The turnip also provides you with small amounts of other nutrients your body needs, making it a valuable supplement to your diet. A cup of cooked turnip contains small amounts of calcium, magnesium, iron, folate, potassium, zinc, phosphorus, thiamin and riboflavin. It also gives you about 4 grams of dietary fiber, approximately 16 percent of the amount you need each day. Raw turnip is slightly higher in fiber, providing you with about 5 grams per serving.
