Emphasizing lean proteins, vegetables, fruits, heart-healthy fats and omega-3s, high-fiber foods, and appropriate portions can help manage or prevent illnesses associated with thyroid disease. As Schneider notes, “It’s eating for prevention of all these diseases that accompany thyroid disease: heart disease, diabetes, cancer, and more.” As an added bonus, fiber can relieve constipation that people with hypothyroidism often experience.
From the early 1890s through the mid-1970s, desiccated thyroid was the preferred form of therapy for hypothyroidism (Appendix Table, available at www.annals.org). This preference was reinforced by the unique ability of desiccated thyroid to reproduce a normal serum PBI (33). The predominance of natural thyroid products was illustrated by prescribing patterns in the United States: In 1965, approximately 4 of every 5 prescriptions for thyroid hormone were for natural thyroid preparations (38). Concerns about inconsistencies in the potency of these tablets arose (26) after the discovery that some contained anywhere from double to no detectable metabolic activity (39). The shelf-life of desiccated tablets was limited, especially if the tablets were kept in humid conditions (36). There were reports of patients not responding to desiccated thyroid altogether because their tablets contained no active thyroid hormone. It was not until 1985 that the revision of the U.S. Pharmacopeia standard from iodine content to T3/thyroxine (T4) content resulted in stable potency (38), but by then the reputation of natural thyroid products was tarnished (40).
l-Thyroxine was the first synthetic molecule used to treat hypothyroidism (23) and was shown to be efficacious as monotherapy for myxedema (24). Around that time, serum protein-bound iodine (PBI) emerged as a diagnostic test and therapeutic marker; serum PBI quantitation was the only valid way to biochemically assess thyroid hormone status (25). This tool was limited in terms of treatment monitoring because the effect on serum PBI varied by agent (26). For example, l-triiodothyronine corrected BMR without much increase in serum PBI, l-thyroxine increased serum PBI sometimes to above normal, and combination l-thyroxine and l-triiodothyronine and desiccated thyroid had the advantage of normalizing serum PBI (27). In addition to BMR and serum PBI, other surrogates for treatment response included cholesterol levels, symptoms, and deep tendon reflexes, but their lack of sensitivity was always recognized (28).
Most people with hypothyroidism don’t need to steer clear of soy completely. But it’s a good idea to limit your consumption to a few servings a week, and to stick with minimally processed forms of soy like tempeh or miso. Foods containing processed soy protein isolates (like soy protein powder, soy protein bars, or soy-based meat analogs) tend to have a higher concentration of isoflavones, says Markley.
There are also certain risk factors for hypothyroidism including radioactive iodine or anti-thyroid medications for hyperthyroidism, lithium, Congenital disease or tumors on your pituitary gland, pregnancy, miscarriage, premature delivery and/or preeclampsia, Iodine deficiency, autoimmune disease, enlarged thyroid glands or goiters, and high levels of low-density lipoprotein (LDL) cholesterol.
The thyroid is the organ with the highest selenium content in the whole body. Selenium is necessary for the production of the T3 thyroid hormone and can reduce autoimmune affects. In patients with Hashimoto’s disease and in pregnant women with thyroid disturbances, selenium supplementation decreases anti-thyroid antibody levels and improves the structure of the thyroid gland.
The thyroid gland uses iodine (mostly from foods in the diet like seafood, bread, and salt) to produce thyroid hormones. The two most important thyroid hormones are thyroxine (tetraiodothyronine or T4) and tri-iodothyronine (T3), which account for 99% and 1% of thyroid hormones present in the blood respectively. However, the hormone with the most biological activity is T3. Once released from the thyroid gland into the blood, a large amount of T4 is converted as needed into T3 - the active hormone that affects the metabolism of cells.
People with celiac disease—the autoimmune disease that's characterized by an intolerance to the gluten in wheat, barley, and rye—are also more likely to have higher rates of thyroid problems, according to a 2007 report by researchers in the United Kingdom. "Eating a gluten-free diet helps control the symptoms, which may also help protect the thyroid gland," says Ilic. But unless you have celiac disease—and we're not talking an L.A.-aversion to gluten, here — you might not want to avoid breads after all. In fact, thanks to some of the baking processes, bread can actually contain some iodine.
Characteristic symptoms and physical signs, which can be detected by a physician, can signal hypothyroidism. However, the condition may develop so slowly that many patients do not realize that their body has changed, so it is critically important to perform diagnostic laboratory tests to confirm the diagnosis and to determine the cause of hypothyroidism. A primary care physician may make the diagnosis of hypothyroidism, but assistance is often needed from an endocrinologist, a physician who is a specialist in thyroid diseases.
