Calorie and Nutrition Breakdown for 100g of Cucumber with Skin
Understanding the calorie count and nutritional profile of the foods we eat is key to managing a healthy diet. Cucumber, especially with its skin, is a nutritional powerhouse that offers more than just hydration. A standard 100-gram serving of raw cucumber with the skin intact is one of the lowest-calorie foods available.
The Calorie Content Explained
At approximately 16 calories per 100 grams, cucumber is a remarkably low-calorie food. This is largely due to its high water content, which makes up about 95% of its total weight. The low-calorie density means you can eat a significant volume of cucumber to feel full and satisfied, making it an excellent choice for weight management. For context, a standard 21cm cucumber (roughly 300g) would only contain about 45 calories.
Why Keeping the Skin On Matters
While the caloric difference between a peeled and unpeeled cucumber is negligible, keeping the skin on offers notable nutritional advantages. The cucumber skin is where a significant portion of its dietary fiber and Vitamin K is concentrated. Removing the skin strips away these valuable components, diminishing the overall nutritional impact.
Benefits of eating the skin include:
- Higher Fiber Intake: The fiber in the skin aids in digestion, promotes regularity, and contributes to a feeling of fullness.
- Increased Vitamin K: The skin significantly boosts the cucumber's Vitamin K content, a nutrient essential for bone health and proper blood clotting.
- More Antioxidants: The vibrant green color of the skin is an indicator of its antioxidant content, including beta-carotene, which the body converts into Vitamin A.
- Additional Minerals: The skin also contains other minerals, including some calcium, magnesium, and potassium.
Nutritional Comparison: Cucumber with Skin vs. Peeled
To highlight the importance of consuming cucumber with its skin, here is a comparison of the key nutritional components per 100g, based on USDA data.
| Nutrient | Raw Cucumber (with skin) per 100g | Raw Cucumber (peeled) per 100g |
|---|---|---|
| Calories | ~16 kcal | ~15 kcal |
| Water | ~95.5 g | ~96.7 g |
| Fiber | ~0.5 g | ~0.3 g |
| Vitamin K | ~24 mcg | ~17 mcg |
| Vitamin C | ~2.8 mg | ~2.8 mg |
| Potassium | ~170 mg | ~147 mg |
| Magnesium | ~10 mg | ~7 mg |
As the table shows, the skin provides a measurable increase in fiber, Vitamin K, potassium, and magnesium, with only a minor caloric change. This confirms that the nutritional payoff of eating the skin far outweighs any minimal difference in calories.
