Sweet potatoes are a nutritional powerhouse. An excellent source of beta-carotene, a powerful antioxidant, they’re also a good source of vitamin C, dietary fiber, and potassium. Best of all, they taste like a dessert! The “sweet” in these potatoes comes from an enzyme that converts most of the tuber's starches to sugars as it matures. This sweetness intensifies during storage and as the potato is cooked. This is one holiday favorite worth adding to your meals year round.
