Hypothyroidism Medication: Conventional doctors almost always put their patients on either Synthroid® (a synthetic thyroid hormone pill that contains only T4; sometimes called Levothyroxine, Levothroid, Unithroid, and Tirosint) or Armour (Natural Desiccated Thyroid derived from the thyroid glands of pigs). Both are tablets that patients will have to take daily for the rest of their lives. In some cases, these medications might help, but there are all kinds of side effects and issues that arise. So I recommend two other medications over these two instead.
Although I’m a fan of getting what you need from real food whenever possible, herbs, supplements, and vitamins can still have a place in the thyroid diet plan. It’s hard to give tips here as many people over-medicate and only feel worse later. Hopefully these tips will help; they apply to most auto-immune conditions (This advice was given by my naturopath who focuses on hormonal and thyroid health.):
Goitrogens are substances found naturally in certain foods that can slow down the production of thyroid hormone—keep in mind, though, this phenomenon occurs typically in people with an underlying iodine deficiency (which is rare in the United States). Still, even for people without iodine deficiency, experts recommend not over-consuming goitrogenic foods.
Almost 5 percent of the U.S. population over the age of 12 has some form of hypothyroidism. (1) Some estimates suggest up to 40 percent of the population suffers from at least some level of underactive thyroid. Women — especially older women — are the most susceptible group for developing hypothyroidism. People who are elderly or who have other existing autoimmune diseases — like type 1 diabetes, rheumatoid arthritis and celiac disease, for example — are also at a higher risk.
It’s important to note that there are different types of strains of probiotics. The health effects experienced by one probiotic may be completely different from the health benefits seen from another probiotic.Certain strains of probiotics support a healthy immune system.Others are great for digestion. That’s why it’s important to pick the right probiotic for your needs. It’s also wise to consume a wide range of probiotics in your food or supplements so that you’re covered. The more, the merrier.
The development of TSH assays led to a dramatic reduction in thyroid hormone replacement dosage and the ability to diagnose with certainty milder forms of hypothyroidism. Discovery of peripheral T4-to-T3 conversion gave a physiologic means to justify l-thyroxine monotherapy. In combination with the concerns over consistency and safety of natural thyroid preparations, synthetic l-thyroxine was perceived as a more reliable therapy. These findings laid the foundation for the clinical practice trend away from natural thyroid preparations and toward l-thyroxine monotherapy at doses to normalize the serum TSH. Later, a subpopulation of patients with residual symptoms of hypothyroidism was recognized. It remains to be determined whether this is due to a trend of attributing nonspecific symptoms to minimal thyroid dysfunction, relatively low serum T3 levels and/or high T4:T3 ratio, or the role of Thr92AlaD2 polymorphism, and whether combination therapy with l-thyroxine plus l-triiodothyronine will be beneficial.
Hypothyroidism is a secondary cause of dyslipidemia, typically manifesting in elevation of low-density lipoprotein and total cholesterol levels. It is clear that treatment resulting in the normalization of the serum TSH is associated with reduction in total cholesterol levels (54), but whether total cholesterol is fully normalized by l-thyroxine monotherapy is less well-defined. An analysis of 18 studies on the effect of thyroid hormone replacement on total cholesterol levels in overt hypothyroidism showed a reduction in the total cholesterol level in all 18 studies; however, in 14 of the 18 studies, the mean post treatment total cholesterol level remained above the normal range (>200 mg/dL [>5.18 mmol/L]) (55). These findings suggest that lipid measures are not fully restored despite normalization of the serum TSH (56). Whether the degree of dyslipidemia remaining in l-thyroxine-treated patients with a normal TSH is clinically significant is unknown, given that the benefit of thyroid hormone replacement in subclinical hypothyroidism is itself controversial (57, 58).
