Hyperthyroidism is a condition in which too much thyroid hormone is produced. The metabolism speeds up and causes chemical reactions in the body to speed up. To keep hyperthyroidism from getting worse, certain foods should be avoided.
Allergies to certain foods such as wheat, soy, corn and dairy products can make hyperthyroidism worse. Other allergen-causing foods products include preservatives and chemical additives.
Foods that interfere with thyroid function should be avoided. These include spinach, broccoli, turnip and mustard greens, cabbage, cauliflower and peanuts.
Hyperthyroidism can be made worse by consuming certain refined foods. These refined foods to avoid include sugar, pasta and white bread.
Iodine can block thyroid hormone production so avoid consuming things that contain large amounts of iodine. This includes shellfish and cough medicine.
Hyperthyroidism can be made worse by consuming too much alcohol, tobacco or caffeine. Avoid these products and talk to a doctor before consuming any caffeine.
