About Cucumber
One cup of sliced cucumber with peel provides approximately 16 calories, 0.7 grams of protein, 3.8 grams of carbohydrate, 0.1 grams of fat, and 0.5 grams of fiber. It contains about 3.3 grams of net carbohydrate and is composed of roughly 95 percent water.
Cucumber nutrition includes modest amounts of vitamin K, vitamin C, potassium, magnesium, manganese, and several trace minerals. It is not as micronutrient-dense as dark leafy or cruciferous vegetables, but it is valuable for hydration, food volume, texture, and dietary variety.
Cucumber can improve satiety by increasing the physical volume of salads, sandwiches, wraps, and snack plates for very few calories. Pair it with a protein-rich dip or filling to create a snack that lasts longer than cucumber alone.

Keep the peel when it is clean and tender because it contributes fiber and vitamin K. Use cucumber with hummus, Greek yogurt dip, tuna, eggs, tofu, or nuts so the snack provides protein or healthy fat in addition to hydration and crunch.
