Sweet potato (Ipomoea batatas) is a plant ingredient used in pet foods as a source of carbohydrate, fiber, and beta-carotene. Compared with white potato, it offers richer provitamin A content and a stronger antioxidant profile. In grain-free formulations, it is generally viewed as a more nutrient-dense carbohydrate option than plain starch fillers.
