, like all saturated fats, should be limited to 7%-10% of calories because it can increase risk for heart disease, according to the AHA and 2010 Dietary Guidelines.

            I rest my case. Studies done in India where coconut trees are plentiful shows the danger of coconut oil. Another new fad, and people jump on the bandwagon – when you realize the truth, it is much too late! Too bad!

          • Lol Web MD, take whatever they suggest and do the opposite if you want to be healthy. Following any of the “guidlines” on WEBMD or similar site which promote the antiquated beliefs of the AMA is the most sure fire way to end up sick and on a long list of medications that you otherwise would never have needed.
            I am a personal trainer, but my primary emphasis with clients is on nutrition. I have met dozens of clients who had been diligently following their Dr recommended low fat high whole grain diet, and yet they were overweight, diabetic, had sleep issues, on meds for blood pressure and cholesterol, and many are or were diabetic or prediabetic. Not only were they sick, they were getting sicker, they felt tired and run down much of the time, and just weren’t living up to their potential. Many were also jogging or attempting to job or do other forms of moderate intensity steady state cardio.
            When I meet a client like this the first thing I ask them to do it stop jogging, stop eating grains, and remove all processed vegetable oils along with store bought milk, especially skim, and definitely remove all soy from the diet. Sugar removal should go without saying.
            I have my clients eat a meat and vegetable based diet, generally consisting of about 60% fats, – mostly saturated, 30-35% protein and 5-10% carbs. Red meat, whole eggs, bacon, drumsticks with skin on, and cooked veggies are prominent on the menue.
            In addition I have them complete 2 total body strength training sessions per week and 2 interval cardio sessions. The weight training is typically 40 minutes including warm up and cool down. The cardio is at most 12 minutes of intervals, performed either 30 seconds on 60 seconds off for 8 rounds, or Tabatha style 20 on 10 off for 4 minutes. I ask them to warm up and cool down for 5-10 minutes at 50% effort. Off days I ask for 60 minutes of walking at 60% heart rate.
            The results have been nothing short of miraculous. To a t, every single client who stuck to the plan lost weight, improved their physical fitness and capability, felt better though out the day, and many have been able to be medication free for the first time in a decade or more. I’ve seen cholesterol got from 300+ to 160 just 30 days after switching from a grain/carb based diet to a meat/fat based diet.
            You can spout quotes from Web MD all day long, but those of us who are actually practicing Healthcare in the real world and achieving eal world success know that those types of recommendations are not only outdated and irrelevant, they are down right dangerous and destructive.
            If you don’t believe me I have 100+ clients with real world results to back me up.

          • Dear Tatum

            Fantastic recommendations–I completely agree! Your clients are lucky to have found you!

          • Thankyou very much. It’s so funny to me … my clients have had great success … when they follow the protocol. I have clients in their 70s and even as old as 85 in perfect health able to do 10-20 full push ups and weighted squats and even deadlift. Yes, a mere 4 months after i met her … hunched over her walker which she could go anywhere without .. I had an 84 year old woman doing free weight squats and deadlifts. She was diagnosed celiac about a year before we met, but had eaten grains her whole life and figured at 83 why change. But I convinced her to give me 45 days. She did, and never looked back. At 84 lshe ost 18lbs, became medication free, relieved arthritis and no longer needs a walker… she ate meat and veggies and a little fruit. That’s not what I’m laughing at .. in fact i tear up every time i tell that story…
            I laugh at the fact that many if not most of my clients are medical professionals themselves. And when they see the diet plan I lay out … Oh Boy are they up in arms fighting me tooth and nail. Insisting I’m going to have them keeling over dead as their arteries fill with fat … lol. . Makes me wonder what the hell they teach in medical school…? I’m mostly self educated. Ask a Dr what the body’s hormonal response to a given meal will be and 9 times out of 10 you will be met with a deer in the headlights stare lol. But eventually they give in.
            I don’t get it. It’s really not rocket science. I taught it to my 10 year old neice.. granted shes a prodigy child of my brother and his stupid perfect 1600 SAT score … but whatever. I mean look at nature, before agriculture there simply wasn’t enough edible plant based foods in much of the world to sustain a human population. We know herbivores are not leading the animal kingdom class when it comes to intelligence.. carnivores do. Plant food takes a long time to consume and digest enough to sustain the life of a mammal… hence grazing is the life of most herbivores. Clearly humans dont fit into this category. Meat provides a dense amount of fuel, however raw meat is still difficult to digest. Cooked meat however, now we have an easily digested, nutrient and energy dense food source … the kind that would allow the evolution of the human brain. Hunter-gatherer populations were extremely healthy those individuals who survived childhood for The most part lived TO their sixties or even seventies based on The fossil record. The they say The life expectancy or average age of death was 033 but that’s just an average people typically died either in childhood fell 50% of newborns died in their 1st year that’s going TO dramatically skew The life expectancy those who survive those precarious years often live TO their sixties and seventies and they were very physically able-bodied at that age based on The fossil record. And they were eating meat. When The 1st cities were being built and agriculture dominated life expectancy dropped TO 18. Again still on average this time 0 TO 10 and 3236. However now they were dying of The same things that we are babies R disease and their mid-thirties by The droves and they were fat. How do we know this you ask well The desert around Egypt has given USA thousands of body is TO analyze and The ancient Egyptian diet it was a registered dietitians dream. It venerated on whole grain bread. Every soldier in the Egyptian army was rationed 2lbs of bread a day. This supplemented with home grown veggies and fresh fish from the Nile… obese and dead at 35 of diabetes. Not only did The life expectancy in quality of life decreased dramatically upon The shift from animal-based food TO grain-based physically The species underwent a dramatic decline as well. Average global Hiett fell by about 5″ per individual number of dental carries per individual increased from an hour bridge of 0.5 TO 7 and incidence of bone malformation when Up quite a bit I don’t have a statistic for that. And I mean come on look at the hormones you eat carbs your blood sugar spikes you release insolent do it over and over you become resistant the pancreas where is out it simple it’s a direct cause and effect relationship 1 0f the only ones in biology and the medical community just doesn’t get it it’s it would be whole areas if it wasn’t killing tens of thousands of people a year and costing this nation billions of wasted dollars and gets me kind impeded evidently. Why is it left to the lowly personal trainer to educate the doctors on how to be healthy without a million medications and chemical cocktails…

          • Lots of voice text fails in there … but I don’t feel like editing .. so i will simply acknowledge

          • Jennifer

            Thank you Tatum Parks. Your recommendations were right on target. I’m going to incorporate the ones I haven’t been usuing.

          • Thank you too! Best of luck to you, and feel free to let me know if you have any questions or ideas to bounce around.

          • Edgar Barrington

            Sorry, I fail to be swayed. I stayed off meats (except for chicken once every two weeks), ate fish once a week, NO red meat at all, speed-walked for 30 minutes every other day, drank 3 to 4 cups of coffee or chai a day using full or skim milk, no weight training at all, and around 8 glasses of water a day and lost 15 pounds in 3 months and have stayed at that level since December.My general lunch and supper were one or two “chapatis” (I was in India) made without oil along with a spicy chick pea preparation. Never felt better. In other words, the variables are different for different folks.

