The Simple Answer: Yes, But Not Many
For anyone monitoring their carbohydrate intake, it's reassuring to know that celery is an extremely low-carb vegetable. A single medium stalk (approximately 40 grams) contains only about 1.2 grams of total carbohydrates. Even a whole cup of chopped celery has just around 3 grams of total carbs, and a significant portion of that comes from fiber. This low-density carbohydrate profile is a major reason why celery is a staple in many low-carb and ketogenic dietary plans.
Total Carbs vs. Net Carbs
When discussing carbohydrates, it's crucial to understand the difference between total carbs and net carbs. Total carbohydrates represent all carbohydrates in a food, including fiber and sugars. Net carbs, which are more relevant for those on specific diets like keto, are the total carbs minus the fiber. Because fiber is indigestible, it does not raise blood sugar levels in the same way as other carbohydrates.
For a medium celery stick with 1.2 grams of total carbohydrates, about 0.6 grams is dietary fiber. This leaves a net carb count of just 0.6 grams. When considering a full cup of chopped celery, which has 3 grams of total carbs, and about 1.6 grams of fiber, the net carb total is only 1.4 grams. The extremely low net carb count is what makes celery a worry-free option for low-carb eaters.
Is Celery Keto-Friendly?
Because celery contains so few net carbs, it is considered perfectly acceptable for the ketogenic diet. The typical ketogenic diet limits daily carbohydrate intake to a low number, often less than 50 grams per day. The negligible amount of digestible carbs in celery means you can enjoy a satisfying, crunchy snack without fear of disrupting ketosis. Celery also helps to combat dehydration, which can be a common issue when starting a keto diet, due to its high water content. It’s a great vehicle for other higher-fat, keto-friendly foods like cream cheese, guacamole, or nut butter.
Beyond the Carbs: The Nutritional Power of Celery
While its low-carb nature is a major draw, celery's benefits extend far beyond that. This crisp vegetable is a powerhouse of essential vitamins, minerals, and antioxidants.
Some of the key nutrients include:
- Vitamin K: Important for blood clotting and bone health.
- Vitamin A: Contains beta-carotene, an antioxidant that supports vision.
- Vitamin C: A powerful antioxidant that supports the immune system and is important for collagen synthesis.
- Potassium: An essential mineral for heart health, nerve function, and blood pressure regulation.
- Folate: Critical for cellular function and is especially important during pregnancy.
- Antioxidants: Celery contains numerous antioxidants, including flavonoids like apigenin and luteolin, which have anti-inflammatory properties.
Its high water content (95%) also makes it an excellent choice for staying hydrated. The fiber content supports digestive health, promoting regular bowel movements and feeding beneficial gut bacteria.
Raw vs. Cooked: How Preparation Affects Glycemic Index
An important factor to consider is how preparing celery can change its nutritional profile, specifically its glycemic index (GI). The GI measures how quickly a food raises blood sugar levels. Raw celery has a very low GI of 15, making it a great choice for managing blood sugar. However, cooking can significantly alter this. The GI for cooked celery can increase dramatically, with some sources reporting a value as high as 85 for boiled celery. For this reason, those focusing on blood sugar control or a very low-GI diet should stick to eating raw celery.
Celery vs. Other Low-Carb Vegetables: A Comparison
To put celery's low-carb status in perspective, here's how it compares to other popular low-carb vegetables. Values are approximate for one cup of chopped, raw vegetable:
| Vegetable | Total Carbs (g) | Fiber (g) | Net Carbs (g) |
|---|---|---|---|
| Celery | 3.0 | 1.6 | 1.4 |
| Cucumber | 4.0 | <1 | >3.0 |
| Chopped Red Bell Pepper | 9.0 | 3.0 | 6.0 |
| Raw Spinach | 1.0 | <1 | >0.0 |
| Zucchini | 4.0 | 1.0 | 3.0 |
This table illustrates that while other vegetables may be low-carb, celery consistently offers a very low net carb count, making it a safe bet for those counting every gram.
Incorporating Celery into a Healthy Diet
There are countless ways to enjoy the satisfying crunch and flavor of celery. Its versatility makes it a great addition to almost any meal plan.
- Snack Time: Pair celery sticks with keto-friendly dips like guacamole, hummus, or full-fat cream cheese. For a classic combination, spread peanut or almond butter on stalks and add a few raisins for a touch of sweetness.
- Salads and Sides: Add a refreshing crunch to salads by dicing celery and combining it with other ingredients. For a healthy and filling side dish, braise celery with herbs.
- Soups and Stews: Celery is a foundational aromatic vegetable in many soups and stews, including the French mirepoix and Cajun 'holy trinity'. It adds depth of flavor and texture.
- Juicing: While juicing removes some of the fiber, celery juice is still very low in carbs and provides many vitamins and minerals. However, be mindful of the portion size, as the carbs can become more concentrated.

Conclusion: The Bottom Line on Celery Carbs
In short, there are carbs in celery sticks, but they are incredibly low, especially when considering the net carb count. This makes celery an excellent choice for anyone on a low-carb diet, including keto. Its nutrient density, high water content, and valuable antioxidants provide a host of health benefits beyond its low-calorie profile. Whether you're using it as a crunchy vessel for dips, a flavor base for soups, or a simple hydrating snack, celery is a versatile and healthy addition to any balanced diet. As with any food, pairing it with complementary nutrient-dense options ensures you get a well-rounded nutritional boost.
