Celery root, also known as celeriac, is a versatile and nutrient-rich root vegetable with a mild, earthy flavor and a firm texture. It belongs to the celery plant family but, unlike the familiar green stalks of celery, celery root has a round, knobby base with multiple protrusions and a leafy top, somewhat resembling a turnip or radish.
It can be eaten raw or cooked in soups, stews, and mashed dishes, making it a versatile ingredient in many recipes. When raw, it has a crunchy texture and a nutty, celery-like flavor that adds a delightful twist to salads. When cooked, its texture softens, and its flavor becomes more mellow, making it a great ingredient for soups, stews, and even mashed dishes. Celery root often finds itself compared to other root vegetables like turnips, parsnips, and carrots, but it truly stands out with its unique flavor and texture. Compared to turnips, celery root is generally sweeter and less bitter, offering a more pleasant taste for those who might find turnips too sharp. When placed alongside parsnips, celery root is less starchy and boasts a more delicate flavor, making it a versatile ingredient in various dishes.
While celery root provides essential vitamins, minerals, and fiber, its carbohydrate content and preparation methods can affect its overall nutritional value and compatibility with specific diets like the ketogenic diet.
Nutritional Profile of Celery Root
Celery is a nutrient-rich vegetable that provides a range of essential vitamins, minerals, and antioxidants. A one-cup serving of cooked celery root contains approximately 40-50 calories, 9-12 grams of carbohydrates, 2-3 grams of fiber, and 1-2 grams of protein, with minimal fat. Like other parts of the celery plant, celery root is low in calories and fat, making it a great option for those looking for a nutrient-dense, weight-friendly vegetable.
It is an excellent source of vitamin K, vitamin C, and B vitamins, which support immune function, bone health, and metabolism. Celery root provides essential minerals such as potassium, magnesium, and phosphorus, which contribute to heart health, muscle function, and electrolyte balance. Celery is also a good source of antioxidants, including flavonoids, carotenoids, and phenolic acids, which can help protect against oxidative stress and inflammation. Among the many celery benefits, its low calorie content and high dietary fiber can aid in weight management and overall health improvements. It is high in fiber, which supports digestion, promotes gut health, and helps regulate blood sugar levels. The potassium content in celery root helps regulate blood pressure and supports cardiovascular health, making it beneficial for those with high blood pressure. It is a good source of vitamin K, which plays a role in bone health and proper blood clotting.

Health Benefits of Celery Root
Due to its good supply of certain nutrients and antioxidants, celeriac may offer a variety of health benefits.
Antioxidant Properties
Celeriac is packed with antioxidants, which are anti-inflammatory - they work by fighting against harmful free radicals, thus protecting healthy cells from damage. In doing so, they may protect against many conditions, such as heart disease, cancer and Alzheimer’s. They may even offer anti-aging effects. Celeriac - especially raw - is also a good source of vitamin C, which acts as an antioxidant and may strengthen your immune system.
Heart Health
Celeriac is high in potassium and vitamin K, which are important for heart health. Potassium can help regulate blood pressure by neutralizing the negative effects of high salt intake in sensitive individuals. In fact, consuming higher levels of potassium has been linked to a lower risk of health issues, such as stroke. Vitamin K may reduce heart disease risk by preventing the buildup of calcium in your blood vessels. Such buildup may cause your blood vessels to become hard and narrow. Celeriac also contains vitamin C, which may improve blood vessel function and blood fats in certain people, such as those with diabetes or with low blood levels of vitamin C.

Digestive Health
Celeriac is classed as a high-fiber food. Getting enough dietary fiber can aid digestion, metabolism and bowel movements. In turn, this may protect against certain diseases, such as colon cancer. Evidence shows that sufficient fiber intake is essential for feeding your beneficial gut bacteria, which are extremely important for many different aspects of health such as protecting against diabetes and obesity.
Bone Health
Celeriac is a rich source of phosphorus and vitamin K, which are important for healthy bones. Vitamin K works by promoting calcium absorption and preventing bone loss. What’s more, in addition to calcium, your body needs adequate levels of phosphorus to strengthen bones. Observational studies found that a higher intake of phosphorus is associated with better bone health and a reduced risk of osteoporosis.
Potential Anticancer Properties
Celeriac is high in vitamin K, which may have anticancer properties. Several test-tube and animal studies found that vitamin K reduced the growth and spread of cancerous cells. However, more human research is needed to determine whether vitamin K can protect against cancer.
