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.
You may find that changing your diet will help. One suggestion is to reduce or eliminate sugar, limit fruit, dairy, and grains, and get your carbohydrates mainly from vegetables. Round out your diet with lean proteins and healthy fats. In addition, eating two to three meals a day, no snacks, and avoiding food after 8 p.m. seems to help balance hunger hormones and blood sugar—and promote fat burning.
Probiotic-Rich Foods – These include kefir (a fermented dairy product) or organic goat’s milk yogurt, kimchi, kombucha, natto, sauerkraut and other fermented veggies. Part of your hypothyroidism diet, probiotics help create a healthy gut environment by balancing microflora bacteria, which reduces leaky gut syndrome, nutrient deficiencies, inflammation and autoimmune reactions.
Choose foods that offer nutritional support for your thyroid. The production of thyroid hormones requires iodine and omega-3 fatty acids; converting the inactive T4 to the active T3 requires selenium; and both the binding of T3 to the receptor on the nucleus and switching it on require vitamins A and D, as well as zinc. You will find these nutrients in a whole-food, clean, organic diet. To get therapeutic levels of these nutrients, please use the supplement protocol in strategy 4.
Radioimmunoassays for measurement of serum T3 (48) and T4 (49) were soon developed, and it was observed that l-thyroxine monotherapy could normalize both T4 and T3 levels at the expense of a high T4:T3 ratio. In contrast, l-triiodothyronine, desiccated thyroid, thyroglobulin, and l-thyroxine/l-triiodothyronine combination all typically resulted in low or low-normal serum T4 values with usually elevated serum T3 levels, and thus a low T4:T3 ratio (28). Desiccated thyroid resulted in a T3 peak about 2 to 5 hours after administration that corresponded to thyrotoxic symptoms in some patients (50). That a single daily dose of l-thyroxine resulted in stable blood levels of T4 and T3 throughout the day (48) was understood to result from a steady rate of conversion of T4 to T3 (51).
When the hypothalmus decides we need more thyroid hormone in circulation (cold weather or increased activity level for example) it sends a chemical messenger called thyrotropin-releasing hormone (TRH) which goes to the pituitary gland. The pituitary than sends thyroid stimulating hormone (TSH) over to the thyroid. TSH activates the production of a protein called thyroglobulin.
To offer some perspective: up to 95% of the thyroid hypothyroidism in the US is caused not by an iodine deficiency, but occurs as the result of an autoimmune disease so avoiding cruciferous vegetables will do little to fix your underactive thyroid, and may deprive you of valuable healthy benefits such as dietary fiber, and anti-inflammatory, cancer-fighting antioxidants.5
Apart from conventional medical treatment of hypothyroidism and changing your diet and eating habits, there are also a variety of alternative therapies that could help treat the condition. Physical fitness programs can help cope with the disease. Studies into the effects of yoga on hypothyroidism patients have supported claims of its health benefits, as the practice was found to be useful in the management of disease related symptoms.
A cup of cooked white beans serves up 8mg of iron—a mineral that many people, especially premenopausal women, have trouble getting enough of . But getting your fill is important. “If you don’t, it can impair the activity of enzymes that produce thyroid hormones,” Dr. Lee says. (Women aged 19 to 50 need 18mg iron daily, while men and women 51 and older need 8mg .)
Hypothyroidism can be easily treated with thyroid hormone replacement. The preferred treatment for most people with an underactive thyroid is levothyroxine sodium (Levoxyl, Synthroid). This is a more stable form of thyroid hormone and requires once a day dosing.Liothyronine sodium (Cytomel) also may be prescribed to treat hypothyroidism under certain conditions.
Dietary changes: For those who have existing thyroid conditions, excess consumption of soy may affect thyroid function, but this is probably a concern only in those already taking Synthroid or other thyroid replacement medication. If you consume soy on a regular basis, you may require a slightly increased dosage of replacement therapy. You should also know that if you eat soy foods at the same time that you take thyroid hormone, they may interfere with its absorption. To be safe, do not eat soy within three hours of taking your medication. Moderate soy consumption (one serving daily of whole soy foods) should not be a problem. Adequate iodine from dietary sources is also important – iodized salt, fresh ocean fish and seaweed are good sources.
