Water

Nutrients are those elements from food and drink that perform a sustaining or metabolic function when taken inside our bodies.

Essential nutrients must be supplied from an outside source because they cannot be made by the body in sufficient amounts. Water is an essential nutrient. Without it human life cannot survive. Water deprivation kills faster than lack of any other nutrient.

If water is something you rarely think about, you are not alone. It is seldom considered a nutrient. Many people don't realize the important part water plays in major body functions.