Certainly, many of the foods listed above are an important part of a healthy diet. Try to eat a varied diet so that you avoid eating large amounts of goitrogenic foods on any one day. Be especially careful about raw juicing, which can concentrate these foods. Cooking, steaming, and even blanching (such as with kale) reduce goitrogen content and are good options when you wish to consume these foods.
As hypothyroidism becomes more severe, signs and symptoms may include puffiness around the eyes, the heart rate slows, body temperature drops, and heart failure. Severe hypothyroidism may lead to a life-threatening coma (myxedema coma). In a person with severe hypothyroidism, a myxedema coma tends to be triggered by severe illness, surgery, stress, or traumatic injury. Myxedema coma requires hospitalization and immediate treatment with thyroid hormones given by injection.
When a patient is suspected to have a thyroid disorder a comprehensive thyroid profile is ordered, in the form of a blood test. The test results will give precise measurements of Free T3 and T4 and their ratios to each other. If the results indicate that for example, the patient’s T3 level is too low then the patient will be checked for deficiencies in essential nutrients which are required for hormone production. Many times this will correct the thyroid without the need for prescription hormones.
If you are diagnosed with hypothyroidism, it may sound horrible, but you could be in it for life. This means you'll need to change your diet and lifestyle entirely. There must be a conscious and consistent plan for your everyday intake of food to prevent flares of symptoms that could disrupt your everyday routine. If you adhere strongly to your diet plan, then there shouldn't be any worries about symptom attacks later on.
A diet low in nutrient-rich foods, especially in iodine and selenium (which are trace minerals crucial for thyroid function), increases the risk for thyroid disorders. The thyroid gland needs both selenium and iodine to produce adequate levels of thyroid hormones. And these nutrients also have other protective roles in the body; for example, severe selenium deficiency increases the incidence of thyroiditis because it stops activity of a very powerful antioxidant known as glutathione which normally controls inflammation and fights oxidative stress.
Thyroid hormones regulate cholesterol synthesis, cholesterol receptors, and the rate of cholesterol degradation. Hypothyroidism increases LDL levels, and increased cholesterol levels have been shown to induce hypothyroidism in animal models. Normalization of thyroid hormone levels has a beneficial effect on cholesterol, which may be worth noting especially for clients who choose not to take prescribed thyroid medications.7
It is medically proven that small frequent meals are healthier for persons with hypothyroidism compared to eating large-bulky meals per day. A study showed that eating 5-6 small meals a day will help a person lose weight and ward off the symptoms of the disease. It does not only help your intestines to digest food, it also keeps your energy level up.
Dry skin (xeroderma) may be caused by external factors, like cold temperatures, low humidity, harsh soaps, and certain medications, or internal factors, such as thyroid disease, diabetes, psoriasis, or Sjogren's syndrome. Symptoms and signs of dry skin include itching and red, cracked or flaky skin. The main treatment for dry skin is frequent, daily lubrication of the skin.

Hypothyroidism is a disorder caused due to inadequate production of thyroid hormone, in comparison to the normal body requirements. In this condition, the thyroid gland is said to be 'underactive'. Insufficient thyroid hormone results into slowing down of the overall body metabolism. Hypothyroidism affects both men and women, but women are eight times more susceptible. People of all ages can be affected by this disorder and over 5 million Americans have this disorder. Hypothyroid people are susceptible to cancers, heart disorders, and infections. Severe hypothyroidism in adults is called 'Myxedema' and in children it is called 'Cretinism'.
The omega-3 fatty acids found in fatty fish such as wild salmon, trout, tuna, or sardines make this food an excellent choice for lunch or dinner, says Virginia Turner, MS, RD, LDN, clinical nutrition manager at The University of Tennessee Medical Center in Knoxville. Unmanaged hypothyroidism can increase the risk for heart disease as a result of higher levels of low-density lipoprotein (LDL), the "bad" cholesterol. "Omega-3s are known to decrease inflammation, help with immunity, and lower the risk for heart disease," she adds. Fish is also a good source of the nutrient selenium, which is most concentrated in the thyroid. Selenium also helps decrease inflammation.
