Sweet Potatoes
Sweet potatoes, on the other hand, belong to the Convolvulaceae family and are native to the Americas. They are sweeter and softer than yams, with a smooth, thin skin that’s easy to peel. Sweet potatoes have a orange, yellow, or white flesh and are often smaller than yams.
Nutritional Comparison
