The thyroid is a gland is located in the lower part of the neck. Its primary functions are to secrete hormones that deliver energy to cells throughout the body and change iodine from food into thyroid hormones. This is essential in regulating metabolism. Thyroid conditions occur for many reasons, including iodine deficiencies, stress, genetics and, last but not least, diet. Certain foods affect the thyroid and by eating some foods and avoiding others, you can improve the function of your thyroid.
Iodine Foods
Iodine helps the thyroid produce hormones and specific foods are rich in iodine. Kelp, which is a form of seaweed, probably has the highest concentration of iodine. The best way to ingest kelp is through two foods: Kombu, which is a base for broths, and Wakame, used in soups and stir-fries. Shellfish is also high in iodine as is asparagus and beef liver.
Tyrosine Foods
Tyrosine is an amino acid that is important in the functioning of thyroid hormones and neurotransmitters. People with thyroid conditions such as hypothyroidism tend to be deficient in tyrosine. Incorporating foods rich in tyrosine may be helpful. Some foods that should be included would be turkey and chicken breast, fish, dairy products, wheat and oats, almonds, lima beans, lentils, bananas, avocado, pumpkin seeds and sesame seeds.
Zinc and Copper Foods
Making thyroid hormones is very important, and zinc can help facilitate this process. There are foods that are rich in zinc. Free-range beef and chicken are a good source of zinc. Oysters and shellfish also contain high levels of zinc. Oatmeal, wheat germ, wheat bran, seeds and nuts are just a few more foods that can add zinc to your diet. Copper-rich foods include eggs, nuts, raisins, legumes and yeast.
Selenium Foods
Selenium is a trace mineral that can help thyroid function and produce specific hormones that affect the thyroid. Foods that contain selenium are onions, black-strap molasses, lean meats, chicken, seafood, whole unrefined grains, Brazil nuts, brewer's yeast, macaroni noodles, broccoli, dairy products and garlic.
Foods to Avoid
Avoid saturated fats, refined foods, soy products, sugars and white flour. Try to avoid cruciferous vegetables as they are thyroid inhibitors and contain enzymes that interfere with the formation of thyroid hormones. Cruciferous vegetables include arugula, Brussels sprouts, bok-choy, broccoli, broccoflower, mustard and collard greens, cabbage, turnips, cauliflower, chard, radishes and watercress.
