Water

• Needed to regulate body temperature, cushions joints and make up our blood.

• The human body is two-thirds water.• Water is an essential nutrient that is involved in

every function of the body. • Water helps transport nutrients and waste

products in and out of cells. • Water is necessary for all digestive, absorption,

circulatory, and excretory functions • Water is needed for the utilization of the water-

soluble vitamins. • It is needed for the maintenance of proper body

temperature.