Celery Root and the Ketogenic Diet
When you follow the ketogenic approach to food, you'll need to base your diet around low-carb foods. Some foods are seemingly high in carbohydrates (per 100 grams), but you will only need to use a small amount when used in recipes. Celeriac, despite its commendable nutritional profile, is not a top pick for a strict keto diet due to its high net carb content. The primary reason for this cautious approach lies in the nutritional blueprint of celeriac. This underground veggie touts a specific macronutrient composition. Most relevant to our keto discussion is its carbohydrate content. Each 100g serving of celeriac contributes approximately 7.4g net carbs to your diet.
A hallmark of the ketogenic diet is its deliberate, stringent restriction on carbohydrate intake. As most of you would be aware, a keto regimen typically aims to limit net carb consumption to around 20g to 50g per day, depending on each person's unique metabolic constitution and objectives.

Is Celery Root Keto-Friendly?
Most people stick to eating vegetables on keto because it’s a low-carb diet. But celery root is not keto-friendly. Even though it’s a low-carb vegetable, you can knock yourself out of ketosis by eating too much of it. The key phrase here is “too much.”
The compatibility of celeriac with a ketogenic diet operates on a delicate balance of knowledge and control - a knowledge of its nutritional framework and control in its portion sizes. Because of celeriac's inherently higher carbohydrate allotment of 7.4g net carbs per 100g, it becomes apparent that even a small serving can claim a significant portion of the day's total carb budget. For instance, if one were to consume a 200g serving of celeriac, it would equal to around 14.8g net carbs-nearly 75% of the total allowance in a strict ketogenic diet.
Incorporating Celery Root into a Keto Diet
You don’t have to completely eliminate celery root because it isn’t keto. Celery root has been a staple in Eastern European kitchens for centuries. If it’s a part of your usual diet, you may not want to give it up. Feeling like you cannot eat the foods you enjoy will only become a barrier to your success on keto. The good news is, if you’re careful, you can still enjoy celery root from time to time.
For those who cherish celeriac's unique taste and texture and are willing to accommodate its carb content, careful portion control and mindful dietary balance become the keywords. The key is not merely in moderating the consumption of celeriac alone but also ensuring the rest of the dietary components for the day remain low in carbohydrates. One effective tool for ensuring this balance is carb tracking. Today, a variety of mobile apps and online tools are available designed specifically to help monitor your daily carb intake in correlation to the other macronutrients. By scrutinizing your food intake and becoming aware of the carbohydrate content of each ingredient, you can chart out an eating plan that incorporates a small amount of celeriac without disrupting your ketogenic journey.
Potential Challenges and Benefits of Eating Celeriac on Keto
Eating celeriac in moderate quantities while on a keto diet presents many potential benefits, but it can also set the stage for several challenges. The most immediate concern relates to maintaining a state of ketosis. Nudging over the line into excessive carb consumption risks disrupting ketosis and returning the body's reliance back to carbohydrates for fuel rather than fats. Yet, avoiding celeriac entirely might mean missing out on some of its health-promoting benefits. Additionally, this root vegetable possesses a suite of vitamins essential for optimum health. It's rich in vitamin C, a potent antioxidant that strengthens the immune system, increases the absorption of iron from the diet, and aids the formation of collagen for healthy skin and joints. Another consideration is the unique flavor profile that celeriac brings to the culinary table.
Strategies for Limiting Celery Root Consumption on Keto
Recognizing the carbohydrate value of celeriac, we quickly realize that imposing a limit on its consumption becomes critical on a ketogenic plan. Albeit nutritious, the relatively high net carb content of celeriac requires vigor in practicing portion control.
Here are some strategies for limiting celeriac in your keto meal plan without completely sacrificing its unique taste and nutritional merits:
- Mindful Portion Sizes: Instead of making celeriac the star of your dish, consider it as an accent ingredient. Considered portion sizes allow you to enjoy its unique flavor without substantially loading up on carbs.
- Cooking methods: The preparation method can go a long way in controlling portion sizes.
- Recipe Ideas: Consider a celeriac mash. This dish allows you to control the volume of celeriac you use and blend it seamlessly with other keto-friendly ingredients.
Keto-Friendly Alternatives to Celery Root
While celeriac can be accommodated into a keto meal plan with prudent approach and controlled portions, you might find it helpful to also know some lower-carb, keto-friendly alternatives.
- Cauliflower: Cauliflower is a versatile, low-carb substitute that often comes to the rescue for many keto enthusiasts. Whether it's riced, mashed, or even used as a pizza crust, this nutritious vegetable can deliver the essence of many traditional carb-heavy dishes. Its net carb content stands at around 2.8g per 100g serving-significantly less than celeriac.
- Broccoli: Broccoli is another low-carb staple that can replace celeriac in a variety of dishes.
- Zucchini: With a net carb content of just 2.1g per 100g serving, zucchini easily fits into a keto menu.
