In one study, the proteins had about one-third the antioxidant activity of glutathione - one of the body's most impressive internally produced antioxidants. More research is needed.
Recently the sweet potato has been classified as an "anti-diabetic" food. They have been given this label because of some animal studies in which the potato helped in stabilizing blood sugar levels and lowered insulin resistance. Some of these blood sugar regulatory properties may come from the fact that sweet potatoes are concentrated in carotenoids. More research is needed in this area.
Antioxidant-rich, anti-inflammatory food
As a wonderful source vitamin A -in the form of beta-carotene- and a good source of vitamin C, they have healing properties as an antioxidant food. Both beta-carotene and vitamin C are very powerful antioxidants. Sweet potatoes are also rich in vitamin B6, which has been associated with decreasing the risk of heart attack and stroke.

If you smoke or are frequently exposed to secondhand smoke, then making vitamin A-rich foods, such as sweet potatoes, part of your healthy way of eating, may save your life; as research conducted at Kansas State University suggests. A common carcinogen in cigarette smoke induces vitamin A deficiency, and a diet rich in vitamin A can help counter this effect, greatly reducing your chances of getting emphysema.