A meta-analysis of randomized, placebo-controlled studies has shown benefits of selenium on both thyroid antibody titers and mood in patients with Hashimoto’s, but this effect seems more pronounced in people with a selenium deficiency or insufficiency at the outset.15 Conversely, an excessive intake of selenium can cause gastrointestinal distress or even raise the risk of type 2 diabetes and cancer. So clients will benefit from having their selenium levels tested and incorporating healthful, selenium-rich foods in to their diets, such as Brazil nuts, tuna, crab, and lobster.15
You need to reduce the toxins you ingest from additives, preservatives, artificial sweeteners (!), excessive sodium, and trans-fats and try to eliminate toxins hiding around your house. Water toxicity is a HUGE problem in thyroid conditions. Most public water systems in the US have fluoride added, which is now linked to slowing down the thyroid; fluoride is believed to be leaching on to the thyroid cells inhibiting the uptake of iodine, hence the altered production of the thyroid hormone (T4).
The symptoms of hypothyroidism are often subtle. They are not specific (which means they can mimic the symptoms of many other conditions) and are often attributed to aging. People with mild hypothyroidism may have no signs or symptoms. The symptoms generally become more obvious as the condition worsens and the majority of these complaints are related to a metabolic slowing of the body. Common symptoms and signs include:
In developing countries, insufficient amounts of iodine in the diet account for most cases of hypothyroidism. Iodine is necessary for the production of the two main thyroid hormones, thyroxine (T-4) and triiodothyronine (T-3). In the U.S. – where salt is iodized, and most Americans get plenty of iodine from table salt – an autoimmune condition known as Hashimoto’s thyroiditis is the most common cause. Hashimoto’s is more common in women and in those with a family history of autoimmune diseases. It involves immune-related inflammation and destruction of the thyroid gland, which reduces proper functioning and production of thyroid hormone. The exact cause and triggers of Hashimoto’s still remains unknown.
Central or pituitary hypothyroidism: TSH (Thyroid-stimulating hormone) is produced by the pituitary gland, which is located behind the nose at the base of the brain. Any destructive disease of the pituitary gland or hypothalamus, which sits just above the pituitary gland, may cause damage to the cells that secrete TSH, which stimulates the thyroid to produce normal amounts of thyroid hormone. This is a very rare cause of hypothyroidism.
The development of TSH radioimmunoassay (43) provided the first sensitive and specific marker of systemic thyroid hormone status (Figure). Clinicians could now titrate therapy to achieve a serum TSH within the normal range as a specific marker of replacement adequacy (44). For patients who were once treated with doses that normalized their symptoms, BMR, or serum PBI, the use of serum TSH revealed such doses to be typically supratherapeutic (45, 46). Maintenance doses of l-thyroxine ranged from 200 to 500 mcg/d before the institution of the TSH assay and then became typically closer to 100 to 150 mcg/d (Appendix Table). Implementation of the TSH radioimmunoassay also provided a means to diagnose much milder, or even subclinical, cases of hypothyroidism that may have been undiagnosed with earlier, less sensitive, diagnostic methods (47).
The purpose of treating hypothyroidism is to maintain normal metabolism by correcting a deficient output of thyroid hormone. Once replacement therapy begins, the thyroid will stop producing hormones all together, and replacement must be continued for life. Most mainstream physicians prescribe the drug Synthroid, also known as levothyroxine, a synthetic analog of thyroxine (T-4) and monitor how much to give based on symptoms and levels of TSH. Physicians will generally check TSH levels after a couple of months of being on the medication and adjust it accordingly. They will often used a more cautious course in patients who have cardiovascular disease. This allows the heart time to adjust to an artificially increased metabolism. Side effects of taking too much thyroid hormone include shakiness, palpitations, insomnia and changes in appetite.
While there is no specific diet regime that hypothyroid patients are supposed to follow, they should make sure that they eat a well-balanced diet full of all the nutrients and vitamins that are required by the body. Doctors suggest that eating too much of any food is going to be harmful to thyroid patients. Hence, a generous mix of nutrient-rich fruits and vegetables are going to be helpful for people suffering from hypothyroidism.
Goitrogens are naturally occurring substances in certain foods that interfere with the production of thyroid hormones (the hormones that people with hypothyroidism lack). They include some of the most commonly consumed foods of the health-conscious community: broccoli, cauliflower, kale, spinach, radishes, soybeans, peanuts, pine nuts, peaches and millet. The good news is that many health professionals believe that cooking may inactivate goitrogens.