- Celery Root: A less common but effective substitute is celery root.
Selecting a substitute ultimately comes down to your culinary preference, nutritional requirements, and the target dish.
Culinary Uses of Celery Root
Celery root is highly versatile, and it can be eaten raw in salads, roasted, mashed, or blended into soups.
Here’s how to incorporate celeriac into your diet.
- Substitute for Mashed Potatoes: Use celery root as a healthier alternative to traditional mashed potatoes.
- Soups and Stews: Add chopped celery root to soups, stews, and casseroles for added flavor and nutrition.
- Roasted or Boiled: Roast or boil celery root as a side dish.
- Salads and Slaws: Use raw celery root in salads or slaws for a crunchy texture and fresh flavor.
- Celery Root Puree: Make a delicious celery root puree as a side dish or use it as a base for soups and sauces.
- Celery extract: Celery extract can be used in various recipes to provide a concentrated source of celery's health benefits.
Selection, Preparation, and Storage
For optimal flavor, choose a medium-sized celeriac - 3-4 inches (8-10 cm) in diameter - with a smooth, even surface. Avoid large, heavy ones that are discolored or have surface cracks. Be sure that its center isn’t hollow, which is a sign that the celeriac is of poor quality. What’s more, the fresher the vegetable, the stronger its celery flavor.
For optimal shelf life, store celeriac in a plastic bag inside the vegetable compartment of your fridge.
To prepare it for cooking, wash and scrub the vegetable to remove any dirt before cutting off the top and base. Then, carefully remove the rough skin with a sharp knife or a vegetable peeler and chop or slice the flesh. As celeriac discolors very quickly, soak the cut vegetable pieces in cold water and a few lemon slices or a splash of white-wine vinegar.
Cooking Tips
Celeriac can be eaten raw or cooked and prepared as a side dish.
Here are a few serving tips:
- Try it raw - sliced or grated - in salads, coleslaw or French celeriac remoulade.
- Boil and mash the vegetable as an alternative to potatoes or other root vegetables.
- Roast or bake celeriac like potatoes.
- Cook and blend it for soups, sauces, pies and casseroles.
Cut into rough-shaped chunks, celeriac usually boils in around 20 minutes and roasts in around 40 minutes.
Safety Concerns
Celeriac is considered safe for most people. However, some may need to limit or avoid eating this vegetable.
Celery root contains natural carbohydrates, which may not be suitable for very low-carb diets if consumed in large amounts. Some people may experience digestive discomfort or bloating due to its fiber content, especially if consumed in excess. Additionally, celery seeds have diuretic properties and can be effective in treating urinary tract infections, but they may also cause digestive discomfort if consumed in excess. While it provides many essential nutrients, it is not as nutrient-dense as dark leafy greens or other highly concentrated superfoods. Celery root needs to be properly cleaned and peeled, as its rough outer skin can trap dirt, making preparation slightly more time-consuming.
While celery root is generally safe and nutritious, it’s important to be aware of potential risks and allergies associated with its consumption. Some individuals may be allergic to celery, experiencing symptoms such as itchiness or swelling of the mouth and lips. Additionally, celery contains compounds like furanocoumarins and psoralens, which can be toxic in large quantities. These substances can cause skin issues and liver damage if consumed excessively. Therefore, people with known allergies or intolerances to celery should avoid eating celery root and drinking celery juice.
Celery juice has gained popularity in recent years due to its potential health benefits. However, it’s essential to note that the optimal dose of celery juice is unknown, and excessive consumption may cause skin issues and liver damage. It’s also important to be aware of potential interactions with certain medications, such as blood thinners, due to the high vitamin K content in celery.
- Allergic Reactions: Some people may be allergic to celery, which can cause symptoms such as itching, swelling, and digestive issues.
- Interactions with Medications: Celery may interact with certain medications, such as blood thinners, due to its high vitamin K content.
- Pregnancy and Breastfeeding: While celery is generally considered safe during pregnancy and breastfeeding, excessive consumption may cause uterine contractions and affect milk production.
- Emergency Surgery: In rare cases, eating celery may cause a blockage in the digestive tract, which may require emergency surgery.
Celeriac is high in vitamin K, which can affect blood clotting. Therefore, people with blood-clotting disorders who are on medication like warfarin should avoid excessive consumption. In addition, the high levels of potassium and phosphorus in celeriac can make it unsuitable for people on diuretics or with kidney problems. Finally, certain compounds in celeriac, such as bergapten, may stimulate a woman’s womb possibly causing contractions. Therefore, you should not eat large quantities during pregnancy.
If you’re affected by any of these conditions, speak with your healthcare provider about whether eating celeriac is appropriate.
