Water

Water is a very important essential nutrient. The body can go for a few weeks without food but can only survive for a few days without water. Water makes up about
60% of an adult’s body weight. In the body, water is the fluid in which all life processes happen.

Examples of Water’s attributions in the Body:

  • Carries nutrients and waste throughout the body
  • Maintains the structure in large molecules
  • Assists in metabolic reactions
  • Acts as a solvent for minerals, vitamins, amino acids and glucose
  • Serves as a lubricant and cushion between joints and inside the eyes
  • Performs as a amniotic sac surrounding the fetus in the womb
  • Helps to regulate body temperature
  • Sustains blood volume


Water Needs

The amount of water needed by the body depends on diet, activity, environmental temperature and humanity. Men generally need more water than women. Adults usually need more water than children. The recommended amount of water needed for a person who expends 2000 calories a day is 8-12 cups. The amount and type of water a person drinks may have a positive or negative effect on health. Water intoxication is rare but possible. Water intoxication occurs when the body’s water contents are too high in all body fluid compartments.
