The Calorie Breakdown: How Many Calories Are in 1 Small Cucumber?
Cucumbers are celebrated for being a low-calorie food, and for good reason. The main factor behind their minimal calorie count is their extremely high water content, which makes up about 95% of the vegetable. While the exact calorie number can vary slightly based on size and variety, several reliable nutrition sources provide a clear picture of what to expect from a small serving.
Size Matters: Peels and Variations
When assessing how many calories are in 1 small cucumber, it's helpful to consider the typical serving size and the impact of the skin. Data from FatSecret indicates a small (16cm long) cucumber has approximately 19 calories. A slightly larger size, referenced in USDA data via Nutritionix, lists a small cucumber at around 24 calories. A half-cup of sliced cucumber, a common portion size, contains a mere 8 calories, while a whole, larger cucumber can reach up to 45 calories. This small variation highlights that no matter the portion, cucumbers remain a very low-energy food, perfect for dieting or weight management. Importantly, leaving the peel on significantly boosts the nutritional content, including fiber and antioxidants, with only a minimal increase in calories.
Comprehensive Nutrition Facts for a Small Cucumber
Beyond their low-calorie nature, cucumbers offer a surprising array of essential nutrients. When you consume a small, unpeeled cucumber, you are getting more than just hydration. The vegetable provides valuable vitamins, minerals, and plant compounds that contribute to overall health. For instance, a small cucumber can supply a good percentage of the daily recommended intake of vitamins K and C, as well as minerals like potassium and magnesium.
The Importance of the Peel
The peel and seeds are the most nutrient-dense parts of the cucumber. The skin contains insoluble fiber, which promotes healthy digestion, and beta-carotene, an antioxidant that is converted to Vitamin A in the body. Many people peel cucumbers, but this practice removes the majority of the fiber and other key nutrients. To maximize the health benefits, it is recommended to wash the cucumber thoroughly and eat it with the skin on.

Health Benefits Beyond the Low-Calorie Count
Incorporating cucumbers into your diet offers numerous health advantages:
