Question: are baked sweet potatoes high in fiber?
Answer: Fiber. Cooked sweet potatoes are relatively high in fiber, with a medium-sized sweet potato containing 3.8 grams. The fibers are both soluble (15–23%) in the form of pectin, and insoluble (77–85%) in the form of cellulose, hemicellulose, and lignin (12, 13 , 14).
