1 Water, making up to nearly 70% of our body weight, is the most important essential nutrient that we cannot live without for more than a few days.
2 In comparison to the other five essential nutrients -- carbohydrates, fats, proteins, vitamins, and minerals, water plays a less obvious role. It does not generate energy as carbohydrates, fats, and proteins do. It does not keep our eyes healthy as vitamin A does. Furthermore, it does not make our bones strong as mineral calcium does. In a way, water is like a puppet master that runs the show from behind the curtain. Although water makes no energy, it helps dissipate heat, a by-product of the energy production. Through perspiration, excess heat gets expelled and our body temperature gets regulated.
3 Aside from preventing us from being overheated, water also carries out three other vital functions to ensure that our bodies perform properly. The first is to deliver nutrients and oxygen to cells around our bodies, the second is to lubricate our joints and organs, and the third is to remove body wastes through sweat or urine.
