The Health Benefits of Celeriac

Celeriac, also known as celery root, is an unusual and nutritious vegetable with a wide variety of uses. It is from the same family as celery but is a very different plant.

Celeriac that has been washed and peeled can be eaten raw or cooked using different methods.

This article explores the nutritional content of celeriac, its possible health benefits, and how to use it in recipes.

What is celeriac?

celeriac

Celeriac contains many nutrients and is similar in taste to celery and parsley.

Celeriac has green leaves and stalks that grow above ground, and a root covered in rough, brown skin that grows underground.

The edible part of the celeriac plant is the root. Inside it is pale in color, similar to that of a potato or turnip. Its flavor is similar to celery and parsley.

Celeriac contains multiple nutrients that may offer health benefits, as part of a healthy diet, including:

  • vitamin C
  • vitamin K
  • vitamin B-6
  • potassium
  • phosphorus
  • fiber

Celeriac originated in Mediterranean and north European countries. Ancient Egyptians, Greeks, and Italians used it for medicinal and religious purposes. Scientists first wrote about it as food in the 1600s, and it remains popular throughout Europe.

Celeriac vs. celery

While celery is grown for its edible leaves and stalks, celeriac is grown for its roots. Celeriac is sometimes called celery root, but it is not the root of celery stalks.

Other names for celeriac are knob celery and turnip-rooted celery, and it is the same family as carrots and related to celery, parsley, and parsnips.

Health benefits of celeriac

Bone health

Rich in vitamin C, celeriac could help reduce the risk of high blood pressure.

Vitamin K intake may impact bone health. Celeriac is high in vitamin K with a 1 cup of raw celeriac containing 64 micrograms (mcg).

Researchers reviewed studies that looked at the relationship between vitamin K and bone fractures. They found that people with higher dietary vitamin K intake had a lower risk of fractures.

Specifically, they noted that risk of fracture reduced by 22 percent in people with the highest vitamin K intake compared with those with the lowest.

Diabetes

Diabetes affects millions of people around the world. A healthful diet may lower the risk for type 2 diabetes.

In one large study in Europe, scientists examined the association between fruit and vegetable intake, including root vegetables, and risk for type 2 diabetes.

They found that people who ate the most root vegetables had a 13 percent lower risk of developing type 2 diabetes than those who consumed the least amounts.

Eating the root of the celeriac plant is one way to increase intake of root vegetables.

Heart health

In one study, scientists looked at the association between plasma ascorbic acid, a marker of vitamin C in the blood, and risk for high blood pressure. They found that people with higher blood levels of ascorbic acid had a lower risk of developing high blood pressure.

Consuming foods that are high in vitamin C, such as celeriac, could help lower the risk for high blood pressure by improving ascorbic acid levels.

Nutritional information

According to the United States Department of Agriculture (USDA) National Nutrient Database, 1 cup of raw celeriac provides:

  • 66 kilocalories (kcal)
  • 2.34 grams (g) of protein
  • 0.47 g of fat
  • 14.35 g of carbohydrate
  • 2.8 g of fiber

Celeriac is a concentrated source of many nutrients. A 1-cup serving of raw celeriac provides the following daily value (DV) percentages:

  • 11 percent of fiber
  • 13 percent of potassium
  • 13 percent of vitamin B-6
  • 18 percent of phosphorus.

Celeriac is high in vitamins C and K, providing 21 and 80 percent of the DV for those nutrients, respectively.

Recipes

celeriac in salad

Celeriac can be used uncooked, sliced, or grated and added to salads.

Celeriac is a versatile vegetable that can be eaten raw or cooked.

Raw celeriac is commonly used in salads. It may be best known for its use in a French dish called celerie remoulade.

Cooked celeriac can be prepared by baking, boiling, frying, or steaming. It can also be mashed and served as a side dish, or chopped and added to soups.

See below for a few celeriac recipes:

Substitutes

If celeriac is not available, celery and parsley root can be switched for a similar flavor in soups. For mashing or roasting, parsnips or potatoes could be used in place of celeriac.

Often, celeriac and potatoes are prepared using similar methods, or they can be substituted for one another in recipes. Celeriac can also be used as an alternative to potatoes for people trying to lower their calorie or carbohydrate intake.

According to the USDA National Nutrient Database, one cup of boiled celeriac pieces provides 42 kcal and 9.14 g of carbohydrate. The same amount of boiled potatoes provides 134 kcal and 31.22 g of carbohydrate.