          • You lost weight because you were in a severe caloric deficit. it’s been clinically proven that even if one eats nothing but Twinkies, as long as they are in a caloric deficit, they will lose weight. Now lets break this down – losing WEIGHT is very much different than losing fat. If one loses weight, but all the weight lost is muscle, that would be bad – for example. When a person loses weight by restricting calories and performing cardio exercise only with no strength training, as you so proudly state above, a number of bad things happen, that set the person up for a difficult time down the road.
            1. On average, a person loses 1 lb of muscle for every pound of fat lost. Why is this bad you ask? because calories are burned in muscle. The more muscle you have, the more calories your body burns at rest and the easier it is to maintain low bodyfat levels. Conversely, by losing muscle, the person now burns fewer calories at rest. If they want to continue to lose weight, they will have to continue to further restrict calories to remain in a caloric deficit. This is simply not sustainable, eventually the person goes off their severely restrictive diet and back to their old habits. This trend is very common. Now the real fun begins as the problems start to snowball. Back to their old habits, our subject quickly regains the weight they lost. Recall that the weight lost came from a combination of equal parts fat and muscle, unfortunately unless they suddenly take up weight training, the weight regained will be all bodyfat. Worse than being back at square one, the person is now back to the original weight, but with less muscle, more fat and thus a slower metabolism. Now if the person decides to try to lose weight again, it will be even more difficult than the first time.
            2. THEY LOSE MUSCLE. Less muscle mass at the same weight = a higher bodyfat percentage = increased rate of pretty much every disease state. Less muscle means they will be weaker and less physically able overall – which leads to a decreased quality of life. Maintaining functional strength is vital if one hopes to maintain independence as they age – strength training should absolutely be at the center of any long term health maintenance plan.
            2.5 Based on what you said you did, I’m willing to bet that you lost more muscle than fat in the first place, and likely threw yourself into hormonal imbalance. “Speed walking” implies you were not walking at a relaxed pace, but rather intent and focused on fast walking….. maybe even to the point of being stressed or not at ease during this activity. First of all, if your heart rate exceeded 70% of its theoretical max (or less for some people who are deconditioned) you and your body become unable to use stored body fat as a fuel source, it simply can’t keep pace. 60-70% HR is reached in just a minute or 2 when doing anything besides casual easy paced walking or other low effort activities. So you weren’t burning fat for fuel while speed walking. Instead you first use up stored glycogen. If you continue to press on once glycogen stores have been depleted, your body will release catabolic hormones which breakdown and mobilize both stored fatty acids and amino acids from muscle tissue. In all but the highest level of endurance athletes who have moved into the modern era of sports performance (that is they no longer consume high carb diets or carbo load (which we know doesn’t really work as imagined anyway) and instead, through specific training and nutrition techniques, forced their bodies to learn to use fat for fuel at higher levels of exertion) the fatty acids that cortisol mobilized end up simply being restored. The problem is they are mobilized from subcutaneous stores, and restored as the more dangerous visceral fat stores in the abdomen. So basically the moral of the story is, you were burning up your own muscles to provide energy on your walks. As is this weren’t bad enough, your diet was very low in protein, likely deficient realistically, meaning you didn’t provide your body the necessary tools – amino acids – to repair itself.
            3. Over time the muscles become weaker and smaller, they are less able to aid in supporting your overall body mass. This must be accommodated for if the person hopes to maintain posture and structural integrity as they age. The body has a just such a built in mechanism, but it is a double edged sword indeed. here comes fascia to the rescue. As damage accumulates in muscles that unable to repair themselves properly, the surrounding fascia becomes thicker and denser. Immobilization of damaged tissue is necessary for the body to repair itself. Adhesions form in and all around damaged muscle tissue in an effort to keep it immobile . This is bad for 2 primary reasons, but this is getting long so I’m going to skip them. Suffice it to say that many of the symptoms of aging commonly experienced such as loss of height and range of motion, as well as shakiness, loss of balance and coordination can all be attributed to fascial constriction.
            4. i don’t know what chapitas are, but I assume they are not an animal product, and carbs are their primary macro nutrient. carbs are not an essential part of anyones diet. A human can go their entire lifetime and never eat a single gram of carbohydrate and lead a very healthy life. Try to go a lifetime without EFA’s or EAA’s and it will be a short life indeed. essential fatty acids (like those found in the oil you turned your nose up at) and essential amino acids are just that – essential. If you do not eat them, you will die. Let me repeat. Fat is essential, if you do not eat it you will die. Period.
            5. Your diet featured a lot of legumes. once touted as a health food, like grains, legumes are slowly falling out of favor by the research community. They are pro-inflammatory, damage the intestinal lining making it more difficult for the body to absorb nutrients. They also contain a class of “anti-nutrients” called phytates. Phytates bind to and block absorbtion many minerals including calcium, iron, magnesium and more and strip them from the body.

            you lost 15lbs in 3 months and maintained it for 5 months so far – or at least as of your last update. I can easily go up or down 15lbs in 3-5 days and effortlessly maintain it indefinitely. Per my assessment, you did a fair amount of damage to yourself in the long run, and I just realized I didn’t even get into a discussion of the hormonal disruption you caused yourself, oh well, I’m tired. I don’t doubt that you felt better in the short term. Likely you went off a diet of processed or toxin laden foods accompanied by a sedentary lifestyle and started eating whole foods and at least walking. Sure you’re going to feel a little better. …. But not even close to how good you could potentially feel. And once intestinal and digestive distress sets it, along with fascia pain, weakness, and loss of bone density ….. well, i doubt we will hear about it here.

            For people with thyroid disorders, your advice is the worst. Coconut oils and the fiber is one of the best things a person suffering from hypothyroidism can incorporate into their diet. Edgar Barrington, your advice may work and be healthy for those without this disorder, but anyone who follows your advice with this disorder will end up having high TSH levels. You aren’t talking about a normal functioning body when you are discussing hypothyroidism. You are talking about a body that is shutting down.

          • Edgar Barrington

            Hmm…can you post some links to *reputable* studies supporting this? Mayo Clinic, Harvard Medical School, etc? In fact, I do have that condition and would do anything to get off this Thyroxin usage cycle!

          • Edgar Barrington

            I re-read the WebMD post again. The more I read it, the more sense it makes. It is also supported by the Harvard Medical School study. Yes, what you are saying regarding hyperthyroidism might be true, but for the heart, it is different story. A wise man once said, “Everything in moderation”. A good credo, indeed. Coconut oil should be used minimally.

          • omega 6 polyunsaturated fat, like those found in vegetable oil are, aside from a few exceptions like CLA, very pro-inflammatory. Inflammation results in disease states. seriously…. where do you get this stuff?
            Given that a large percentage of the human brain is composed of saturated fats, and you apparently don’t eat any ….. by the logic of someone who argue that eating fat makes you fat because its fat (you), maybe you are simply missing half your brain. please stop posting misinformation that could be potentially damaging to peoples’ health.

          • Thatiane L.

            Thank you so much for all that information, Tatum Parks! I have one question: how long should i stay without eating after i do my daily workout rotine? Normally i eat something and wait 1 hour to start my exercises then i do 1 hour of exercise (i follow the calendar of a fitness youtuber called bloglites) when i finish i like to stretche (i think i spend also 1 hour with that, i’m aiming for more flexibility). If i add all it gives me 3 hours (more or less) without eating, is that ok? i should eat after i finish the workout and only then do the stretches or should i keep doing what i do that is eat after i’m done with all. I’m scare being without eating that 1/1 and a haf hour that i take to do the stretches i will be losing muscle. Sorry for the bad english i hope you can understand what i mean

          • You will not lose any muscle by waiting an hour to eat. In fact depending on your goal I usually recommend to people to wait sixty minutes to eat post training. Unless your goal is pure weight gain if you want to just gain weight eat immediately. If you want to lose body fat and get toned wait an hour. Reason being is post workout your body releases growth hormone if you do not heat and insulin if you do eat. Growth hormone burns fat and repairs connective tissue .. among other benefits. Insulin is The storage hormone. It Forces excess blood sugar into storage cells where it will not harm The body. Stretching for an hour is pretty excessive though about twenty minutes three to four times a week is plenty. I went from barely being able to touch my knees to bending over and putting my hands flat on the floor stretching twenty minutes three days a week and that took me about three to four months. Don’t make stretching uncomfortable it should be about relaxation. There’s no need to push it you will only damage your joints and connective tissue by forcing stretching. He should feel it in the muscles not the joints that’s important. Just simply go to the edge of your comfort zone and relax focus only on your breathing and as you inhale maintain your position as you exhale you can typically go a little bit further into the stretch hold each stretch for a good probably eight twelve breaths or so about twenty seconds fifteen to twenty seconds no need to hold a stretch longer than that.

            Thank you, you’re awesome!!! I have hypothyrodism and it’s extremely hard find good information about what should i be eating, every site says something different, it’s driving me crazy! I changed my diet a couple days ago for a kind of paleo/LCHF modified, i add a bunch of greens and stop eating beans and rice (that was what i normally would eat), even the fruits i changed, i used to eat grapes and exchange to strawberrie but now i saw that i couldn’t be eating those greens and the strawberries because of the goitrogens so i will have to change everything again. Do you think is ok to eat an apple and onions everyday even with the quercetin/apigenin situation? I like to eat to pair a fruit in my pre workout, i was eating the grapes then i exchange to the strawberries and now i was think to change again to the apples but seems like i still could’nt be eating that… I’m lost.

