A Detailed Look at Celeriac's Nutritional Profile
Often called celery root, celeriac is a low-calorie, nutrient-dense root vegetable that offers a distinct, earthy flavor with hints of celery and parsley. Its complex carbohydrate structure, rich in dietary fiber and low in sugar, makes it a valuable alternative to more starchy vegetables like potatoes. A standard one-cup serving of raw celeriac provides a wealth of essential vitamins and minerals.
Key Vitamins and Minerals
Celeriac is particularly known for its high concentration of several key micronutrients:
- Vitamin K: A single cup of raw celeriac can provide more than 50% of the daily value for vitamin K, a crucial nutrient for blood clotting and promoting strong bone mineralization.
- Vitamin C: This powerful antioxidant supports immune function, aids in wound healing, and helps combat oxidative stress.
- Potassium: An essential mineral that plays a vital role in regulating blood pressure, supporting heart rhythm, and controlling muscle contractions.
- Phosphorus: Crucial for bone formation, energy production, and the regulation of gene transcription.
- Manganese: A cofactor for many enzymes involved in metabolism and antioxidant defense systems within the body.
- B Vitamins: Celeriac provides various B vitamins, including B6, which supports the immune and nervous systems.
Antioxidants and Anti-inflammatory Properties
Beyond its core vitamins and minerals, celeriac contains a variety of antioxidants and bioactive compounds. These include flavonoids like apigenin and kaempferol, which have been shown to have potent antioxidant and anti-inflammatory properties. These compounds help neutralize free radicals, reduce oxidative stress, and may mitigate chronic inflammation, which is linked to diseases such as heart disease and diabetes.
The Health Benefits of Incorporating Celeriac
Adding celeriac to your diet can lead to several notable health improvements:
- Supports Digestive Health: With nearly three grams of dietary fiber per cup, celeriac aids digestion by promoting regular bowel movements and nourishing beneficial gut bacteria. This prebiotic effect helps maintain a balanced gut microbiome, which is vital for overall health.
- Boosts Cardiovascular Health: The high potassium content in celeriac helps counterbalance sodium, supporting healthy blood pressure levels. Furthermore, its vitamin K content helps prevent the calcification of arteries, reducing the risk of heart disease.
- Aids Weight Management: Celeriac is a low-calorie and low-carb vegetable that provides bulk and fiber, which promotes a feeling of fullness and can help curb appetite. Its moderate protein content also helps slow the emptying of the stomach, further aiding satiety.
- Promotes Strong Bones: The synergistic effect of vitamin K, calcium, and phosphorus in celeriac contributes to strong and healthy bones. Vitamin K is essential for activating osteocalcin, a protein that supports proper bone mineralization.
- Regulates Blood Sugar: The significant fiber content in celeriac slows the absorption of sugar into the bloodstream, which helps prevent sharp spikes and crashes in blood sugar levels. This makes it a great option for those managing diabetes or seeking stable energy throughout the day.
Celeriac vs. Potatoes: A Nutritional Comparison
Celeriac is often used as a lower-carb, more nutrient-dense alternative to potatoes in many recipes. Here is a comparison of the nutritional content per 100 grams (approximate):
| Nutrient | Celeriac (Raw) | Potato (Boiled) |
|---|---|---|
| Calories | ~42 kcal | ~87 kcal |
| Carbohydrates | ~9.2 g | ~20.1 g |
| Fiber | ~1.8 g | ~2.1 g |
| Sugar | ~1.6 g | ~1.1 g |
| Vitamin K | 41 mcg | 1.9 mcg |
| Vitamin C | 8 mg | 12.3 mg |
| Potassium | 300 mg | 379 mg |
This table illustrates that while potatoes are a good source of potassium and vitamin C, celeriac is significantly lower in carbohydrates and calories, and provides a much greater amount of vitamin K. Its lower glycemic load makes it a preferred choice for individuals on low-carb or keto diets.
Culinary Uses and Preparation
Despite its unrefined exterior, celeriac is incredibly versatile in the kitchen. Its nutty, subtle flavor can be enjoyed both raw and cooked. For preparation, the knobby brown skin must be peeled away with a sharp knife to reveal the creamy white flesh inside.
- Raw: Grated celeriac is a classic ingredient in French céleri rémoulade and can be added to slaws and salads for a fresh, crunchy texture.
- Cooked: Celeriac can be roasted with other root vegetables, boiled and pureed into a creamy mash, or added to soups and stews. It can also be baked into crispy fries or sliced thin for gratins.
- Soups and Purees: When cooked, celeriac becomes soft and sweet, making it an excellent base for creamy, comforting soups. Its mild flavor pairs well with herbs like thyme and parsley.

Celeriac root is a highly nutritious and versatile vegetable that deserves a prominent place in any healthy diet. Its rich profile of vitamins, minerals, and antioxidants supports a wide range of bodily functions, from bolstering bone health and immune response to promoting digestive health and regulating blood sugar.