The first step in treatment of hypothyroidism is to eliminate the effects and causes of the thyroid dysfunction, such as inflammation, overuse of medications, nutrient deficiencies, and changes in hormones due to stress. The hypothyroidism diet eliminates foods that can cause inflammation and immune reactions and instead focuses on foods that help heal the GI tract, balance hormones, and reduce inflammation.
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.
Hypothyroidism diet tips: Some foods, especially cruciferous vegetables (cabbage, kale, Brussels sprouts, broccoli, and cauliflower) contain natural goitrogens, compounds that can cause the thyroid gland to enlarge by interfering with thyroid hormone synthesis. Cooking has been reported to inactivate this effect in Brussels sprouts. Cassava, a starchy root that is the source of tapioca, can also have this effect. Other goitrogens include corn, sweet potatoes, lima beans, and soy. Some practitioners recommend that people with under-active thyroid glands avoid these foods, even though most have not been proved to cause hypothyroidism in humans.
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
“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]
The best diet for your thyroid requires more than just iodine, selenium, and vitamin D, says Ilic. And—perhaps unsurprisingly—foods that are high in antioxidants are also good for your thyroid. One 2008 study by researchers from Turkey suggests that people with hypothyroidism have higher levels of harmful free radicals than those without the condition.
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.
The normal values for the serum T4:T3 ratio are seldom discussed in the literature because measurement of serum T3 levels is not a recommended outcome in hypothyroidism (1). In a large study of approximately 3800 healthy individuals (4), the serum free T4:free T3 ratio was around 3, as opposed to a ratio of 4 in more than 1800 patients who had undergone thyroidectomy and were receiving l-thyroxine monotherapy. The corresponding serum free T4:free T3 ratio in patients continuing to receive desiccated thyroid is not well-defined, but the serum total T4:T3 ratio is known to be low (28, 50). In one study, the serum total T4:total T3 was about 40 in patients receiving desiccated thyroid and about 100 in those taking l-thyroxine monotherapy (60). Of course, this is affected by the timing of blood collection in relation to the timing of l-triiodothyronine administration, which is not commonly reported. Other key factors are the well-known poor reproducibility of the serum total T3 assay (61) and the interferences with direct measurement of free T3 (5).
Other noticeable effects of hypothyroidism include moodiness and a sluggish metabolism. Essentially when your thyroid is underactive your metabolism will slow down, which might mean you always feel tired or struggle to keep off weight. Your mood is especially susceptible to changes in hormone levels, so some people with hypothyroidism wind up dealing with depression, anxiety, trouble getting good sleep, and low immunity. The thyroid gland helps regulate chemical messengers called neurotransmitters that control your emotions and nerve signaling, which is the reason an out-of-balance thyroid can mean drastic emotional changes at times.
The amount in broccoli, cabbage, and kale in a usual diet is considered of minimal risk. For example, there was no adverse effect on thyroid function from consuming five ounces of cooked Brussels sprouts every day for four weeks.5,6 One note of caution, if you have a thyroid disorder, it's important to realize that juicing concentrates the amount of thiocyanate, on the order of 2000 mcg per glass.7
I think most people with hypothyroidism would agree that their condition is not due to a deficiency of synthetic thyroid hormone. Even though this is obviously true, most endocrinologists tell just about all of their patients with hypothyroidism and Hashimoto’s Thyroiditis to take synthetic thyroid hormone medication for the rest of their life without trying to find out why the person developed a hypothyroid condition to begin with. Although some people do need to take synthetic or natural thyroid hormone on a permanent basis, many people can have their health restored back to normal through natural hypothyroid treatment methods.
Cruciferous vegetables, such as broccoli and cabbage, are full of fiber and other nutrients, but they may interfere with the production of thyroid hormone if you have an iodine deficiency. So if you do, it’s a good idea to limit your intake of Brussels sprouts, cabbage, cauliflower, kale, turnips, and bok choy, because research suggests digesting these vegetables may block the thyroid's ability to utilize iodine, which is essential for normal thyroid function.