          • Greens are fine if they are cooked. I’m pretty sure broccoli is high on the offender list. Aspargus is great though. Brush with olive oil then bake at 400 degrees for 10 minutes. Top with grated parmesan.. delicious and nutritious. Eat your veggies, just cook them. I’ve not heard of berries being a problem before … But I’m not an expert on hypothyroidism. Strawberries do have the highest anti oxidant content of any berry … commonly credit is given to the blue berry in this category but that is another common misconception that’s gets repeated and no one ever actually looks into it… like the original study done in the 1950s that concluded saturated fat was a heart health risk…. and it became accepted common knowledge… then established tradation… and here we are today… without getting too far off topic … It was Probably 1 0f the worst designed studies ever and it wasn’t even really a study it was a meta-analysis of 500 people who already had heart disease … Looked at what they had eaten and their life and just concluded that it must have been The saturated fat that did it that’s it. …Stupid.
            Apple’s are great great too though. They have a Specific type of fiber called pectin which does good things for you … sorry I’m short on time so not elaborating. Pears have it too. Mix it up. One day eat an apple … the next a cup a mixed berries.. then maybe an orange or a couple kiwis … I like tangerines myself and eat 2 or 3 a day … sometimes more lol. Same with veggies. That way you can be sure to get a full spectrum of nutrients.

            So i will be eating this: starting 11:40/12:00 snacking in 6/10 walnuts, around 14:00/14:30 i will eat my pre workout (option 1: split one avocado on half and eat the half of the split part with one tablespoon of cocoa powder and a little bit of honey with 6/7 strawberries or 1 apple i’ll try to switch the fruit from time to time, or option 2: 2 scrambled eggs with black pepper, oregano, onions, bell pepper, tomatoes made with half a spoon of butter and the same fruits of the option 1, or option 3: same as option 2 but adding half of a slit in half avocato with black pepper, oregano, onions, bell pepper, tomatoes, little bit of vinegar and maybe some olive oil. Then i wait 40minutes/ 1 hour and do my workout and stretche routine after i finish around 17:30/18:00 i eat my pos workout (1 or 2 bannas and one boiled egg or just the bananas). 20:16 i eat for the last time a bowl of vegetables (carrots, beets, zucchini, lettuce with with black pepper, oregano, onions, bell pepper, tomatoes, Squash, Cucumber, the other half of the slip avocado, one tablespoon of vinegar and olive oil) with one or two boiled egg or two chicken breast or sardine. Is that ok? I already have a skinny body but i have a very big poochy belly since forever that i want to get ride of and of course tone and strengthen my body as much as i can and try to improve or even heal my hypothyroidism so the healthy is number one right now.

          • What’s your age height and weight? Why do you not eat until noon?

          • Thatiane L.

            I’m 19. 5 feet 6 inches tall (1.70m). I’m not sure about the weight, i rarely weight myself, last time i did i was 110 lbs so i would say around 110/115 lbs (50/52kg). Because that’s the time i wake up lol I’m not in college yet so yeah i sleep a lot lol

          • I can say with 90%+ confidence that the Beans and rice was the source of your pooch belly. Likely combined with fascia restriction and “stuckness” in your intestines as a result of chronich inflammation from a lifetime of eating foods you may be allergic to. If it’s hashimotos hypothyroidism it’s probable that your diet was a large contributing factor in it’s development and adopting a Paleo diet will be your best weapon to combat it. I saw all kinds of benefits when I made the shift. Fixed my anxiety and sleep troubles, cleared up chronic joint pain and shin splints I’d had since I was 15, i now effortlessly maintain 8-10% body fat,I sleep soundly 6-8 hrs straight and I wake up at the same time every day without an alarm feeling refreshed and ready to just hop out of bed and go. Perhaps best of all for me though … no more allergies! I had them so bad I had to get weekly injections for the first 20 years of my life. Even so I could hardly go outside in spring.. contacts were out of the question… now I can stand in a cloud of pollen and hardly sniffle. It’s absolutely amazing.

          • Thatiane L.

            I think i look a little bit less bloated already after i stopped with the rice and beans which is great! i suffer a lot with anxiety as well, i hope it help me with that aswell

          • A Paleo diet in general will gi a long way.

          • Oh and breath thru your nose while stretching … full deep breaths feeling the lungs fill up all the way to your belly. Nice and steady. Try to imagine just being your breath. Stay in the moment .. this is ME time … forget about everything thing else and for that short time. … Just be. It goes a long way for mental health as well.

    • Wendy Allen

      See my above comment. No gluten/dairy/soy/sugar/GMO…vitamins/good oils, LDN, detoxing may help. I avoid soy mostly and cook the cruciferous family of vegetables. Taking Zinc/Se/enough iron/probiotic may help convert T4 to T3. I now take bioidentical hormones….estriol/progesterone/testosterone. Progesterone helps get the thyroid medicine into the cells. This is enough to help me. Best wishes.

    Hi Dr. Ede,, excellent info on your site! I’m so glad I found you!

    I am an almost all meat eater, also an endurance runner, and it works for me!

    Following 10 years on a strict vegetarian diet, (very high carb, grain heavy), I had an enlarged thyroid and went to a naturopathic doctor who told me to take liquid Iodine…(the yellow tincture you put on cuts), and put it all over the soles of my feet before bed. My body would absorb what it needed. When I woke up in the morning and my feet were still yellow and my body had not absorbed it, to stop applying it.

    I painted the soles of my feet each night and every morning it would be gone, for 4 nights…then on the fifth morning i woke up and the soles were all yellow, like I had just finished applying it, it was bizarre…i knew I didn’t need any more.

    Obviously I was very deficient though. Oh and my thyroid is back to normal size.

    I thought this might be interesting to your readers…

    All the best,
    and thanks

    • That is fascinating! Thanks for sharing this, Jade.

    hello Dr
    i am taking medicine thyroxin sodium tablets 150mg for hypothyroid for last 2 years and the medication is for lifetime ,in such condition what should be my diet .can i recover compleatly from medication

  • Kelly

    If one has hypothyroidism, and they are primarily vegan, what else can they eat? I had breast cancer a year ago, and I have been encouraged to eat cruciferous veggies, because I am estrogen dominant. But according to your article, I can’t have these or many other vegetables. Can you explain? What then, since I’m primarily vegan, can I eat??

    • Hi Kelly

      Yes, a vegan diet can be challenging when it comes to avoiding goitrogenic foods, but so long as you minimize or thoroughly cook the major culprits (crucifers, millet, soy, etc.) and steer towards protein-rich plant foods not listed in the article (nuts, for example?), you can reduce risk to your thyroid gland. You may also find the series of blog posts on cancer helpful.

    • Wendy Allen

      Vegetarians maybe Celiac…don’t have enough zinc to help digest meat. I take HCl and enzymes with meals and zinc/Se/enough iron/probiotic to convert T4 to T3. Meat has iron..may help. Cook cruciferous vegetables. Broccoli has DIM which may bind estrogen more. Taking zinc may make testosterone…balance out estrogen. Nuts need to be sold in the shell..open them to avoid hidden gluten. Cancer/low thyroid can be due to Celiac which causes low oxygen/pH due to low nutrients absorbed in the intestines…then cells are not made right to work right.

      No gluten/dairy/soy/sugar/GMO and vitamins/good oils, LDN and detoxing help me. Vit D3 5000IU, zinc 50mg, fish oil 2000mg, 20000mg of evening primrose oil. 2000mg of lecithin, krill oil, coenzyme Q10, rhodiola, Mg citrate 4000mg, Vit C, 5000mcg of biotin, Nature’s Plus- Source of life multiple, HCl and enzymes with meals, dairy free probiotic, Vit B12 methylcobalamin shot/spray/under the tongue kind/intrinsic factor kind, MTHF folate, coenyzme Q10, rhodiola, may help brain/body/depression/cancer/thyroid and more health issues. Gluten is wheat/barley/rye..oats may act like gluten with avenin. GMO corn/soy/canola oil may hurt. Amour thyroid maybe needed since gluten may made antibodies to the thyroid.

      Sunlight (helps the immune system and helps to heal the gut lining),exercise, organic food, good water..not tap water, cooking by scratch pure food, no food in a box/bag/premade/label/restaurant which may help avoid hidden gluten. Nuts not sold in the shell/meat basting/some spices may have hidden gluten and lotion/make up etc. One restaurant cooks special for me…rice/veg/tea/extra mushrooms (no meat since the woks may have MSG/gluten in them).

      EDTA/DMPS IV chelations from an Alternative doctor, 600mg of cilantro, zeolites, organic sulfur, Now brand- Detox support and more may help detox. Hair tests show good minerals and heavy metals. Heavy metals can block thyroid and other chemical reactions in the body/brain.

      LDN may help block hidden gluten, but the Celiac diet is still needed. 100% no gluten may help.

      Zinc/Se/enough iron/probiotic may help convert T4 to T3 for thyroid…raises oxygen/energy in the cells.

