Cucumbers are technically considered berries, not vegetables. However, their green skin still offers some significant health benefits, as does the rest of the cucumber. The vitamins, minerals, and antioxidants in cucumbers provide significant health benefits. For example, cucumber skin is full of beta-carotene, which is part of the reason for its rich green color. The carotene family of pigments are important provitamins. Your body can convert beta-carotenes into vitamin A, which is a critical vitamin for keeping your eyes and skin healthy.
Cucumbers are low in carbohydrates, so they can be a good option for people with elevated blood sugar levels. Early trials suggest that cucumber is one of the most effective plants for not only reducing blood sugar levels but also lowering the risk of hypoglycemia during a blood sugar drop.
An entire cucumber, generally defined as being 8.25 inches long or 300 grams, only has 45 calories. Cucumbers are more than 96% water, so they’re filling and nutritious but not calorie-dense. This high-water, low-calorie combination is great for weight management. Studies have shown that eating foods with low energy density, or few calories per gram, is connected with weight loss in people who are obese.
Cucumbers are full of nutrients that act as antioxidants. These antioxidants may have particularly powerful effects, according to some studies. One such study tested the power of cucumber powder and found that adding cucumber to the diet significantly increases the amount of antioxidant activity in the body. While more studies should be done, cucumbers are a safe way to get more dietary antioxidants easily.
Their mild flavor makes them easy to add to many dishes without affecting the flavor of the food, which makes cucumbers an easy way to add bulk to smaller meals.
