Even though long, dark green, smooth-skinned garden cucumbers are familiar vegetables in the produce sections of most groceries, cucumbers actually come in a wide variety of colors, sizes, shapes and textures. You'll find white, yellow, and even orange-colored cucumbers, and they may be short, slightly oval, or even round in shape. Their skins can be smooth and thin, or thick and rough. In a technical sense, cucumbers are actually fruits, not vegetables. (Fruits are parts of flowering plants that come from the ovary.) But we've become accustomed to thinking and referring to cucumbers as vegetables.Cucumber juice is a very healthy and versatile drink. Cucumbers have a high content of water and contain amounts of potassium, silica, vitamin A, vitamin C, folate, and chlorophyll, among other nutrients.