  • Tonya

    My son has Hashimoto’s Hypothyroidism. He has had a normal T4 for about 1 year but we haven’t been able to get a normal TSH. His doctor has always asked me if he ate anything soy; I didn’t make the connect that he actually was eating soy until now. We are eliminiating it from his diet. i realized he has been eating a processed dish almost daily that contains soy. His last TSH level was 30. It ranges from 10-30 usually. Do you think soy could make his TSH run that high?

    • Hi Tonya

      I suppose it is possible, but the only way to know for sure is to do exactly what you decided to do already–to eliminate the soy and see if it makes any difference.

    • Wendy Allen

      Soy maybe in 60% of food that is premade in the grocery store. Any premade food may also have other bad ingredients…GMO food/gluten/chemicals etc. Eating pure foods may help. Soy greatly hurt my hormone. It gave me energy, but eating meat would also do that or B vitamins. Soy is GMO..may destroy health. Zinc/Se/enough iron/probiotic may help T4 change to T3 for thyroid.

      No gluten/dairy/soy/sugar/GMO and vitamins/good oils, LDN and detoxing help me. Vit D3 5000IU, zinc 50mg, fish oil 2000mg, 20000mg of evening primrose oil. 2000mg of lecithin, krill oil, coenzyme Q10, rhodiola, Mg citrate 4000mg, Vit C, 5000mcg of biotin, Nature’s Plus- Source of life multiple, HCl and enzymes with meals, dairy free probiotic, Vit B12 methylcobalamin shot/spray/under the tongue kind/intrinsic factor kind, MTHF folate, coenyzme Q10, rhodiola, may help brain/body/depression/cancer and more health issues.

  • Kerry

    My thyroid level started at .8. I went to the Dr. and they put me on medication. However, my thyroid level went even higher than before. It went to .43. I told my Dr. that I was having very bad thoughts, depression, lethargic etc. She said that she has never heard of anything like that in 25 years. She recommended that I continue my medication. I took it upon myself to stop my thyroid meds. I feel much better now, but I would like to change my diet. I need to bring my levels down or at least keep an eye on them. I came searching for foods to lower thyroid levels. Hopefully with your list of foods it will work. Thank you for your help!!

    • Good luck, Kerry!

    • angela

      Kerry, I would suggest a doctor less full of crap, that is exactly what synthyroid did to me, take a look at Wilson’s syndrome, if it sounds relative then try adding 200 mcg of selenium to your daily supplements. Without selenium there is no point in taking iodine, and is useless. I was surprised not to see that iin the above article, maybe I missed it.

        • Dear Amjad

          I am very sorry to hear about this. I not an endocrinologist and cannot provide personal medical advice on this site, so please take her to a doctor for an evaluation–perhaps a different doctor for a second opinion, if that is possible.

        • Impervious007

          We’ll have you run any blood tests? Have you checked her thyroid, here is a little assistance for what to consider as a cause;
          High TSH – High levels of TSH are typically caused by an underactive thyroid or hypothyroidism. This is typically caused by Hashimoto’s thyroiditis. If you are already being treated for a thyroid disorder this can be a sign that you need to increase your medication. In rare cases, you may be showing high TSH levels because you have developed a tumor that is causing the pituitary gland to over-produce TSH.
          Conditions that Cause High TSH
          Once it is determined that you have excessive levels of TSH in your system, your doctor will start narrowing down what is causing the trouble.

          Hypothyroidism – Hypothyroidism is a condition that is defined by your body failing to produce enough hormones to adequately manage your metabolism. Patients suffering from this condition will typically experience dry skin, increased sensitivity to cold, thinning hear, impaired memory, muscle aches, puffy face, unexplained weight gain, constipation, fatigue, hoarseness, elevated cholesterol, irregular menstrual periods or depression. A number of circumstances such as surgery, taking psychiatric medications, radiation therapy or an autoimmune disease can lead to this condition. Hypothyroidism is typically managed with medication that will artificially replace these hormones.
          Pituitary Tumors – In rare cases, excessive TSH levels are a sign that your pituitary gland is not functioning properly. In some cases this is because a group of cells has begun to grow on top of the gland. In most cases these tumors are not cancerous, but they can cause interference in your bodily functions that can lead to other negative side effects which could be dangerous to the body. The overproduction of TSH can lead to an overactive thyroid.
          Thyroid Disorder – Thyroid disorders such as enlarged thyroid gland, cancer or abnormal hormone production can cause the thyroid to function poorly. Some of these conditions are harmless, but many will require medical intervention to avoid unpleasant side effects such as a sluggish metabolism that will lead to damage throughout the body.

    • Wendy Allen

      See my other comments….Synthroid only may not convert to from T4 to T3. Zinc/Se/enough iron/probiotic may help convert T4 to T3. See Suzy Cohen book on thyroid.

  • Jigo

    Hello
    I’m a teenage girl suffering from hypothyroidism. I’ve been putting weight since i remember. My metabolism is horrible. I’ve tried many many many diets. The low calorie diet, only vaggies & fruits diet, loads of exercising, starvation, no-sweets diet. And none of them helped me even a slight bit in getting rid of my obesity. Gosh, please, somebody help?

    • Hi Jigo

      I’m sorry to hear about all the troubles you’ve been having! If you have never tried a healthy, whole foods, low-carbohydrate diet (as opposed to simply a no-sweets diet), you may want to consider it. Reducing total daily carbohydrates to less than 50 grams per day can be very helpful with weight control. You can read about low-carb diets under my diets tab, and I would also recommend http://www.dietdoctor.com , which is Dr. Andreas Eenfeldt’s excellent website about healthy low-carb diets for health and weight control. Good luck!

        It may help constipation, but I take HCl and enzymes with meals to digest them and eat no gluten/dairy/soy/sugar/GMO…take vitamins/good oils, LDN, detox. See my other comments. Best wishes.

    • angela

      I hate to say it but you will battle this your whole life and if would like the honest to God truth, I was in your shoes at one time. I have been dealing with hypothyroidism since before I was a teen, I don’t care what any doctor says. I went to see a doctor about this rash I got after drinking Jack Daniels, which made me very sick. Why this dr visit ended with them taking 7 vials of blood and calling back in less than a week emphasizing I see an endocrinologist right away. Because it was an obvious thing just looking at me, and then I got this urge to want to stop suffering and take control over my body. My meals never digest correctly and I knew that, so I fought back by using laxatives, I was seriously losing almost 5 lbs a week from that alone. Then began the battle with binging and purging, literally the guilt of what I ate was enough to gag me, that even now if I actually focus on it, I instantly feel like throwing up. By sixteen I’d graduated to diet pills, lucky for me, ephedra was still legal. I used to take the original until one day, and this may sound really weird but, a family friend, and retired fellow officer of my father got onto this whole health kick after moving to Las Vegas. Apparently while doing his usual purchases at a health kiosk at the mall, he bought this little droplet bottle. I don’t know the name of it I can just describe it, it was about 2 1/2 inches long, little cylinder plastic droplet bottle, the label was yellow with a red lightening bolt, I can’t remember what words were on it but “energy” anyway I believe the top was a red pointy twist off cap, inside the bottle was either clear or white and the liquid was almost as dark and similar to the color of coffee. The directions were vague but I don’t think you were supposed to exceed 4 drops, and it was supposed to go in a large drink. Well me, being the brainiac that I was, would put 3-4 drops in like 4 oz of soda and downed it. I would notice it made me jittery but I would soon find out the extent of this options powers.

      • Wendy Allen

        Alcohol may drain vitamins out of a person. Gluten/GMO corn may hurt intestines so nutrients don’t absorb. I take HCl and enzymes with meals to digest the food. Mg citrate 400mg may help constipation along with thyroid medicine and zinc/Se/enough iron/probiotic may convert T4 to T3 for thyroid medicine. Laxative may drain vitamins out of a person along with not digesting the food. People have died from bingeing/dieting/pep drinks etc. Celiac diet may help eating disorder/addictions/low thyroid and much more. See my other comments.

