Dragon fruits have a surprising number of phytonutrients. Rich in antioxidants, they contain vitamin C (equivalent to 10 percent of the daily value), polyunsaturated (good) fatty acids, and several B vitamins for carbohydrate metabolism, as well as carotene and protein. Calcium is present for strong bones and teeth, iron and phosphorus for healthy blood and tissue formation. The benefits are realized in a number of ways, from a strengthened immune system and faster healing of bruises and wounds to fewer respiratory problems.

Dragon fruits have zero complex carbohydrates, so foods can be more easily broken down in the body, helped by vitamin B1 (thiamin) and other B vitamins.
