Sweet potatoes are fat-free, high in fiber and full of the vitamins that research suggests reduce your risk of life-shortening diseases. To stay healthy, we must eat more fruits and vegetables, and sweet potatoes are a great source of beta carotene(胡萝卜素)and other carotenoids(which the body turns into vitamin A). According to a study of the diets of almost 90,000 nurses, eating about one cup a day of fruits and vegetables rich in carotenoids can cut your risk of stroke in half and reduce your risk of heart disease by 22 percent. Other research suggests beta carotene protects against breast, lung and stomach cancers.
Beta carotene is the most famous member of the carotenoids family. In fact, a medium-sized sweet potato contains nearly 12mg of beta carotene(anti-aging experts usually suggest 6 to 11 mg per day). Sweet potatoes are also a low-fat source of vitamin E. Research has linked high E diets with a lower risk of heart disease. This vitamin pill in an orange jacket also packs a vitamin C punchit which has more C than apricots (a kind of fruit). Research suggests that vitamin C protects against ailments (小疾) ranging from cataracts(an eye disease) to cancer. In addition, a UCLA (University of California Los Angeles) study linked high vitamin C diets with a longer life. Recent studies have showed that antioxidant Vitamins C, E and beta carotene fight a fierce battle against free radicals (自由基），which cause cell (细胞)damage and lead to various illness. Therefore, to keep fit, eat more sweet potatoes.
