Rutabaga and other cyanoglucoside-containing foods (including cassava, maize (corn), bamboo shoots, sweet potatoes, and lima beans) release cyanide, which is subsequently detoxified into thiocyanate. Thiocyanate inhibits thyroid iodide transport and, at high doses, competes with iodide in the organification process within thyroid tissue. Goitres may develop when there is a dietary imbalance of thiocyanate-containing food in excess of iodine consumption, and it is possible for these compounds to contribute to hypothyroidism. Yet, there have been no reports of ill effects in humans from the consumption of glucosinolates from normal amounts of "Brassica" vegetables. Glucosinolate content in "Brassica" vegetables is around one percent of dry matter. These compounds also cause the bitter taste of rutabaga.
