Turnips Nutrition facts

Turnips are popular, nutritious root vegetables. They are round, tuberous roots grown in many parts of Europe, and Asia as one of the cool-season vegetables.

Botanically, they belong to the Brassicaceae family, a broad group of greens and vegetables that also includes cabbage, kale, brussel sprouts, etc.

Scientific name: Brassica rapa (Rapifera Group).


Tiny, young turnips or “baby turnips” are harvested quite early at their growing stage. Baby turnips feature a delicate, sweeter taste and can be eaten raw in salads. However, as they advance in size and maturity, their flavor becomes more pronounced, loses texture, and becomes hard and woody.

Rutabaga is another root vegetable that is closely related to turnips. Rutabagas are larger, rounder, and sweeter in flavor than turnips. Inside, they feature yellow flesh in contrast to the pearly-white flesh of turnips. Both these roots have been cultivated as a staple food since the ancient Greek and Roman periods.

Although this bulbous root is widely recognized as a popular tuber vegetable, its fresh green tops indeed are more nutritious, several times richer in vitamins, minerals, and antioxidants.

Selection and storage

Fresh turnips can be available year-round. However, fresher and sweeter roots flood the stores in abundance from October through March. Fully grown tubers measure about two to three inches in diameter and weigh between 60 to 250 g.

Fresh tubers are usually sold either in a bunch with top greens or topped. In the markets, look for medium-sized, firm, round tubers that impart delicate sweet flavor.

Avoid larger as well as overmatured roots as they are hard, woody, and fibrous, and therefore, unappetizing.

Once at home, separate the top greens from their root as the greens rob nutrients off the tubers.

The roots can be stored for a few weeks in cold storage (32°-35° F) and high relative humidity (95 percent or above). Use top greens as early as possible since they lose nutrients rather quickly.

Preparation and serving methods

Both root and its top greens can be used in cooking. Wash roots in cold running water to remove sand, soil, and any fungicide residues from the surface. Trim the top and bottom ends. Peeling may not be necessary if roots are young; however, large turnips feature tough skin and require peeling.

Here are some serving tips:

  • Young turnips are one of the favored items in raw salads for their sweet taste, complementing with cabbage, parsnips, carrots, and beets.

  • Its cubes can mix well with other vegetables like kohlrabi, potato, carrots in the preparation of a variety of stews.

  • Diced turnips can be added to poultry, lamb, and pork.

  • Add raw baby turnip slices with olives and cherry tomatoes to prepare a delicious appetizer.

  • Turnip cubes can be pickled in a way similar to other vegetables like radish, chili-peppers, carrot in many parts of Northern India, Iran, and Pakistan.

  • Top greens are used with other greens and vegetables in soups, curries, and stews.

Safety profile

Turnips and top greens are very safe to eat, including in pregnant women.

However, the root and its top greens contain a small amount of oxalic acid (0.21 g per 100 g), a naturally occurring substance found in some vegetables belonging to the Brassica family, which may crystallize as oxalate stones in the kidneys and urinary tract in some people. It is, therefore, those with known oxalate urinary tract stones may want to avoid them in the food.

To minimize the stone formation risk, people are advised to drink sufficient water to maintain normal urine output. (Medical disclaimer).
