Sweet potatoes have been cultivated for more than 5,000 years. Originally from South America, sweet potatoes are now grown all over the world. Rich in fiber, protein, vitamins A and C, and the minerals iron and calcium, sweet potatoes are also packed with carotene and anthocyanins—the powerful antioxidants.
The Center for Science in the Public Interest ranked the baked sweet potato the most nutritious of all vegetables with a score of 184. That’s 100 points higher than the runner-up, the baked white potato.
