Regular potatoes of any kind, except for the deep purple and blue fleshed varieties, not good food for diabetics. Too much starch for the fiber and nutrients consumed. Regular potatoes spike blood sugar.
Sweet potatoes, high in nutritional value, and fiber. Low glycemic load.
Good for everyone.
Fired regular potatoes are especially bad as they combine a high starch food, and excessive oil. Also, it has recently been determined that potatoes fried in hot oil are mildly carcinogenic. But man, do they ever taste great.
Sweet potato skins are edible.
