One cup (101g) of chopped celery contains just 16 calories, 0.4g protein, 3.5g carbohydrates, 1.6g fiber, and provides 24% of your daily vitamin K needs. This low-calorie vegetable is 95% water and naturally sodium-free, making it ideal for hydration and weight management diets.
Ever wonder what those numbers on a celery nutrition label really mean for your health? Understanding celery's nutritional profile goes beyond just counting calories—it reveals why this crunchy vegetable has become a staple in weight management diets, hydration strategies, and balanced meal planning. Whether you're tracking macros, managing blood pressure, or simply looking to boost your vegetable intake, knowing exactly what's in celery helps you make informed dietary choices.
Decoding the Standard Celery Nutrition Facts Panel
When you pick up a package of pre-cut celery sticks, you'll typically find a nutrition label showing values per serving (usually 1 cup or 101g). Let's break down what each component means for your daily nutrition goals:
| Nutrient | Amount per 1 Cup (101g) | % Daily Value* |
|---|---|---|
| Calories | 16 | <1% |
| Total Fat | 0.2g | 0% |
| Sodium | 80mg | 3% |
| Total Carbohydrate | 3.5g | 1% |
| Dietary Fiber | 1.6g | 6% |
| Sugars | 1.3g | - |
| Protein | 0.4g | 1% |
| Vitamin K | 32.2mcg | 24% |
| Vitamin C | 3.1mg | 3% |
| Potassium | 260mg | 6% |
*Percent Daily Values are based on a 2,000 calorie diet. Your daily values may be higher or lower depending on your calorie needs.
This nutritional profile comes directly from the USDA FoodData Central database, the most current and reliable source for food composition information in the United States (USDA, 2023). Unlike many packaged vegetables, celery naturally contains no added sodium—those 80mg come from the plant itself.
What These Numbers Mean for Your Health
The magic of celery lies in its exceptional water content (95%) combined with meaningful micronutrients. While the calorie count seems almost too good to be true, understanding how these nutrients function in your body reveals celery's true value:
Vitamin K Powerhouse
That 24% daily value for vitamin K isn't just a number—it represents one of celery's most significant nutritional contributions. Vitamin K plays a crucial role in blood clotting and bone metabolism. For those not taking blood thinners, incorporating celery regularly supports these vital functions. Just one cup provides more vitamin K than an equivalent serving of cucumbers or zucchini.
The Sodium Paradox
Despite containing 80mg of sodium per cup, celery remains a smart choice for blood pressure management. This natural sodium content works in concert with celery's substantial potassium levels (260mg per cup), creating a favorable sodium-potassium ratio that supports healthy blood pressure regulation. Research published in the Journal of Agricultural and Food Chemistry confirms that celery's phytonutrients, particularly phthalides, contribute to its blood pressure-lowering effects beyond just its mineral content (Tung et al., 2008).
Celery Nutrition Compared to Common Vegetables
Understanding celery's nutritional value becomes clearer when comparing it to similar vegetables. This fact comparison shows where celery excels and where other options might serve different dietary needs better:
| Nutrient | Celery (1 cup) | Cucumber (1 cup) | Carrots (1 cup) | Broccoli (1 cup) |
|---|---|---|---|---|
| Calories | 16 | 16 | 52 | 55 |
| Fiber | 1.6g | 0.5g | 3.6g | 2.4g |
| Vitamin K | 24% | 10% | 16% | 116% |
| Vitamin A | 2% | 1% | 106% | 11% |
| Potassium | 6% | 4% | 11% | 8% |
This comparison reveals celery's unique nutritional niche—it's not the most vitamin-dense vegetable, but its extremely low calorie count combined with meaningful vitamin K and potassium makes it ideal for specific dietary goals. Unlike carrots, which are high in vitamin A but also higher in natural sugars, celery provides hydration and crunch with minimal caloric impact.
Practical Applications: Using Celery Nutrition in Your Diet
Knowing celery's nutritional profile is only valuable if you can apply it to real-world eating habits. Here's how to maximize celery's benefits based on your specific health goals:
For Weight Management
With only 16 calories per cup, celery makes an excellent volume food for those watching their calorie intake. Registered dietitians often recommend the 'crunch factor' of celery to satisfy snack cravings without significant caloric impact. Pair celery sticks with 2 tablespoons of natural peanut butter (190 calories) for a balanced snack providing protein, healthy fats, and fiber that keeps you full longer.
For Hydration Support
At 95% water content, celery contributes significantly to your daily fluid needs. During hot weather or after exercise, celery provides hydration plus electrolytes like potassium that help maintain fluid balance. Unlike plain water, celery's natural sodium content enhances hydration efficiency—making it particularly valuable for athletes or those in warm climates.
For Blood Pressure Management
The combination of potassium, calcium, and magnesium in celery supports healthy blood pressure levels. For those monitoring sodium intake, remember that celery's natural sodium content (80mg per cup) is substantially lower than processed foods. One stalk contains just 32mg sodium—less than 2% of the American Heart Association's recommended daily limit of 1,500mg for those with hypertension.
Important Context: When Celery Nutrition Varies
Several factors can affect celery's nutritional content, creating important context boundaries for interpreting nutrition labels:
- Storage conditions: Celery loses vitamin C rapidly when stored at room temperature. Refrigeration preserves nutrients better—after one week in the refrigerator, celery retains about 85% of its original vitamin C content (USDA Postharvest Research, 2018)
- Preparation method: Raw celery maintains all its water-soluble vitamins, while cooking can reduce vitamin C content by up to 40%. However, cooking may increase the bioavailability of certain antioxidants
- Organic vs conventional: Studies show minimal nutritional differences between organic and conventionally grown celery, though pesticide residue levels differ significantly
- Regional growing conditions: Soil composition affects mineral content—celery grown in potassium-rich soil will have higher potassium levels
Special Considerations for Specific Diets
Celery fits well into most dietary patterns, but certain considerations apply:
Keto and Low-Carb Diets
With just 3g net carbs per cup, celery works well in ketogenic and low-carb diets. Its high water content and crunch make it an excellent substitute for higher-carb vegetables. Add celery to tuna salad or egg salad for texture without significantly impacting carb counts.
Low-Sodium Diets
Despite containing natural sodium, celery remains appropriate for most low-sodium diets. One cup provides only 3% of the daily value, significantly less than processed foods. For those on strict sodium restriction (1,500mg/day), celery's contribution remains minimal compared to other dietary sources.
Allergy Considerations
Celery allergy affects approximately 0.1-0.2% of the population, primarily in Europe. Those with pollen-food syndrome (oral allergy syndrome) may experience mild reactions to raw celery, particularly during birch pollen season. Cooking celery typically eliminates these reactions by denaturing the proteins responsible.
Maximizing Celery's Nutritional Benefits
To get the most from celery's nutritional profile, consider these practical tips:
- Store celery upright in water in the refrigerator to maintain crispness and nutrient retention
- Include the leaves—they contain significantly higher concentrations of vitamin K and calcium than the stalks
- Pair celery with healthy fats (like olive oil or avocado) to enhance absorption of fat-soluble vitamins
- Use celery in soups and stocks—the nutrients leach into the liquid, creating a nutrient-rich base
- For maximum crunch and hydration, consume celery within one week of purchase
