Just like all vegetables, turnips are low in calories and saturated fat. They're also an excellent source of several vitamins and minerals: Calcium: When you think of calcium, you might believe dairy is one of the only ways to get calcium. Turnips have a high amount of calcium, which helps to build strong bones and stay ahead of osteoporosis. Dietary fiber: Turnips have a substantial amount of dietary fiber, which can help with digestion, including diverticulitis. Folate: This nutrient is critical for pregnant women as it can reduce the risk of congenital disabilities found in the spine and brain. It also helps to produce red blood cells in the body. Potassium: Turnips provide potassium, which can help lower blood pressure by removing sodium from the body and helping the arteries dilate. Vitamin C: The turnip's greens are rich in this vitamin, which protects cells and keeps them healthy.
