Why purple sweet potatoes are better than other sweet potatoes!!
Vitamins
Sweet potatoes are loaded with vitamin A, packing almost 700% of the recommended daily value in one medium potato; all the others have none. Purple sweet potatoes also have about twice the vitamin C of other swee potatoes.
They all are great sources of potassium, with red potatoes leading the pack. Purple and red potatoes are unique in the fact that they are packed with antioxidants. The purple potato is full of the antioxidant anthocyanin, like most blue/purple foods.