    • Wendy Allen

      Too low in calories makes the body hold the weight. Fruit may add weight except apples/lemon/lime/cranberry/rhubarb…but dilute in water so less acid on teeth. Fructose goes straight to fat..not energy. Paleo/Celiac diet..eating more protein may help. I take Synthroid/Amour combo of medicine. Synthroid only or generic kind may not convert T4 to T3 unless you take zinc/Se/enough iron/probiotic. Below is the short form of what I do:

      No gluten/dairy/soy/sugar/GMO and vitamins/good oils, LDN and detoxing help me. Vit D3 5000IU, zinc 50mg, fish oil 2000mg, 20000mg of evening primrose oil. 2000mg of lecithin, krill oil, coenzyme Q10, rhodiola, Mg citrate 4000mg, Vit C, 5000mcg of biotin, Nature’s Plus- Source of life multiple, HCl and enzymes with meals, dairy free probiotic, Vit B12 methylcobalamin shot/spray/under the tongue kind/intrinsic factor kind, MTHF folate, coenyzme Q10, rhodiola, may help brain/body/depression/thyroid and more health issues. Gluten is wheat/barley/rye..oats may act like gluten with avenin. GMO corn/soy/canola oil may hurt. Amour thyroid maybe needed since gluten may made antibodies to the thyroid.

    • Wendy Allen

      Low K..maybe low in all minerals like Mg which would relax muscle. Taking only K may unbalance a person. 100% no gluten (wheat/barleyrye. oats) may help more minerals absorb in the intestines.

        I’m a bit concerned after reading this info. I have been a vegan for 4 years and last year, after having my son I developed a sluggish thyriod. Allthough I’ve battles with depression for most of my adult life. I may have had the condition all along. I so eat quite a lot of soy & my whole diet is vegtable based. I just thought thyriod problems were heredity as my mum & sister also suffer. There are also insulin dependent diabetics In my close family… I don’t think I could ever go back to meat but I’ve come of my medication as it was making me very aggressive with my children & I felt constantly stressed. The dr told me this was not the medication doing it but as soon as I stopped the those statins went away. Although I may now go back on meds as when I’m working outside I can’t feel my hands & they stop working! & I’m very sad most of the time. Any advice? Thanks

        • Wendy Allen

          Soy maybe GMO and may block thyroid. Low thyroid/Diabetes/Depression. Sadness can be due to low oxygen in the brain/body. Statin drugs cause heart failure as they block coenzyme Q10. Numb hands…low B vitamins and thyroid. My thyroid stopped after my son was born, but was trying to stop before. Babies drain vitamins/good oils out of the mom. The thyroid need Zinc/Se/enough iron/probiotic to convert T4 to T3. Synthroid/Amour combo helps me.

          LDN may help block hidden gluten, but the Celiac diet is still needed. 100% no gluten may help.

    • Wendy Allen

      Just cook the curciferous family and then they hurt less. They have Sulfur which may help detox. People can take organic sulfur also. Best wishes.

  • Kelly

    Hello, I have Hoshimoto’s and I am a 45 year old perimenopausal female. This past year I have gained 15+ pounds. I eat like a bird and no weight comes off. I have researched online for the perfect thyroid diet and still unsure what diet is best. I need a step by step program. Any suggestions?

    • Nicole-Lee Serfontein

      Google Marc Ryan & Amy Myers both dr’s in the USA they both deal with hashimoto’s ! As Hashimoto’s is a autoimmune disease they focus on that ! They both have excellent success rates with the diets they have you follow etc.

    • Hi Kelly
      While I cannot give personalized medical advice on this site, what I can say is that weight control is almost entirely about insulin regulation, which means that it is mostly about carbohydrate intake. I don’t know if there is a perfect thyroid diet, but I can say that, in addition to the thyroid diet advice I provided in the article above, if you have not tried reducing carbohydrate intake or at least eating a low glycemic index diet, I would highly recommend it. Please see my DIETS tab for more information about low-carb and low glycemic index diets, and also my “Carbohydrates” page (under the FOODS tab) for more information. Best of luck!

    • angela

      Hi Kelly there is a women who was able to do just that, I believe her approach was to eliminate glutten in the diet, there is also the paleo diet which may help. I would also consider trying a full body cleanse before attempting any diets or supplements, sometimes you need a fresh start. If you don’t have high blood pressure a simple try would be, in the morning before eating anything else, take a bottle of water, room temp or lukewarm and add two Tsp’s (not tablespoons) of SEA salt, NOT table salt. Give it a chance to run thru, usually about 30mins to an hour and it should flush out many of the toxins and such. People with Hashimoto’s have done well trying fulvic acid/humic… But my newest focus is good o’l fashion colloidal silver, it’s always good to have some on hand. I also believe parasites have been known to cause unexplainable weight gain, along with inability to lose it, a good candida or parasite detox are on the market ranging in price.

      • Wendy Allen

        Colloidal silver poisoned me…blocked my thyroid and other chemical reactions in my body. I needed EDTA/DMPS IV chleations to detox it and survive.

    • Wendy Allen

      See my other comments. Bioidentical hormones may help..progesterone helps get thyroid medicine into the cells. Best wishes.

  • Poonam

    hello
    i am suffering from hypothyroidism and with not regular periods.what should i do to maintain the proper cycle of my body.i gained 20kgs..please suggest me something!

    • Wendy Allen

      Gluten may cause PCOS or other hormone issues. Gluten may hurt all the glands of the body and thyroid. When you absorb more nutrients…then periods maybe better. Best wishes.

      No gluten/dairy/soy/sugar/GMO and vitamins/good oils, LDN and detoxing help me. Vit D3 5000IU, zinc 50mg, fish oil 2000mg, 20000mg of evening primrose oil. 2000mg of lecithin, krill oil, coenzyme Q10, rhodiola, Mg citrate 4000mg, Vit C, 5000mcg of biotin, Nature’s Plus- Source of life multiple, HCl and enzymes with meals, dairy free probiotic, Vit B12 methylcobalamin shot/spray/under the tongue kind/intrinsic factor kind, MTHF folate, coenyzme Q10, rhodiola, may help brain/body/depression/cancer and more health issues. Gluten is wheat/barley/rye..oats may act like gluten with avenin. GMO corn/soy/canola oil may hurt. Amour thyroid maybe needed since gluten may made antibodies to the thyroid.

      Sunlight (helps the immune system and helps to heal the gut lining),exercise, organic food, good water..not tap water, cooking by scratch pure food, no food in a box/bag/premade/label/restaurant which may help avoid hidden gluten. Nuts not sold in the shell/meat basting/some spices may have hidden gluten and lotion/make up etc. One restaurant cooks special for me…rice/veg/tea/extra mushrooms (no meat since the woks may have MSG/gluten in them).

      EDTA/DMPS IV chelations from an Alternative doctor, 600mg of cilantro, zeolites, organic sulfur, Now brand- Detox support and more may help detox. Hair tests show good minerals and heavy metals. Heavy metals can block thyroid and other chemical reactions in the body/brain.

      LDN may help block hidden gluten, but the Celiac diet is still needed. 100% no gluten may help.

      Zinc/Se/enough iron/probiotic may help convert T4 to T3 for thyroid…raises oxygen/energy in the cells.

  • Hello, Aquarius

    Thank you for taking the time to post your thoughtful comments here. I agree that we are told that vegetables are important in fighting against cancer and that we need their antioxidant properties to be healthy, but unfortunately there is no evidence for these claims, strange as that may sound. If you are curious to take a closer look at the science behind these claims, please see my “Vegetables” page (under the FOODS tab) or see my vegetable video, which is posted on the home page of my site.

    • Chris

      I was born with underactive thyroid (I’m a 62 year old female) and have been eating veggies all my life. However, I have thinning hair and the doctor says my thyroxin is the right dose, so what’s going wrong?

      • Wendy Allen

        Gluten (wheat/barley/rye..oats) may cause hair loss as it affects thyroid and other glands/hormones. GMO corn may also hurt. Gluten/GMO corn may lower nutrients absorbed in intestines. Hidden gluten is in premade food. LDN may help block hidden gluten. See my other comments. Best wishes.

  • Hello, Knut

    Thank you; I completely agree that cancer prevention data are misty (i like that word!). I also have no problem disagreeing with, or at least calling into question, the science behind the opinions of the experts. Please also see my blog post about cruciferous vegetables if you are curious about the science behind broccoli and cancer. There is a link to the article on my home page. I guess all I’m saying, in a nutshell, is I’m not convinced by the science and think the jury is definitely still out when it comes to veggies and cancer, unfortunately.

  • orangeman

    This is an except from the site you referenced:
    “scientists caution that while broccoli appears promising as an excellent
    food for preventing cancer, the results of such studies cannot be
    considered by themselves. The anti-cancer effects of any single food
    cannot be completely understood without looking at it as part of a
    bigger dietary picture. It is still unclear, for example, whether the
    phytochemicals in broccoli have benefit on their own or whether it is
    the vitamin C, beta carotene, folate, and other compounds, working
    together and in the right quantities, that might protect people against
    cancer. ”

    Dr Ede was right, the study is at best, inconclusive.

