When I look up Graves disease in my book "Prescription for Nutritional Healing" it states it is Hyperthyroidism which is when the thyroid gland produces too much thyroid hormone, resulting in an overactive metabolic state. One of the sympthoms is increased perspiration. It recommends eating foods like broccoli, Brussels sprouts, cabbage, cauliflower, kale, mustard greens, peaches, pears rutabagas, soybeans, spinach and turnips which help to suppress thyroid hormone production.
