The edible tuber is highly nutritious and, unlike potatoes, contains no starch, but rather carbohydrate in a form that is metabolized into natural sugar. Today they are sold in produce markets stores and, when boiled or roasted like potatoes, are delicious. Raw, they have a sweet, nut-like taste. This plant is high in iron and ideal for diabetics, because when ingested it does not increase glucose levels.
