A 100-gram serving of cucumber, which is roughly equivalent to two-thirds of a medium cucumber, contains a remarkably low number of calories, typically ranging from 12 to 16 kcal. This minimal caloric impact is largely due to its high water content, which makes up about 95% of its weight. While cucumbers are not a primary source of macronutrients like protein or fat, they offer several beneficial vitamins and minerals that contribute to a healthy diet. This article will delve into the precise caloric value, nutritional composition, and health benefits of adding this refreshing vegetable to your meals.
The Breakdown of Calories in a 100g Cucumber
The calories in a 100-gram cucumber are primarily derived from its carbohydrates, though the amount is very small. Most nutrition databases report a figure close to 15 calories for 100g of raw, unpeeled cucumber. It is important to note that peeling the cucumber can slightly alter its nutritional value, as some of the fiber and vitamins are concentrated in the skin. For instance, a peeled, raw cucumber may contain slightly fewer calories and nutrients per 100g compared to an unpeeled one. The negligible fat content and low protein levels mean that the calorie count is predominantly influenced by its simple sugars and a small amount of dietary fiber.
Nutritional Information per 100g
Beyond just the low calorie count, a 100g serving of cucumber provides a small but significant source of other nutrients, particularly when consumed with the skin.
- Vitamins: Cucumbers contain a notable amount of vitamin K, which is essential for blood clotting and bone health. They also provide some vitamin C, an antioxidant that helps protect cells from damage. Trace amounts of B vitamins, including B1, B5, and B7, are also present.
- Minerals: Key minerals include potassium, which helps regulate fluid balance and blood pressure, as well as smaller quantities of magnesium, phosphorus, and manganese.
- Hydration: As a water-dense food, cucumbers are excellent for promoting hydration, especially during warm weather or after exercise.
- Antioxidants: The presence of antioxidants, such as flavonoids and lignans (especially in the skin), helps combat oxidative stress and may lower the risk of chronic diseases.
Culinary Applications and Health Benefits
Because of their low-calorie profile and refreshing crunch, cucumbers are a versatile ingredient that can be incorporated into many meals. They add texture and flavor to salads, sandwiches, and wraps without piling on calories. For those seeking to increase their vegetable intake or manage their weight, cucumbers serve as a filling and healthy snack.
- Weight Management: The high water and low-calorie content of cucumbers can help increase satiety, making you feel fuller without consuming excess calories. This can be a useful tool for weight loss efforts.
- Skin Health: The hydrating properties and antioxidants in cucumbers are beneficial for skin health, both when consumed and applied topically. They can help soothe sunburn and reduce puffiness.
- Blood Sugar Control: As a non-starchy vegetable, cucumbers have a low glycemic index, which helps prevent sharp spikes in blood sugar levels. This makes them a good option for people managing diabetes.
- Bone Health: The vitamin K in cucumbers is a key nutrient for maintaining strong bones and supporting healthy blood clotting.
Cucumber Types: Nutritional Comparison (Per 100g)
While the nutritional differences between cucumber varieties are generally minor, here is a comparative overview based on standard nutritional data.

| Protein | ~0.7 g | ~0.6 g | Both contain a very small amount of protein. |
| Fat | ~0.1 g | ~0.1 g | Negligible fat content in both. |
| Vitamin K | High | High | Both are good sources of Vitamin K. |
How to Maximize the Nutritional Benefits
To get the most nutritional value from your cucumber, it is often recommended to consume it with the peel. The skin contains valuable fiber, vitamin A, and other antioxidants. Be sure to wash the cucumber thoroughly to remove any dirt or pesticide residue. Using it in various recipes can also enhance your nutrient intake.
