Sweet potatoes contain beta carotene, the pigment responsible for their orange hue. This chemical compound protects people’s eyes from ultraviolet radiation, preventing blindness and improving vision at night. Another virtue of the sweet potato is its fiber, which flushes out fats and keeps cholesterol from building up in arteries.
This food is good for skin and mucous membranes, and is an important factor in anti-aging, preventing wrinkles and stimulating hair and nail growth. Interestingly, a sweet potato boasts more vitamin A than a carrot.
