The Core Calorie Count: What's in a Whole Cucumber?
The calorie content of a single cucumber is surprisingly low, making it an excellent choice for a snack or meal addition without significantly impacting your daily calorie goals. According to nutritional data from the USDA, a large, whole cucumber measuring around 8.25 inches and weighing about 301 grams contains approximately 45 calories. For a smaller or medium-sized cucumber, the calorie count will be proportionately lower, often falling between 15 and 30 calories. Most calories come from carbohydrates, specifically natural sugars and fiber, while protein and fat content are negligible.
Detailed Nutritional Breakdown
While calories are a key consideration, the true value of a cucumber lies in its rich nutritional profile. The high water content is its most prominent feature, making it a fantastic hydrator. The cucumber is a source of several essential vitamins and minerals.
Key Nutrients in Cucumbers
A large, unpeeled cucumber provides several nutrients:
- Vitamin K: Supports blood clotting and bone health.
- Potassium: Supports healthy blood pressure regulation.
- Vitamin C: An important antioxidant.
- Fiber: Aids in digestion.
- Antioxidants: Help fight off harmful free radicals.
How Preparation Affects Calories and Nutrients
Preparation can slightly alter a cucumber's nutritional content. The peel and seeds are the most nutrient-dense parts, containing fiber and beta-carotene. Peeling removes a small amount of both calories and fiber. For example, a single cup of sliced cucumber with the peel has about 16 calories, while the same amount peeled contains closer to 14 or 15 calories. Eating the cucumber unpeeled after thoroughly washing it is recommended for maximum health benefits.
Comparison: Cucumber Calories vs. Other Snacks

| Pretzels | 1 oz (28g) | ~100 | Low in fiber and nutrients, high in sodium |
| Celery | 1 cup, chopped (101g) | ~16 | Very low calorie, also high water content |
