Nutritional value of sweet potato
Sweet potato contains dietary fiber, carotenoids, vitamin A, vitamin B, vitamin C, vitamin E, as well as potassium, iron, copper, selenium, calcium and more than 10 kinds of trace elements. Nutritionists call it the most nutritionally balanced health food with the highest nutritional value.
Sweet potatoes contain particularly high levels of beta-carotene, vitamin E and vitamin C. In particular, sweet potatoes are rich in lysine, which rice and flour lack. Mixing sweet potatoes with rice and flour provides a more complete protein supplement. In terms of overall nutrition, sweet potatoes are arguably the best of the grains and vegetables. People in Europe and the United States call it the “second bread”. Scientists in the former Soviet Union called it the “space food” of the future, while the French called it a worthy “health food for the elderly”.
Each 100 grams of fresh sweet potato contains only 0.2 grams of fat and produces 99 calories, about one-third of rice. It is a good low-fat, low-calorie food. Sweet potatoes contain an estrogen-like substance, which has a role in protecting human skin and slowing down aging.
The most cancer-fighting nutrients in the diet are beta-carotene (a precursor to vitamin A), vitamin C and folate, all of which are rich in sweet potatoes. One small sweet potato (about twice as much) provides twice the body's daily requirement of vitamin A, one-third of the daily requirement of vitamin C, and about 50 micrograms of folic acid. The dietary fiber content is higher than a bowl of oatmeal porridge.
