About Purple sweet potato
Purple sweet potatoes are root vegetables belonging to the Ipomoea genus, prized for their vibrant purple hue, which comes from anthocyanins, a type of antioxidant.

Widely used in both sweet and savory cuisines, they are a staple in dishes like stews, desserts, and baked goods. Purple sweet potatoes are rich in complex carbohydrates, dietary fiber, and essential micronutrients, including vitamin A, vitamin C, potassium, and manganese, while being low in fat and cholesterol-free. They are a nutrient-dense food, offering a slightly sweet flavor and creamy texture when cooked.
