Celeriac, a distinctive root vegetable also known as celery root, offers an array of health benefits. This knobby, brown-skinned vegetable belongs to the same family as celery but is grown for its bulbous root rather than its stalks. Celeriac is rich in antioxidants, vitamins, and minerals that can support overall health and wellness.
The nutritional profile of celeriac includes significant amounts of vitamin K, vitamin C, and potassium. These nutrients contribute to bone strength, immune function, and heart health. Celeriac also contains fiber, which aids digestion and helps maintain stable blood sugar levels.
Incorporating celeriac into one’s diet may provide additional health advantages. Its anti-inflammatory properties, derived from antioxidants, can help protect cells from damage. Some research suggests celeriac might play a role in preventing type 2 diabetes, though more studies are needed to confirm this potential benefit.

Health Benefits of Celeriac
Celeriac offers numerous health advantages due to its rich nutrient profile and bioactive compounds. This versatile root vegetable supports multiple bodily functions and may help prevent certain diseases.
Cardiovascular Health
Celeriac contributes to heart health through its potassium content. Potassium helps regulate blood pressure by counteracting the effects of sodium. This can reduce strain on the cardiovascular system and lower the risk of heart disease and stroke.
The fiber in celeriac also plays a role in cardiovascular health. It helps reduce LDL cholesterol levels, which can decrease the risk of atherosclerosis. Fiber binds to cholesterol in the digestive tract, preventing its absorption into the bloodstream.
Celeriac contains antioxidants that protect blood vessels from oxidative stress. These compounds help maintain the flexibility and integrity of blood vessel walls, promoting better circulation.
Bone Strength and Structure
Vitamin K in celeriac is crucial for bone health. It activates osteocalcin, a protein that helps bind calcium to bones. This process strengthens bone structure and may reduce the risk of osteoporosis.
Celeriac also provides calcium, another essential mineral for bone health. While not as high in calcium as dairy products, it contributes to overall calcium intake.
The vegetable contains phosphorus, which works with calcium to build strong bones and teeth. A balanced ratio of calcium and phosphorus is important for optimal bone mineralization.
Digestive System Support
The high fiber content in celeriac promotes digestive health. Fiber adds bulk to stool, preventing constipation and promoting regular bowel movements. It also feeds beneficial gut bacteria, supporting a healthy microbiome.
Celeriac’s fiber content can help reduce the risk of digestive disorders such as diverticulitis and hemorrhoids. By promoting smooth digestion, it may also alleviate symptoms of irritable bowel syndrome.
The vegetable’s water content contributes to hydration, which is essential for proper digestion. Adequate hydration helps prevent constipation and supports the overall function of the digestive tract.
Blood Sugar Regulation
Celeriac’s low glycemic index makes it beneficial for blood sugar control. It releases glucose slowly into the bloodstream, preventing rapid spikes in blood sugar levels.
The fiber in celeriac slows down carbohydrate digestion and absorption. This can help improve insulin sensitivity and reduce the risk of type 2 diabetes.
For those with diabetes, incorporating celeriac into meals can aid in managing blood glucose levels. Its low carbohydrate content makes it a suitable vegetable choice for diabetic diets.
Diuretic Properties
Celeriac acts as a natural diuretic, increasing urine production and helping flush out toxins from the body. This property can be beneficial for kidney health and reducing fluid retention.
The diuretic effect of celeriac may help lower blood pressure by reducing the volume of fluid in the bloodstream. This can ease the workload on the heart and blood vessels.
By promoting urine production, celeriac can assist in preventing urinary tract infections. Regular urination helps flush out bacteria that might otherwise colonize the urinary tract.
Incorporating Celeriac in Your Diet
Celeriac offers versatility in the kitchen, lending itself to both raw and cooked preparations. This root vegetable can enhance various dishes with its unique flavor and texture while providing numerous health benefits.
Raw Celeriac Uses
Raw celeriac adds a crisp, refreshing element to salads and slaws. Grate it finely and mix with carrots, apples, and a light vinaigrette for a nutritious slaw. Thinly sliced celeriac makes an excellent addition to crudité platters, paired with hummus or other healthy dips.
For a simple side dish, julienne raw celeriac and toss with lemon juice, olive oil, and fresh herbs. This raw preparation preserves the vegetable’s high vitamin C content, supporting immune function and skin health.
Cooked Celeriac Dishes
Cooked celeriac shines in soups and stews, imparting a subtle celery-like flavor. Dice it and add to vegetable soups for extra nutrition and a creamy texture when blended. In stews, celeriac chunks absorb flavors while maintaining their shape.
Roasting brings out celeriac’s natural sweetness. Cut it into cubes, toss with olive oil and herbs, then roast until golden. This method enhances its earthy flavor and creates a delicious side dish rich in fiber and potassium.
Mashed celeriac serves as a lower-carb alternative to mashed potatoes. Boil cubed celeriac until tender, then mash with butter or olive oil and seasonings. This creamy puree pairs well with roasted meats or fish, offering a comforting yet nutritious option.
Selecting and Storing Celeriac
When selecting celeriac, look for firm, heavy bulbs with minimal blemishes or soft spots. The ideal size is about 4-5 inches in diameter, as larger ones can be woody and less flavorful.
Choose celeriac with fresh-looking leaves still attached, if possible. These indicate recent harvesting and better quality. Avoid any with discoloration, cracks, or signs of decay.
To store celeriac, trim off any leaves and place the bulb unwashed in a plastic bag. Keep it in the vegetable crisper of your refrigerator, where it can last up to 3-4 weeks.
For longer storage, wrap the celeriac in a damp paper towel before placing it in the plastic bag. This helps maintain moisture and freshness.
If you’ve cut into the celeriac, store unused portions in water with a squeeze of lemon juice to prevent browning. Use these within a few days for best quality.
At room temperature, celeriac will keep for about a week. Store it in a cool, dark place away from direct sunlight and heat sources.
Before using, wash the celeriac thoroughly and peel away the tough outer skin with a sharp knife. The white flesh underneath is ready for your culinary creations.