  • TS

    Looking at this list, I can see almost all good food is banned !!!! I have hypothyroidism and mine is 12.5, although I am under medication. Dr. Ede, could you please provide a list wherein I can see all that I can practically eat ?
    The reason is that I am more of a vegetarian (I eat chicken/fish, but almost only once in a week). If I do not eat green leafy vegetables (I can see flax seeds as well in the forbidden list 🙁 ), what do I eat basically ? Also, almost everywhere low fat milk is not recommended due to artificially injected hormones content in it. I do not understand what to eat. Please post the list It would be really very helpful.

    • Wendy Allen

      Flax may not convert to what is in fish oil in 80% of people. More protein may help. Some eat raw dairy and say it is ok. Cook cruciferous family of vegetables.

      I eat the Asian diet..no gluten/dairy/soy/sugar/GMO…eat meat/veg/rice/nuts open shells to avoid hidden gluten and tea. I eat low sugar fruit like lemon/lime etc.

      See my other comments…and long ones. Best wishes.

  • TS

    Also, I am only 26 ! 🙁

  • Jeannine

    Why is there so much focus about the symptom ‘hypothyroidism’ rather than the actual real issue? 99% of hypothyroidism is caused by an autoimmune condition called Hashimoto’s. It’s not all cookie cutter! But I do know most of the time it’s triggered by stress. Studies and information should be focused more on the immune aspect of this disease. I eat a plant based diet and have reduced my medication AND lost 80lbs. I don’t supplement with iodine or eat any sea vegetables. Sometime iodine can is like adding FUEL TO THE FIRE for hypothyroidism. I eat a lot of the vegetables above.

    • angela

      Hashimoto’s is considered to be an uncurable disease, it also is not always present with individuals with thyroid problems. If you suffer from thyroid issues and things like synthyroid and iodine supplementing, magnesium, and vitamin D3 or adrenal disease are things you have fixated on, and none of them helped you may want to look into Wilson’s syndrome not to be confused with Wilson’s disease. Also the symptoms of hypothyroidism mimic many other illnesses, not to mention if you’ve gone without treatment, could have caused more issues such as fibremyalgia, hyperglycemia, diabetes or insulin resistance, chronic fatigue syndrom, IBS… It is so complicated trying to figure out what exactly is wrong, and the second you walk thru your doctors office they already wrote a prescription. Always seek alternatives once you can pinpoint what is causing your body issues.

      • Wendy Allen

        Celiac may cause low thyroid and other health issues you mention. See my other comments. Best wishes.

    • Erin

      The reason there is so much FOCUS on the SX’s is because this is what tears us down and with each chemical placed into our bodies, a new/different sx/side effect appears from the (hypo)thyroid. Everyone’s thyroid condition IS very different and you may be more lucky than others (count your blessings). Doesnt matter how much of the “immune aspect we focus on, it IS being discussed & sometimes iodine does help, sometimes it doesnt-we all know that. Glad you eat your veggies, I’m sure most of us do but everyone has different reactions. It may be affecting the thyroid. No one really knows unless they try it (restrictiong their diet) out for a few weeks.

    • Wendy Allen

      Stress lowers B vitamins and zinc. Zinc/Se/enough iron/probiotic are needed to convert T4 to T3. Stress makes cortisol that blocks thyroid. Gluten can make antibodies to the thyroid. 97% of the reason for low thyroid is due to gluten. See my other comments. Best wishes.

  • angela

    You forgot to mention strawberries and peaches, I believe there are a lot more negatively affecting foods you left out. Some which cause the thyroid to become inflamed or inflammation over your body. It seems to be my conclusion that most doctors do not wish to help people cure hypothyroidism because that would mean they won’t be purchasing their lifelong sentence or prescriptions such as synthyroid. Think about it, all doctors seem to do is put a temporary fixer into play, never once considering the other problems these prescriptions might cause. I know my father was on a ton of meds for type 2 diabetes, he past away last Tuesday, from pneumonia, his kidneys were failing him, his lungs collapsing. Isht if you had any clue how responsible he was about his medications one would think he should of lived 100yrs, certainly making it to 70, but that’s not the case and you know what, it’s because you can’t rely on doctors today. People have to be smart and willing to read for themselves.

    • frogandprincess

      TOTALLY AGREE!

    • Wendy Allen

      Yes… Type 2 Diabetes/low thyroid can be due to gluten. GMO corn may also hurt people. See my other comments. I agree…People may not get the real help they need unless they go to an Alternative doctor. Best wishes.

  • TexasOlTimer

    I spent the first 67 years of my life never having to worry about gaining weight. I’m short, wore a size 10 and in spite of having myasthenia gravis since my early 40s, got along well with an active (although interspersed with a lot of rest) life. Then I started gaining weight and for the first time in my life tried diets for a year without success. Four years ago a hypothyroid test resulted in the answer. The synthetic forms of thyroid did not help and I’m on natural thyroid. The weight gain has not gone away although many of the other symptoms did.

    I eat foods as all natural and organic as possible. I cook from scratch and avoid foods with chemicals. I’m allergic to corn, cheese and have found that I now need to avoid gluten. Leaving these out of the diet along with the foods recommended not to eat, staying within the calorie count, and exercising as much as possible, the weight only goes up. I take vitamins to help with foods that I cannot chew or swallow due to the weakened jaw and tongue muscles.

    Unfortunately medicare does not cover new clothes and the closet full of size 10 are hanging useless as I have to purchase larger and larger sizes. The extra weight means the muscles weaken more easily, creating a greater problem for exercising. It’s basically a catch-22 situation. Have you any suggestions?

    • Wendy Allen

      Zinc/Se/enough iron/probiotic may convert T4 to T3 for energy/help cells work. Corn may be GMO. Gluten can make antibodies to the thyroid. Gluten maybe hidden in many things..see the internet for a list. Sunlight making Vit D in skin may help. Best wishes.

      Goodwill/garage sales if you need more clothes.

    Thank you very much for this very informative article concerning goitrogens. I’ve done a bit of research concerning thyroid function relating to vegetables and your article has been by far the most interesting, humorous and helpful.

  • Just discovering your site as I am on a mission to not be bound by a drug, when the drug isn’t consistently helping. I found a very concise “what you should eat” list to boost your thyroid. It will be helpful for me for shopping at the market until I learn the food list by heart. Hope it helps someone else too. http://www.lowthyroiddiet.com/foods-to-eat.htm

  • Andrea

    Great article. Very informative. Explains well the complexity of the hypothyroidism. Although my levels are normal, i believe, like many others, I might eventual develop this problem if not careful, as I favour many of the foods mentioned that interfere with thyroid hormone.

  • Seymour Buts

    Sorry but this post is moronic. The VAST majority of the human population that has ever existed has maintained a mostly plant based diet. I am not anti meat, but the way you are anti vegetable is flat out ignoring the entire history of humanity. The only reason Americans are able to eat as much meat as they do is because it is subsidized by the US government.

    • Auggiedoggy

      Exactly! My diet is about 90% plants with the remaining 10% coming from animal flesh of varying types. The healthiest, longest-lived human populations were neither low carb nor vegan/vegetarian.

    Dear Dr. Ede
    I am a 43 year old male, I have a hyperthyroid. I am a chef with an abundant of food to my availability. I am trying to balance my diet. But I keep loosing weight, about 38 lbs in 8 weeks. I was a little over weight, before it happened. Now my clothes don’t fit. I have been seeing doctors. They want to Kill my Thyroid with radiated Iodine. I am not sure if this is the best option. Knowing that you can not give medical advise, I have thought about my questions.
    1st, is it possible to control a hyperthyroid with a change in diet?
    2 can my thyroid correct itself?
    3 are there types of beans that are a good source of protein, and is that source of protein a source that will help

    • Wendy Allen

      Hi, Hyper thyroid may change to low thyroid eventually..burn out. Hyper or low thyroid can be due to eating gluten. Celiac or Paleo diet may help. Ca/Mg and non GMO soy may block thyroid. Most soy maybe GMO. Eating foods that block thyroid may help, but no gluten may stop the root cause. Best wishes.

      No gluten/dairy/soy/sugar/GMO and vitamins/good oils, LDN and detoxing help me. Vit D3 5000IU, zinc 50mg, fish oil 2000mg, 20000mg of evening primrose oil. 2000mg of lecithin, krill oil, coenzyme Q10, rhodiola, Mg citrate 4000mg, Vit C, 5000mcg of biotin, Nature’s Plus- Source of life multiple, HCl and enzymes with meals, dairy free probiotic, Vit B12 methylcobalamin shot/spray/under the tongue kind/intrinsic factor kind, MTHF folate, coenyzme Q10, rhodiola, may help brain/body/depression/cancer and more health issues.

