How Many Calories in a Cucumber Slice? Understanding the Nutritional Value
A single, average-sized slice of cucumber contains approximately less than one calorie. Considering this, the caloric contribution of cucumbers to a diet is considered to be negligible and significantly impactful on hydration and overall health.
The Humble Cucumber: More Than Just a Garnish
The cucumber, Cucumis sativus, is often relegated to the side of a plate or a refreshing addition to water. However, beneath its mild flavor lies a wealth of benefits and a nutritional profile that deserves more attention than it often receives. This article will delve into the caloric content of cucumber slices, exploring the nutritional value of cucumbers, their health benefits, and common ways to incorporate them into a balanced diet. We’ll also address frequently asked questions to provide a comprehensive understanding of this versatile vegetable.
Nutritional Breakdown of Cucumbers
Cucumbers are predominantly water. This high water content makes them incredibly low in calories. A typical medium-sized cucumber, roughly 300 grams, contains only about 45 calories. Since we are discussing individual slices, the caloric content drastically decreases.
- Water Content: Approximately 96% water.
- Vitamins: Vitamin K, Vitamin C, and some B vitamins.
- Minerals: Potassium, magnesium, and manganese.
- Fiber: Small amounts of dietary fiber.
- Other Nutrients: Antioxidants, including cucurbitacins.
A table comparing the nutritional content of a whole cucumber versus a single slice will give a clearer picture:
