Certain nutrients and compounds can potentially interfere with thyroid health, and while they don’t need to be completely avoided, managing their intake may be helpful for individuals with hypothyroidism.
Here are some foods and factors to consider:
Goitrogens:
Goitrogens are compounds that can affect thyroid function when consumed in large amounts. However, regular amounts of goitrogenic vegetables like broccoli and bok choy are generally beneficial and don’t significantly impact thyroid function. Cooking these vegetables also reduces the goitrogenic compounds. Common goitrogenic foods include collards, Brussels sprouts, Russian kale, broccoli, broccoli rabe, cauliflower, and cabbage.
Soy:
Some evidence suggests that soy consumption may interfere with thyroid hormone production. While more research is needed to fully understand the effects of soy on thyroid function, it’s worth considering for individuals with hypothyroidism. Soy-containing foods include soy milk, soy sauce, edamame, tofu, and miso.
Gluten:
People with Hashimoto’s disease, a common cause of hypothyroidism, are more likely to have celiac disease, as both are autoimmune disorders. Removing gluten from the diet has been shown to improve thyroid function in individuals with Hashimoto’s and without celiac disease. Gluten is found in wheat and other grains like barley, oats, and rye. If you have autoimmune-related hypothyroidism, trying a gluten-free diet may be worth considering.
Processed Foods:
Reducing the intake of ultra-processed foods and added sugars can improve symptoms, help manage weight, and enhance overall well-being. Examples of ultra-processed foods and drinks high in added sugar include fast food, hot dogs, donuts, cakes, cookies, and soda.
Other dietary considerations for individuals with hypothyroidism include taking thyroid medication on an empty stomach, avoiding consuming iron or calcium-rich foods within four hours of taking medication, and being cautious about medications, supplements, and foods that can interfere with the absorption of thyroid medication (e.g., antacids, milk, calcium supplements, iron supplements, high-fiber foods, and foods high in iodine).
It’s important to note that individual responses may vary, and consulting with a healthcare professional or registered dietitian is advisable to determine the best dietary approach for managing hypothyroidism.
