Best Superfoods to Eat
The moist-fleshed, orange-hued sweet potato has the highest nutritional value compared to a host of other vegetables.
Its vibrant color is a clue to its high concentration of Vitamin A in the form of beta-carotene. One sweet potato contains five times the recommended daily allowance of Vitamin A, a powerful antioxidant that protects against free radicals and helps guard against smoking-related diseases like emphysema and lung cancer. Sweet potatoes are also a good source of Vitamin C and the trace mineral manganese.