Over my several decades working as a Functional Medicine doctor, I can assure you that even in the toughest cases, you can heal your thyroid. With some patients, I can do this through the dietary, nutrient, and lifestyle factors I’ve discussed here. For others, that healing requires trial and error using several medications and working closely with a physician.
The vast majority of individuals—one in seven are women—with hypothyroidism in the US have Hashimoto’s thyroiditis, an autoimmune disease in which your body doesn’t produce enough thyroid hormone, but this isn’t caused by iodine levels in the diet.2 Other less common causes of hypothyroidism include a deficiency of iodine in the diet, taking certain medications that interfere with thyroid absorption, surgical removal of the thyroid, and a genetic disorder.
Gluten intolerance is highly associated with inflammatory disorders of all kinds (63). It is also a contributing factor in many autoimmune diseases such as celiac disease, rheumatoid arthritis, type I diabetes, Hashimoto’s thyroiditis, autoimmune cardiomyopathy, lymphoma and dermatitis herpetiformis (skin disease) among others (64, 65). If you have a thyroid problem or just want to avoid having a future thyroid problem, the first place to start is on a gluten-free nutrition program!
Everyone has bacteria in their digestive tract, or gut, that is essential to the function of the human body. A healthy adult has about 1.5 – 2 kg of bacteria in their gut, both good and bad. Normal levels of bacteria, or flora, in the gut protect against invaders, undigested food, toxins, and parasites. When the good and bad bacteria in the gut get out of whack (i.e. more bad than good), a whole host of negative reactions can occur in the body. Undigested foods can leak through into the bloodstream causing food allergies and intolerances, vitamins and minerals may not be absorbed, leading to deficiency, and the bad bacteria can produce a whole host of toxins, leading the immune system to not function properly. An effective thyroid diet includes probiotics that you can get from fermented foods.
Initial strategies for thyroid hormone replacement included thyroid transplantation, but efficacious pharmacologic strategies soon won favor. Natural thyroid preparations containing T4 and T3, such as desiccated thyroid, thyroid extracts, or thyroglobulin, were the initial pharmacologic agents. Synthetic agents were synthesized later. Early clinical trials demonstrated the efficacy of synthetic and natural agents, but concerns arose regarding consistency of natural thyroid preparations and adverse effects associated with T3-containing preparations (natural or synthetic). With the demonstration of peripheral T4-to-T3 conversion and the availability of the serum TSH radioimmunoassay in the early 1970s, there was a major trend in prescribing preference toward l-thyroxine monotherapy. BMR = basal metabolic rate; DT = desiccated thyroid; IV = intravenous; RIA = radioim-munoassay; T3 = triiodothyronine; T4 = thyroxine; TG = thyroglobulin; TSH = thyroid-stimulating hormone.
Moreover, a strong relationship exists between thyroid disorders, impaired glucose control, and diabetes. Thirty percent of people with type 1 diabetes have ATD, and 12.5% of those with type 2 diabetes have thyroid disease compared with a 6.6% prevalence of thyroid disease in the general public. Both hypothyroidism and hyperthyroidism affect carbohydrate metabolism and have a profound effect on glucose control, making close coordination with an endocrinologist vital.8
These individuals very often have intestinal permeability and dysbiosis so the heavy proteins can be challenging on their digestive system. Eggs are also one that many people in this category have a sensitivity too. I get them doing just small amounts of proteins and loading up on anti-oxidant rich vegetables and herbs and good fats like coconut oil/butter, etc.
Thyroid surgery - Thyroid surgery may be performed if a patient is experiencing hyperthyroidism, goiters, thyroid nodules, or thyroid cancer. Thyroid surgery involves removing either all of the thyroid or a large portion of the thyroid gland, both of which diminish and/or halt thyroid hormone production. In this case, hypothyroidism will be a lifelong condition and the patient will need to take a supplemental thyroid hormone for the rest of their life.
Medication is the first option as treatment for hypothyroidism. Doctors may prescribe different medications to bring the production of thyroid hormone to normal levels. However thyroid medications tend to react differently to different people and it may take a while to find the drug that best suits your individual case. In the meantime, you can also try some natural remedies for hypothyroidism. Always make it a point to keep your doctor in the loop however, as most natural treatments have not been subjected to rigorous testing and some could in fact have an adverse effect or interfere with the action of medications. The use of exercise and supplements is thought to help in the natural treatment of hypothyroidism. Including an hour of exercise at least thrice a week is important for the treatment of hypothyroidism. In addition to this, you can speak to your doctor about what supplements you should be having along with the proper dosages.