Hypothyroidism (overactive thyroid) is a condition in which the thyroid gland produces an abnormally low amount of thyroid hormone. Many disorders result in hypothyroidism, which may directly or indirectly involve the thyroid gland. Because thyroid hormone affects growth, development, and many cellular processes, inadequate thyroid hormone has widespread consequences for the body.
Constipation is a common symptom of hypothyroidism. Whole-grain foods such as cereal, bread, pasta, and rice are high in nutrients in addition to fiber, which can help with bowel regularity. However, fiber can interfere with synthetic thyroid hormones, cautions Turner. Some people with hypothyroidism choose to avoid whole-grains altogether, but if you do choose to eat them, "the recommendation is to take your thyroid medication several hours before or after eating foods rich in dietary fiber," she says.
Diagnosis of hypothyroidism is based on your symptoms and the results of blood tests that measure the level of TSH and sometimes the level of the thyroid hormone thyroxine. A low level of thyroxine and high level of TSH indicate an underactive thyroid. That's because your pituitary produces more TSH in an effort to stimulate your thyroid gland into producing more thyroid hormone.
“The effects of fluoride on various aspects of endocrine function should be examined, particularly with respect to a possible role in the development of several diseases or mental states in the United States. Major areas of investigation include . . . thyroid disease (especially in light of decreasing iodine intake by the U.S. population).” (National Research Council, 2006)
Most physicians diagnose hypothyroidism by simple blood tests that measure the level of TSH (thyroid stimulating hormone), which is made by the pituitary gland in response to thyroid hormone and the body’s needs, and indicates thyroid status. As levels of thyroid hormones fall, the pituitary releases TSH to stimulate the thyroid to produce more hormone. Clinicians may also measure circulating levels of T-3 and T-4, which are the thyroid hormones themselves. Low levels of T-4 and high levels of TSH reveal an underactive thyroid. Other variants of hypothyroidism can exist. Patients can have no symptoms and normal serum thyroid hormone levels, but elevated TSH. Others can have symptoms, but normal TSH and T-4 levels. Patients with either of these variants may benefit from supplementation. In addition, someone with a temporary illness might have a completely normal thyroid but high TSH, a condition called “sick euthyroid” which usually resolves without any intervention.
I don’t know all your symptoms or health challenges, but if you have thyroid issues and if you are losing hair (alopecia areata?), you may want to consider getting tested for celiac disease. It is quite common for people to have celiac disease and thyroid disease. It’s important not to eliminate gluten from your diet before being tested as it would cause a false-negative test result.
The association between hypothyroidism and energy expenditure was suspected clinically, and the discovery of lower O2 consumption in myxedema provided an early diagnostic tool (19). The development of a device to assess energy expenditure through measurement of the basal metabolic rate (BMR) in humans proved to be useful for not only diagnosis but also titration of therapy (20). The scale was calibrated so that a normal BMR reference range would be around 0%, whereas athyreotic individuals could have a BMR of about −40% (21). Because of lack of specificity (for example, low BMR in malnutrition), BMR was used in conjunction with the overall clinical impression; a low BMR in the setting of high clinical suspicion would secure a diagnosis and justify treatment (21, 22).
T4 circulates through to the liver where 60% of it is converted into T3 through the glucoronination and sulfation pathways. If the liver is sluggish it will cause a problem in T4-T3 conversion (6). Another 20% is converted into reverse T3 which is permanentely inactive. The final 20% is converted into T3 sulfate and T3 acetic acid which can then be further metabolized by healthy gut bacteria to produce more active T3 (6).
The thyroid gland, situated just below the Adams apple on the low part of the neck, produces the thyroid hormones in the body. The thyroid gland is shaped like a butterfly and wraps itself around the trachea with two lobes attached to a central isthmus. When you eat foods containing iodine such as salt and seafood, this thyroid gland uses the idodine to produce the thyroid hormones. There are two important types of thyroid hormones produced which would be T4 or Thyrozine and T3 or Triiodothyronine (T3). These account for most of the thyroid hormones present in the bloodstream. T3 is the more active of the hormones and it affects cellular metabolism.
I wish there were two different words to say what I want to say: one for “diet” as in when you want to lose weight and another “diet” as in a nourishing food change that will bring healing and joy. Oh well… But you know when I say “diet” I mean a protocol, a way of being, a way of living and eating that will free you from some or all of the fatigue, depression, anxiety, weight yo-yo’s, food frustrations, and infertility that have plagued you for some time now. I want to share with you what I know about the best healing diet for thyroid issues.
