Celeriac is an unusual and nutritious vegetable with a wide variety of uses. It may offer several health benefits, such as improving bone and heart health.
Celeriac has green leaves and stalks that grow above ground and roots with a rough, brown skin that grow underground. While farmers grow celery for its edible leaves and stalks, they grow celeriac for its roots.
Some people refer to celeriac as celery root, but it is not the root of a celery stalk.
Other names for celeriac are knob celery and turnip-rooted celery. It belongs to the same plant family as carrots and is related to celery, parsley, and parsnips.
The edible part of the celeriac plant is the root. Inside, the root is pale and resembles a potato or turnip. Its flavor is similar to that of celery and parsley. A person can eat washed and peeled celeriac raw or prepare it using different cooking methods.
In this article, we explain the possible health benefits of celeriac, as well as its nutritional content and how to use it in recipes.
Celeriac potentially boosts bone and heart health, and it may reduce the risk of diabetes.

They found that the people who ate the most root vegetables had a risk of diabetes that was 13% lower than that of those who consumed the least.
The study authors found that eating root vegetables did not affect the likelihood of developing metabolic syndrome.
More research is necessary to confirm the protective benefits of root vegetables, such as celeriac, against diabetes.
In one 2015 study involving 2,884 adults, researchers examined the association between plasma ascorbic acid, a marker of vitamin C in the blood, and a person's risk of high blood pressure.
They found that participants with higher blood levels of ascorbic acid had a
Consuming foods that are high in vitamin C, such as celeriac, could help a person reduce their risk of high blood pressure by improving their ascorbic acid levels. High blood pressure is a leading cause of stroke and cardiovascular disease.

Celeriac is a concentrated source of many nutrients, including:

Raw celeriac is common in salads. It may be best known for its use in a French dish called celeri remoulade.
It is possible to bake, boil, fry, or steam celeriac. People can also mash celeriac and serve it as a side dish or chop it for inclusion in soups.
Try a few celeriac recipes below:

If celeriac is not available, people can use celery and parsley root to achieve a similar flavor in soups. For mashing or roasting, parsnips or potatoes would make a suitable alternative.
People often prepare celeriac and potatoes using similar methods, and it is possible to substitute one for the other in recipes. Celeriac can also serve as an alternative to potatoes for people who are trying to reduce their calorie or carbohydrate intake.
According to the USDA, one cup of boiled celeriac pieces contains 42 calories and 9.14 g of carbohydrate. The same amount of boiled potatoes provides 134 calories and 31.2 g of carbohydrate.
