Hypothyroidism-friendly foods include sardines, wild salmon, tuna, trout and other fish rich in omega-3 fatty acids; macadamia nuts, hazelnuts and Brazil nuts; rice, bread, pasta, cereal and other whole-grain foods; and fresh fruits and vegetables, reports Everyday Health. Iodine-rich seaweed, vitamin D-rich fortified milk and high-protein beans also contribute to thyroid health.
Fish and other foods rich in omega-3 fatty acids are good for patients with hypothyroidism, because they help boost the immune system, reduce inflammation and decrease the risk of heart disease, explains Everyday Health. Found in fish and nuts, selenium reduces inflammation and is necessary for the thyroid. Nuts can be added to salads and stir-fried items. One to two pieces of Brazil nuts or small portions of other nuts provide adequate daily nutrients.
Whole grains improve bowel movements and relieve constipation, which commonly occurs in patients with hypothyroidism, notes Everyday Health. However, patients who take synthetic thyroid hormones should avoid eating whole grains.
Weight gain results from hypothyroidism, and patients can maintain healthy weights by consuming foods with low calories and high density, such as fresh produce, states Everyday Health. Doctors advise eating a maximum of 5 ounces of cruciferous vegetables daily, because they absorb iodine. Iodine is important for the proper functioning of the thyroid gland, but patients must avoid consuming too much iodine to avoid aggravating thyroid disease.
