The cucumber is mostly water and has very little energetic value. It is very low in carbohydrates, and even lower in proteins and lipids, plus it is very refreshing, and so it is often included in low-calorie diets. Moreover, its high content in potassium and water make it an excellent natural diuretic.Cucumbers are generally soaked in salty water to remove a little of their natural water content. They segregate water and dilute (melt) seasonings. Unpeeled cucumbers have a higher nutritional content in fiber and Vitamin A, that can be lost when they are peeled.The cucumber originated in tropical Africa where it was known in ancient times by the Egyptians and was later cultivated by the Greeks and Romans.
