Fact 12: Impact of Diet on Thyroid Health
As we’ve discussed various aspects of thyroid disorders and thyroid cancer, it’s essential not to overlook the role of diet in thyroid health. The food we consume can significantly impact the function of this tiny yet mighty gland.
Certain nutrients are particularly vital for thyroid health. Iodine, a mineral found in various foods, is used by the thyroid to produce thyroid hormones. Consuming too little can lead to hypothyroidism, while too much can trigger hyperthyroidism, or overactive thyroid. Foods rich in iodine include seaweed, dairy products, and iodized salt.
Selenium and zinc are other key nutrients for thyroid function. Selenium helps protect the thyroid gland from oxidative damage, while zinc is required for the synthesis of thyroid hormones. Good sources of these minerals include Brazil nuts (selenium) and oysters (zinc).
However, it’s not just about adding these foods to your diet. Certain foods and substances can interfere with thyroid function or the absorption of thyroid medication. For instance, highly processed foods and certain types of vegetables like broccoli and cauliflower, known as goitrogens, may interfere with thyroid hormone production if consumed in large amounts.
