Parsnips are an excellent source of vitamin C, folic acid, pantothenic acid, copper, manganese, and fiber. They also provide vitamin E; the B vitamins niacin, thiamine, riboflavin, and B6; and the minerals magnesium and potassium.
Parsnips are lower in calories and provide only about half as much protein and vitamin C as potatoes, but they contain more fiber and folic acid. Although closely related to carrots, they lack beta-carotene and, consequently, the orange color. Parsnips provide more potassium than carrots.Nutritional Facts
