Cabbage might not be the most popular vegetable in the world, but it has a number of health benefits that make it a valuable addition to your diet. Cabbage is considered a goitrogen, which is a substance that can help to lower the thyroid hormone levels in your body. Graves’ Disease is an incurable disease in which your thyroid levels are excessively high, resulting in a wide range of dangerous and sometimes debilitating symptoms. By adding cabbage to your stews or salads, you can significantly reduce the issues associated with this disease by keeping your thyroid levels in check.