Whether you take these minerals in a multivitamin or alone, calcium and iron supplements may counteract the medication you take to treat your underactive thyroid. These supplements may affect your ability to absorb levothyroxine, the synthetic thyroid hormone found in medications such as Synthroid and Levothroid, according to the Mayo Clinic. “There’s a very strict way to take thyroid medication,” Blum says. You take it the same way every day, at least one hour before food and never with calcium, iron or other minerals. Blum recommends taking your thyroid medication as soon as you wake up and consuming the mineral supplements with food at dinnertime or before bed.
Every three months, you will repeat this process. This repetition is to ensure that you are staying healthy and that the medication is working. As you approach the end of your 90-day prescription, we'll order new lab tests and book a quick check-in with your doctor to make sure that the treatment plan is working for you. If you have any questions in the meantime, you can always give PlushCare a call at 1-888-529-3472, where our Care Coordinators are ready and willing to assist you.
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 realize that the malfunctioning thyroid gland is usually not the primary cause of their condition. After all, one’s thyroid gland doesn’t just stop producing thyroid hormone on its own, as there is always a cause behind this. So while giving thyroid hormone may do a good job of managing one’s symptoms (although this isn’t always the case), it is not doing anything for the cause of your condition.
A pituitary injury may result after brain surgery or the blood supply to the brain has decreased. When the pituitary gland is injured, hypothyroidism results in low TSH blood levels because the thyroid gland is no longer stimulated by the pituitary TSH. Usually, hypothyroidism from pituitary gland injury occurs in together with other hormone deficiencies, since the pituitary regulates other processes such as growth, reproduction, and adrenal function.
Studies have indicated that individuals with lower selenium levels are at higher risk for low T3 (50). Selenium has been shown to reduce rT3 levels and improve active T3 status (51). It also reduces anti-thyroid anti-body formation (52). Be sure to get selenomethionine which is the most effective form of selenium for reducing anti-body formation and improving thyroid function.
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:
Before birth, a baby depends on the mother for thyroid hormones until the baby's own thyroid gland can start to function. Usually, this occurs after about 12 weeks of gestation or the end of the first trimester of pregnancy. Moreover, babies of mothers who had an underactive thyroid in the first part of their pregnancy who then were treated, exhibited slower motor development than the babies of normal mothers.
Selenium: Selenium is one the MOST IMPORTANT when it comes to healthy thyroid function! It is incorporated into key enzymes involved in several metabolic pathways implicated in thyroid hormone metabolism; additionally, it plays an antioxidant role in the regulation of the immune system. There are strong links between selenium deficiencies and auto-immune thyroid problems (48, 49).
You’ve probably heard this complaint time and again from clients who have thyroid disease—and with good reason. To the great frustration of many of the 27 million Americans with thyroid gland issues, the thyroid has a profound impact on metabolism. Unintended weight gain and weight loss are common, and both can be a daunting challenge to rectify. Although weight may be the most common complaint, clients are at an increased risk of cardiovascular disease and diabetes, underscoring the need to eat a balanced diet and adopt a healthful lifestyle. But since one-half of all people with thyroid disease are undiagnosed and weight changes are a common symptom,1 RDs are in a prime position to spot potential thyroid conditions, make appropriate referrals, and help clients get a timely diagnosis and the treatment they need.
Sprouted Seeds — Flax, hemp and chia seeds provide ALA, a type of omega-3 fat that’s critical for proper hormonal balance and thyroid function. Adequate levels of fats in your hypothyroidism diet support a healthy mood and brain function while helping to lower inflammation. Eating plenty of healthy fats also stabilizes blood sugar levels and can help you stay at a healthy weight.
Having a thyroid condition is no picnic, but you're not alone with this health issue. According to the American Thyroid Association, more than 12 percent of the population may end up dealing with a thyroid condition at some point in their lives. And thyroid issues can be sneaky: Of the nearly 20 million Americans living with the disease, as many as 60 percent don't even realize they have it.
