Thought to be one of the world’s earliest vegetables under cultivation, yams may be undergoing an identity crisis due to frequent comparison with sweet potatoes. Though yams don’t come close to the vitamin A content and carotenoid presence, this world-traveling tuber has a unique set of phytonutrients.
Besides strong antioxidants, including the enzyme superoxide dismutase, yams contain vitamin C, fiber, potassium, manganese, B vitamins, and a long line of other minerals like riboflavin, potassium, iron, and manganese.
Yams, which may have a role in stabilizing hormonal patterns and lowering risk of osteoporosis, shouldn’t be refrigerated before they’re cooked. Recipes can swing to the sweet or savory side, depending on your desire.
