Water is essential for the human body to function. The body cannot store water and must have fresh supplies everyday to perform virtually every metabolic process. Babies and elderly are vulnerable to lack of water or dehydration. Not drinking enough water increases the risk of kidney stone and in women urinary tract infections, it can lower your physical and mental performance and can lead to dehydration.
The body can last weeks without food, but only days without water. The body is made up of 50 to 70 percent water. Water forms the the basis of blood, digestive juices, urine and perspiration and is contained in lean muscle, far and bone.

Contents Of Water in Food.
Most food, even those that look hard and dry contains water. The body can get approximately 20 percent of its total water requirement from solid food alone.
The digestion process also produces water as a by-product and can provide around 10 percent of the body’s water requirements. The rest must come from liquids.
