Nutrition and Information Guide: Water

About the drink water, nutritional information guide, uses, effects of deficiency or overdose, good sources of water.


Use in the Body: Necessary for all building functions in the body. Water dissolves and transports other nutrients, and thus acts as a carrier in the processes of digestion, absorption, circulation, and excretion. It also helps regulate body temperature.

Deficiency May Lead to: Dehydration.

Overdose May Lead to: Edema (swelling), usually caused by a kidney disorder rather than excessive drinking. Prolonged intake of soft water may significantly contribute to hypertension, hardening of the arteries, and apoplexy (brain hemorrhage); the presence of cadmium in soft water may be the reason.

Notes: Water, an essential constituent of all body cells, comprises over 50% of the human body. Its intake is regulated by a sensation of thirst. There are basically 3 kinds of drinking water:

1) Hard water--contains calcium, magnesium salts, and other materials.

2) Soft water--contains sodium, which has replaced the calcium and magnesium salts. Acidic and corrosive, soft water often dissolves and contains the metal of the pipes through which it passes. Often contains copper, iron, zinc, and cadmium.

3) Distilled water--pure water that has had all the minerals removed by a steam process.

Industrially polluted water has become a serious problem in this country. Most municipal drinking water has been generously laced with chlorine for purification and fluorine to help prevent tooth decay. Water may be beneficial for swollen glands, cystitis, constipation, and gallstones.

Best Sources: Spring water, tap water, milk, beverages, fruits, and vegetables.
