Caffeine has been found to block absorption of thyroid hormone replacement, says Dr. Lee. "People who were taking their thyroid medication with their morning coffee had uncontrollable thyroid levels, and we couldn't figure it out," she says. "I now have to be very careful to tell people, 'Only take your medication with water.'" You should wait at least 30 minutes after taking your medication before having a cup of joe.
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.
A discussion on thyroid disease and good health isn’t complete without stressing the importance of physical activity. Lisa Lilienfield, MD, a thyroid disease specialist at the Kaplan Center for Integrative Medicine in McLean, Virginia, and a certified yoga instructor, is a firm believer in the importance of exercise, particularly for clients with a thyroid disorder. “With hypothyroid patients, certainly exercise can help with weight gain, fatigue, and depression. With hyperthyroidism, anxiety and sleep disturbances are so common, and exercise can help regulate both.”
In humans, a factor associated with response to combination therapy in a large clinical trial is the Thr92Ala polymorphism in the type 2 deiodinase gene (DIO2), wherein the subpopulation of patients with this genetic alteration had improved well-being and preference for combination therapy (7). This has led investigators to consider whether this polymorphism could confer a defect in the D2 pathway, but normal Thr92AlaD2 enzyme kinetics have been demonstrated (73). Only recently has the Thr92AlaD2 protein been found to have a longer half-life, ectopically localize in the Golgi apparatus, and significantly alter the genetic fingerprint in cultured cells and in the temporal pole of the human brain without evidence of reduced thyroid hormone signaling (74). The significance of these studies transcends the thyroid field—this polymorphism has now been associated with a constellation of diseases, including mental retardation, bipolar disorder, and low IQ (75). If hypothyroid carriers of Thr92AlaD2 benefit from alternate therapeutic strategies in replicate studies, then personalized medicine—based on genotype— may have a role.
Probiotics can help heal the gut and aid in nutrient absorption while reducing inflammation. Other benefits of a high-quality probiotic include helping to maintain a stronger immune system, increasing energy from production of vitamin B12, reducing bacterial or viral growth in the gut such as candida, improving skin health, and helping with appetite control and weight loss.
A clinical trial investigating symptoms found that patients receiving l-thyroxine monotherapy, even with a normal TSH, displayed substantial impairment in psychological well-being compared with controls of similar age and sex (3). Because some hypothesized that this phenomenon came about only after adoption of l-thyroxine monotherapy, a study assessed combination therapy with l-thyroxine and l-triiodothyronine. Remarkably, the latter study showed that psychological measures improve in patients receiving combination therapy until serum TSH level is normal (6). In another study comparing l-thyroxine monotherapy versus desiccated thyroid, in which both groups had a normal TSH, many patients preferred desiccated thyroid and lost weight (60). Unfortunately, the solution to this complex problem is not as simple as reverting to combination therapy; the more than a dozen clinical trials on the subject have not shown benefit of superiority and preference for combination therapy, as previously reviewed (1, 3, 70).
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.
In effect, there is no single, specific diet or vitamin/mineral supplement that has been proven to eliminate thyroid disease, according to the National Center for Complementary and Alternative Medicine. If you would like more guidance on the right diet to meet your individual needs, you can consider working with a registered dietitian who has a specialty in thyroid health, or an integrative medicine physician.
Goitrogen Foods – Eating large amounts of raw Brassica vegetables like broccoli, cauliflower, cabbage, kale, soy and Brussels sprouts might impact thyroid function because these contain goitrogens, molecules that impair thyroid perioxidase. When consuming these cruciferous vegetables, it’s best to steam them for 30 minutes before consuming to reduce the goitrogenic effect and keep portions moderate in size. These pose more of a risk for people with iodine deficiencies.
*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).
“We summarized that adequate iodine nutrition of 150 mcg a day is essential for normal thyroid function but that an excessive intake—be it from a variety of sources (eg, fortified salt, supplements, seaweed, seafood)—can have the reverse effect: too much iodine can cause hypothyroidism and hyperthyroidism and too little iodine low may lead to hypothyroidism,” Dr. Leung says.
Kale reigns supreme in the land of leafy green vegetables that we often eat raw, but beware if you have an iodine deficiency. “Kale gets a big baddy,” Blum says. “Eat it cooked.” When raw, this dark green leaf steals the iodine from the thyroid gland. If you must, it’s ok to nosh on the green veggie in your salad, but stop at two servings a day. No need to get extra credit on the superfood.
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.
