For those mindful of their caloric intake, celery is a consistent star performer in the produce aisle. It provides a satisfying crunch and a boost of nutrients with minimal energy cost. But the specific calorie count of a single stalk can vary based on its size, so for accurate tracking, it's helpful to know the breakdown.
Celery's Calorie Count by Size
The calorie count for celery is minimal, with size being the primary factor influencing its energy content. The USDA provides precise nutritional data for various serving sizes.
- Small Stalk: A small stalk of celery, which is about 5 inches long, contains approximately 2 to 3 calories.
- Medium Stalk: A medium stalk, measuring between 7.5 and 8 inches, typically has around 5.6 to 6.4 calories. This is the most common size found in stores.
- Large Stalk: A large stalk, measuring up to 12 inches long, can contain between 9 and 10 calories.
- Chopped Celery (1 Cup): For recipes that call for chopped celery, one full cup contains about 14 to 16 calories.
These numbers illustrate why celery is a popular choice for low-calorie snacks and a foundation for many healthy dishes. The minimal calorie count means you can consume a significant amount to feel full without adding much to your overall daily intake.
Beyond the Calories: Celery's Nutritional Profile
While the calorie content of celery is its most famous attribute, its nutritional benefits extend far beyond a low number. Celery is a hydrating powerhouse, composed of almost 95% water, which helps in maintaining hydration, especially during warmer months. It also contains a valuable mix of micronutrients and other beneficial compounds.
Key Nutrients in a Medium Stalk of Celery
- Vitamins: It is an excellent source of Vitamin K, crucial for blood clotting and bone health, providing about 10-17% of the daily recommended intake. It also offers smaller amounts of Vitamin A and C.
- Minerals: A single stalk contains notable amounts of potassium, which is vital for regulating blood pressure, and a small amount of calcium.
- Fiber: Celery provides dietary fiber, both soluble and insoluble, which promotes digestive health and increases satiety.
- Antioxidants and Phytonutrients: Celery is loaded with antioxidants like flavonoids (apigenin and luteolin) and phytonutrients that help protect cells from oxidative damage and reduce inflammation.
Is Celery a 'Negative Calorie' Food?
This is a persistent dietary myth. While celery is very low in calories, it is not a zero-calorie or 'negative-calorie' food. The myth suggests that the body burns more calories digesting celery than it gains from eating it. However, the energy cost of digestion (thermic effect of food) is much lower than the caloric energy celery provides. A medium stalk of celery yields about 6 calories, while your body uses a fraction of that to digest it, resulting in a net positive calorie intake. Despite this, its high water and fiber content means it fills you up quickly, making it a valuable tool for appetite management in a calorie-controlled diet.
Raw vs. Cooked Celery: Calorie and Nutrient Effects
How you prepare celery can slightly alter its nutritional value, including its caloric availability.
- Raw: When eaten raw, celery's tough fibrous structure means the body expends slightly more energy breaking it down. This is when it offers its highest crunch and hydrating effects.
- Cooked: Cooking celery, such as in soups or stews, breaks down its fibrous cellulose, making its calories more readily available for absorption. While the caloric change is small, and it's still a low-calorie addition, it's worth noting. Cooking can also reduce the levels of some heat-sensitive nutrients like Vitamin C, though other beneficial compounds remain stable.
Comparison Table: Celery vs. Other Low-Calorie Veggies
| Feature | Celery (Medium Stalk) | Cucumber (1/2 Cup Sliced) | Lettuce (1 Cup Shredded) | Green Bell Pepper (1/2 Cup Chopped) |
|---|---|---|---|---|
| Calories | ~6 kcal | ~8 kcal | ~5 kcal | ~15 kcal |
| Water Content | ~95% | ~96% | ~95% | ~92% [General Knowledge] |
| Dietary Fiber | ~0.6 g | ~0.3 g [General Knowledge] | ~0.5 g [General Knowledge] | ~1 g [General Knowledge] |
| Vitamin K | ~11.7 mcg | ~8.5 mcg [General Knowledge] | ~24 mcg [General Knowledge] | ~6 mcg [General Knowledge] |
Note: Nutritional information can vary slightly based on source and specific vegetable type. The above is an approximate comparison based on raw values.
Practical Ways to Add Celery to Your Diet
Celery's versatility means it can be integrated into many different dishes, from snacks to full meals.
- Classic Snacking: A simple, crunchy snack on its own or paired with low-calorie dips like hummus.
- Ants on a Log: A timeless classic, filled with peanut butter or cream cheese and topped with raisins.
- Soups and Stews: A core ingredient in a mirepoix, celery adds a savory, aromatic flavor base to many soups and stews.
