Water does not contain any calories. It also does not contain any significant nutritive value, such as proteins, fats, vitamins or minerals. However, it is important for keeping the body hydrated and healthy.
Although it does not contain nutrients, water is essential for life. The body is made up of 60 percent water, and consuming enough water is important for maintaining the balance of fluid and electrolytes in the body's cells. It is also important for keeping skin hydrated, flushing out toxins in the body and evacuating waste from the bowels for healthy digestive processes. Drinking water instead of high-calorie drinks is a great way to manage calorie intake.
