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.
Although the implementation of sensitive TSH assays resulted in dose reduction, it also fueled the discovery of subclinical states of hypothyroidism (i.e., serum TSH <10 mIU/L and normal serum free T4); this state is 20 times more prevalent than overt hypothyroidism (64). Hence, many patients with vague symptoms, such as depressed mood and fatigue, are commonly screened and found to have subclinical hypothyroidism. In many cases, this finding prompts the conclusion that the subclinical hypothyroidism is the cause of the nonspecific symptoms, and thyroid hormone therapy is initiated. The patients in whom the cause–effect relationship was incorrect contribute to the increasing number of euthyroid but symptomatic patients (57). The marked increase in prescribing of thyroid hormone with decreasing TSH thresholds amplifies this problem (47).
To document that this was a result of trends toward lower doses, an unblinded study tracked well-being according to various doses and found that the highest well-being was achieved at supraoptimal doses, resulting in a suppressed TSH (65). However, a blinded trial did not reproduce this finding (66). In a call to the public, a 1997 British Thyroid Foundation newsletter asked readers to recount personal history of residual hypothyroid symptoms. More than 200 patients responded, 54 of whom specifically mentioned that they did not feel well despite normal serum markers of thyroid function (67, 68). Because of this surge in symptomatic patients, some clinicians advocated titrating dose by symptoms rather than serum TSH, reminiscent of the period before the 1970s (69).
“For women who may become pregnant, during pregnancy, or lactating, the American Thyroid Association recommends taking a daily supplement containing 150 mcg of iodine,”8 says Elizabeth Pearce, MD, MSc, professor of medicine at Boston University School of Medicine in Massachusetts, and the ATA also recommends against taking added selenium during pregnancy given some concern that there is an increased risk of developing gestational diabetes.

Many types of seaweed are chockfull of iodine, but the amount can vary wildly, says Mira Ilic, RD, a registered dietician at the Cleveland Clinic. According to the National Institutes of Health, a 1-gram portion can contain anywhere from 11% to a whopping 1,989% of your percent daily value. But since seaweed is especially high in iodine, you shouldn't start eating sushi every day of the week. Too much iodine can be just as harmful to your thyroid as too little by triggering (or worsening) hypothyroidism. To get seaweed's big benefits without going overboard, Cynthia Sass, MPH, RD, and Health's contributing nutrition editor advises sticking to one fresh seaweed salad per week (in addition to sushi), and steering clear of seaweed teas and supplements.
l-Thyroxine monotherapy for athyreotic rats results in a high T4:T3 ratio at doses sufficient to normalize serum TSH levels (8). Yet, the brain, liver, and skeletal muscle tissues of these l-thyroxine–treated animals continue to exhibit markers of hypothyroidism (9), probably because of the inability of l-thyroxine monotherapy to restore tissue levels of T3 (8). This is probably a direct consequence of lower serum T3 levels and the relatively high T4 concentration in these tissues, which inactivates the type 2 iodothyronine deiodinase (D2). In the hypothalamus, loss of D2 is minimal in the presence of T4, which increases sensitivity to T4 levels and explains TSH normalization, despite relatively lower levels of serum T3. Only combination therapy with l-thyroxine plus l-triiodothyronine normalized all thyroid hormone–dependent measures (9), including serum and tissue T3 levels (8). Whether tissue-specific markers of hypothyroidism are restored with l-thyroxine monotherapy in humans remains to be determined, as does the ability of l-thyroxine plus l-triiodothyronine combination therapy to normalize the serum T4:T3 ratio without adverse events. The development of a novel drug delivery system for l-triiodothyronine would facilitate these studies (5).
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.
Stress can also be caused by chronic digestive issues. When the small or large intestine is in distress (ywhen you are always constipated, bloated, suffer from gas, pain, loose stool etc.), the body sees it as a state of stress. Cortisol is a potent hormone we won’t function without. However, when in excess, it can have a detrimental impact on the thyroid and the immune system (one of the functions of cortisol is to modulate the immune system).
Hypothyroidism (low thyroid function) is believed to be one of the most underdiagnosed health conditions in the United States. Many of its symptoms—lethargy, depression and weight gain—can be easily attributed to other factors, making hypothyroidism difficult to diagnose. Some reports estimate that around 15 percent of the population suffers from the condition; other reports estimate more than twice that. Risk increases with age, particularly in menopausal women. Hyperthyroidism (overactive thyroid), the opposite of hypothyroidism, is considerably less common and is characterized by extreme nervousness and restlessness.
If you do choose to eat gluten, be sure to choose whole-grains varieties of bread, pasta, and rice, which are high in fiber and other nutrients and can help improve bowel irregularity, a common symptom of hypothyroidism. Also be sure to take your hypothyroidism medication several hours before or after eating high-fiber foods, to prevent them from interfering with the absorption of your synthetic thyroid hormone.
