Health Benefits of Turnips:
One cup of mashed turnips contains about 27 mg of vitamin C, an antioxidant. Most adults should consume between 75 and 90 mg of vitamin C daily to support tissue repair and immunity. Turnips also provide most of the B vitamins, including riboflavin, thiamin, niacin, folate and pantothenic acid. One cup also has 0.2 mg of the 1.3 mg of vitamin B6 you need daily. The B vitamins help with fat, carbohydrate and protein metabolism; nervous system function; and healthy skin, hair, eyes and liver.
Turnips have 76 mg of calcium per mashed cup -- about 8 percent of the recommended daily value. You also get 407 mg of potassium, essential to healthy blood pressure and fluid balance, per cup. You need about 2,000 mg of potassium daily. Turnips also contain small amounts of iron, magnesium, phosphorus, sodium, zinc, manganese and selenium.