    I have been taking synthroid for several years as prescribed by my Physician. When the dosage was increased about a year ago, I began having difficulty “Dysphonia” , difficulty speaking. I am concerned that this is symptomatic of too much medication? Also ,I tend to love and eat all of the vegetables that seem to be contraindicated when having thyroid issues. Has anyone else experienced vocal cord issues when treating a thyroid condition? Thank you for any feedback.

    • Wendy Allen

      Just cook the vegetables in the cruciferous family. Too much Synthroid may not help…may not convert from T4 to T3. Zinc/Se/enough iron/probiotic may help convert T4 to T3. Synthroid/Amour combo may help. See my other long comments. Best wishes.

    Hello Dr Ede,
    I am so glad to have found this site. I have been on a vegetarian diet for more than ten years, and have been experiencing a host of problems from tachycardia to shortness of breath. Since the heart tests have come out clear and the doctors haven’t been able to diagnose the problem, I was wondering whether the problem could be with the diet. Since a veg diet has traditionally been considered healthy, I am happy to come across this site which gives me a different perspective and could be of help to me. Thank you very much.

    • Wendy Allen

      See the Mercola site…many people said they had to stop vegetarian. Meat may help make muscle that burns fat and gives energy. Gluten may make antibodies to the thyroid. Some people eat too much gluten when vegetarian. Gluten is wheat/barley/rye..oats. Mg citrate may help heart beat and coenzyme Q10. You maybe too low in protein. See my other comments. Best wishes.

  • Ludo N

    A whole foods, vegan diet cured my low thyroid, as well as a list of ailments. I spent some time on a low carb diet in my 20s and that is when I got sick. I am now in my late 30S, 9 years vegan, and I havent felt this good since I was 18.

    • Wendy Allen

      Instead of low carb..need no gluten (wheat/barley/rye/oats) and no GMO corn usually for low thyroid. See my other comments. Best wishes.

    • Wendy Allen

      Gluten may hurt thyroid and pituitary that makes TSH. Zinc/Se/enough iron/probiotic may convert T4 to T3. Eating no gluten/GMO may help. Gluten is wheat/barley/rye..oats or premade food..eat only pure foods and nuts need to open shells to avoid hidden gluten. See my other comments. Best wishes.

  • David

    Hi Dr. Ede,

    Thank you so much for all of the wonderful food information!

    1. I would like to know if Cucumbers and Avocados have thyroid suppressing components.

    2. If so, in roughly what amounts. Eg: small, medium or lots.

    3. Is there anything else about these two foods that would be thyroid suppressant. or cause problems with hypothyroidism.

    I have not been able to find any info about Avocados.

    Cucumbers have flavonoids….. apigenin, a lueolin, a quercetin and a kaempferol.

    Thank you,

    David

  • Snehal Jadhav

    Hello!!

    I m Snehal. I m suffering from hypothyroidism since 8 years, the TSH level is not stable, some time high and sometime low.Now the TSH level is 180 Bcoz of that m gaining weight day by day.

    Can you Please help with Diet plan ?? And Let me know what should i do to bring it to normal level.

    • Wendy Allen

      Gluten/GMO corn may hurt. Gluten may make antibodies to the thyroid..that is why it may change daily depending on what you eat and other foods like soy may block thyroid greatly. Eat pure foods..no American food..no premade food. I eat rice/meat/veg/low sugar fruit/nuts (open shells to avoid hidden gluten)/tea and more. See my other comments. Best wishes.

    • Dear Jonalyn

      I am sorry that I am not able to provide personalized recommendations for any of my readers, only general recommendations in my postings. I am a psychiatrist, so whenever any of my patients have abnormal thyroid hormone tests, I always insist that they see their primary care clinician and/or endocrinologist as well. Hypothyroidism is very serious, there are a variety of causes, and a TSH of 78 is very high. It is important to see your doctor right away. There is unfortunately not enough known about diet and hypothyroidism for me to be able to tell you that if you change your diet in a particular way that you will be able to cure your hypothyroidism. Generally speaking, I recommend healthy dietary changes for everyone in addition to medical care. I hope that this posting and reader comments give you some good ideas about which foods to avoid to see if that can help, but please do not rely on diet alone in your situation. I hope you feel better soon.

  • Edgar Barrington

    It is confusing, Sean. 🙂 Really. One day they say coffee is good for the health, the next day, not! They are saying saturated fats are good for you, the next week it is the opposite! My take is that there seems to be some skulduggery going on behind the scenes. Researchers are there to lie with statistics, thanks to funding from lobby groups and gifts, etc what-have-you from companies who want to use research to promote their products. After all is said and done, you’re right – what works for you may not work for me. Also, people who believe these research findings will probably pay for it with their health or lives because nobody will be able to prove someone was affected because of this or that years from now! And, even if they do provide a definite answer (years down the road), it may be too late for many who followed their bad science, at best! I provided the WebMD URL as there are only a few that are reputable, such as them, Harvard, Mayo Clinic, Johns Hopkins, etc. I am tending not to believe anything at all nowadays! 🙂

    • Sean1978

      I agree with you 100%, next year this and that is detrimental and bad for you but this year it’s the in thing! You are right on that par and we agree. Saturated, Unsaturated, Polyunsaturated etc., some will back it with links and studies and so on to prove the other is bad just like dieters on low carb or high carb things, the other is always right in their opinion and they good proof. It is very confusing. I guess just go with what your body seems to tolerate better and listen to it? This is like doctors drugs too you hear about so and so getting pulled later and it’s dangerous or caused side effects but then a new one comes out which is “safer” but gets pulled later down the road too for side effects, so which is which? It is very confusing I agree. I want to believe things and read up on things but later on hear another and it sounds convincing. All this is very confusing and I guess only time will tell?

      • Dear Sean

        So many of us share your frustration with ever-changing nutrition and public health guidelines. While there are many factors that contribute to this problem, my opinion is that the biggest factor is epidemiological studies. For more information, please see my post on this topic at http://www.diagnosisdiet.com/epidemilogical-studies/

        • Sean1978

          I will read on it Dr. Ede. I have read your blogs before and agree with a lot of the stuff you say.

      • Evolution my friend. Suggested reading material “The Paleo Solution” by Robb Wolf, “the Primal Blueprint” by Mark Sission. “Wheat Belly” by Dr William Davis. And although a bit outdated now “protein power” by Michael Eades MD and Mary Dan Eades M.D.

        • Sean1978

          That is true. I have also read some of Gary Taubes Stuff and the Art and science of low carb living which is good. Fiber Menace is also a very good read. Wheat Belly was one I read first a few years back, loved the read as well. Protein Power is an older classic, will definitely look into that book since it got so many good ratings and you say it is one to look at.

    • Yeah you’re right there’s all sorts of lying and smudge irie going on… TO show that vegetable oils omega sixes and grains are healthy and saturated fats are bad why because there’s a lot of money TO be made if that’s what people believe. Get people TO believe that all The stuff that makes them sick as healthy and then tell them we don’t know why some people just get sick anyway but here take this medication get better O now you’re a customer for life big pharma gets rich doctors get rich and there you have it there’s no money TO be made by keeping people healthy and natural foods. Which is why yes you are correct except your backwards

    • Those 3 are literally the WORST possible sources for nutrition info… lol.

  • cavenewt

    OK, I just read all the comments and this was not mentioned anywhere. I read recently that iodine is volatile. Most of us have that familiar blue carton of Morton salt, and it’s in the cupboard for months and years before being used up. Way before that time, the iodine is long gone.

    Unfortunately I can’t exactly remember the source of this information, but you might want to check into it.

    For myself, I switched to mined sea salt, rich in minerals, a couple of years ago; for the iodine, I sprinkle dulse flakes (a type of seaweed whose package says 1 tablespoon provides 330% of the US RDA) onto my salad several times a week.

    I used to suffer from hypothyroidism for about 10 years so I have tried every treatment & supplement there is. Unfortunately nothing had any positive effect at all on me but after countless online research & trial/error I was actually able to completely cure my hypothyroidism. Here is what worked for me:

    1. Take thyroid hormone supplements. I would suggest speaking to your doctor about which ones exactly as they vary in countries but they offer great initial help.

