Our bodies are nothing but a constant flow of water. 95% of our blood, 75% of our brain, and even 22% of our bones is water. Water like air is essential for the healthy functioning of our body. We can survive several weeks without food, but not more than a few days without water. (Source: Australian Bottled Water Industry website)
Health and nutrition experts recommend we drink at least 2 litres of water every day. Good quality drinking water should provide us with essential minerals and nutrients. Contaminated water can cause disease.
