Sweet Potatoes - A Dietary Gold Mine
Sweet potatoes are plentiful, inexpensive, versatile and one of our most nutritious foods. Best of all, they taste good. Nutrition and disease-prevention specialists have touted their virtues for years.
Sweet potatoes are high in antioxidant vitamins, which help our bodies fight aging, heart disease and cancer. An average sweet potato has four times the recommended dietary allowance of beta carotene, or vitamin A. They are also a good source of hard-to-get antioxidant vitamin E and they are fat free. Many other foods high in vitamin E, such as nuts and avocados, are high in fat. Two-thirds cup of mashed sweet potatoes supply 100-percent of the RDA for vitamin E.
Sweet potatoes are also high in vitamin C, providing half the day's RDA in one medium potato. They also contain vitamin B6, potassium and iron.
One medium baked sweet potato, including the skin, contains an impressive 3.4 grams of fiber, according to the USDA Nutrient Database. Eat the skin whenever you can because it provides much of the fiber.