    2. Follow every step in the free video & guide seen at the following link:

    curehealthproblem*com/hypothyroidism (obviously change the * for a dot as it won’t let me post links here). This will tackle hypothyroidism in a natural way. This is very important.

    3. Take up one of the following: tai chi, yoga or meditation. Not only will it show benefit through exercise but it will improve mental state.

    Try those two steps and hopefully you will get as much luck with getting rid of hypothyroidism as i did. Another final tip is to up the protein in your diet. Just remember it does not have to be a permanent problem, medications may slightly ease symptoms occasionally but you really need to tackle the root cause. Good luck! xoxoxo

    One of the things that helped relieve my hypothyroidism wan to increase my protein consumption.
    Protein transports thyroid hormone to all your tissues. Eating a bit of protein with every meal can help normalize thyroid function.
    You can get protein from nut and nut butters, quinoa, legumes, and hormone and antibiotic-free animal products.
    Here is an article I came across with more tips to help you out with hypothyroidism:

    I was a vegan for 30 years and then got hypothyroidism. Had to go back on a diet eating beef and chicken, eggs because I was so sick and it helped amazingly. Got diagnosed by a top doctor as having Hashimotos. I am on NDT and finally regulated and off of Synthroid for /2 years I got my life back. Gluten free will NOT reduce your antibodies unless…..

    There are Only 3 Science-Backed Reasons for Some People to Avoid
    Gluten

    There are three conditions where people generally need to be on a
    gluten-free diet:

    Celiac disease
    Wheat allergy
    Gluten sensitivity

    THAT IS IT!

    You should find a doctor that knows how to treat your thyroid and do all the required tests. Join the yahoo group naturalthyroidhormones. AND do not go to an ENDO!!! The lower the TSH the better you will feel The higher the TSH means you need hormones.

    And regarding the vegan diet I did not eat vegan junk I made everything from scratch for over 30 years never ate any soy and never ate raw goitrogenic vegetables. You can eat goitrogenic vegies if they are fully cooked not raw that is miss information! Thyroid disease different for every person no 2 people are alike so blanketing cures for every person does not work. Getting a good doctor that understands the thyroid and does not go by TSH, will do all the proper tests and will treat you by symptoms not blood tests is what you need.

    Along with the other important fat-soluble vitamins, D, E, and K, Vitamin A
    acts on the cells of the body like a hormone because it directly affects the DNA
    of the cell nucleus directing cellular protein production. It’s a fancy vitamin
    and has many important functions in your body including reproduction, eye
    function and vision, skin health, immune enhancement, and cellular growth.

    Konnichiwa! I am half Japanese and there are A LOT of foods that are listed that are a main source of my diet. Wasabi, Soy, Chinese cabbage, seaweed, bok choy, etc. are used every day in this household in noodles, Miso soup, stir fry and rice balls wrapped in seaweed (onigiri). I have a hypothyroid and wanted to see what I could do to eliminate this bodily malfunction but…holy cow! I’m gonna starve! Please advise.

    • Konnichiwa to you, Rita!

      It is difficult to let go of foods that we are culturally attached to and love–I know, because I’m part Italian, and can’t eat pasta, bread, or tomatoes anymore:( It could be that your thyroid problem is not related to the foods you mentioned, as some people (particularly people with autoimmune thyroid problems) find that their culprit is gluten. If you haven’t tried gluten-free, that would be a suggestion that might allow you to continue eating some of your favorite foods. If not, you may have to try at least cutting back on some of the foods you listed above and try finding some new foods that are friendlier to your thyroid gland.

    Hi Dr Ede- I struggle with high histamine symptoms (as do you based on some of your other posts). Quercetin is recommended to help lower histamine. Some websites suggested 3-6 grams of supplementation daily. Your post is the first that I have seen that calls out quercetin as a potential problem to the thyroid levels. And some articles have linked thyroid health to histamine intolerance. Curious what your thoughts are with respect to quercetin supplementation in this context.

    • I too used to suffer terribly from all sorts of symptoms of histamines. I had to get weekly allergy injections much of my life. Spring was a time when I couldn’t wear my contacts and typically had to leave the classroom at least once every period to recover from a bout of eye watering, snot flinging sneeze attack. Plus the whole IBS thing…. Basically INFLAMMATION EVERYWHERE!!
      The cause, you ask?

      Why that’s obvious right – allergies – grass etc, duh. Its a unfortunate thing some people deal with as a part of life and that’s just that. Take allergy meds – histamine blockers, and get on with life. — That’s what the makers of Claratin would have you believe at least.

      But it turned out, at least in my case, that that was not the case, not the case indeed. It turns out that allergies don’t have to be a part of life, and neither do the drugs – and their nasty side effects – we take to combat them, or the misery they cause. We are not doomed to suffer! Nor are any meds or supplements required to combat them. I don’t use or recommend taking any supplements (unless someone has a unique medical condition which I can’t manage to fix with food). So what was it then…. if it wasn’t the pollen, wasn’t the dust or pet dander, what was causing my allergies???
      Turns out, IT WAS MY FOOD!!

      I adopted a Paleo diet, focusing on organic meats and veggies plus some fruit, nuts and cheese. I do ok with dairy, not everyone does. I dropped all performance supplements like protein powder, BCAA’s powder, Creatine etc as well.

      Here I am 4 years later, and I never looked back. I no longer get allergy injections, I can leave my contacts in all year with out a thought, sneezes end with 1, maybe 2. No more IBS. Plus the added benefits of no more shin splints, and effortless body composition maintenance around 10% body fat. As a child and teen I had always struggled with my weight. Now I’m a model.

      The moral of the story – Try a strict paleo diet for relief.

    Right in. My wife is a nutritionist and she has gathered all the info from reputable sources to prove, again, that saturated fat is the curse of the human race. People need to wake up and smell reality given all the heart disease and obesiy in western countries. As Fire Marshal Bill says, “When will they learn?”

    • Sean1978

      That’s great, there has been articles and books and studies done on saturated fats as well which prove it is healthy and has health benefits. We disagree there. Your wife is a nutritionist and gathered data on it, guessing the other nutritionists and Doctors who are for it can do the same thing as well to prove their points. Polyunsaturated fatty Acids are the ones that are bad news, the vegetable oils and so on.

      Continue as you will though it’s your opinion and your life and if you are healthy on the diet you are on and enjoy it then continue. I will continue on limiting PUFA and eating Saturated fats and some starches etc., plus cooked veggies. That seems to do do me better. I consider the standard american diet as a whole Russian Roulette and not saturated fats, but that is what I researched and believe and most of all what my body tells me when I eat it which is most important.

      Nowadays you can’t live a squeaky clean life and diet anyways, you just have to do the best you can and if a food fits you personally and you thrive on it go for it, that is all that matters in the end.

    • I’m a nutritionist too. I eat 60% of my calories as fat. Much of it is saturated fat from animal sources. You do realize that fifty percent of your brain matter is composed of saturated fat and cholesterol and every cell membrane Is composed of saturated fat and cholesterol. These cell membranes get damaged and they need repairing these membranes are very important as they regulate influx and e flux of ions into and out of cells. It is vitally important TO maintain electrolyte balance Andy cell membrane plays a large role in this process. When saturated fat are removed from the diet and replaced with man-made fats like the vegetable oil you recommend this changes the osmolarity of the cell member and it does not act the same way that a natural cell membrane would. This causes all sorts of problems not only that but just as if you leave vegetable oil out in the open it will go rancid well it goes rancid in your body as well it oxidizes. Not only that now The body is forced TO use a natural substrates TO manufacture it so member ends so everything is thrown off. Saturated fats are actually vital TO human health vital TO human health. I need at least 30 maybe 40% of my calories from saturated fax my blood Work is impeccable. I have people of every age Group eating that same diet they all get off medication lose weight feel better get stronger every time it’s really pretty simple

    I have suffered from hypothyroidism – very, very bad for a long time. First off, as well, WE ARE ALL DIFFERENT. I cannot eat any cruciferous plants/veggies because it makes my thyroid enlarge and gives me anxiety, among many other bad side effects. It doesn’t matter raw, cooked or steamed. I just avoid them. And as far as iodine goes, this article can’t be further from the truth – if only supplementing once in a lifetime for iodine is why people are developing cancer and dropping dead left and right. I supplement iodine everyday well over 2mg a day, sometimes maybe 10mg. What I tought were ‘side effects’ when I started taking were not. They were simply toxic symptoms because now I am fine.

    A point worth mentioning is that Dr. Ede is of a Psychiatric background and not a medical doctor MD (Endocrinologist or family practice). But her article is information and thought provoking.
