Human body is made up of approximately 70% water. Most abundant element in our body is oxygen. Carbon is the basic unit of organic molecules and occupies the second position. Around 99% mass of human body is made up of just six elements viz oxygen, carbon, hydrogen, nitrogen, calcium and phosphorous. Water is the universal solvent and exhibits peculiar chemical characteristics compared to other solvents and save our life. Now a days chemically treated water has been used for drinking purpose. The invasion of chemicals in our life starts with the first item used in the morning either as beverages or in the tooth paste.

Tooth paste contains several chemical compounds including titanium dioxide.

In the preparation of food materials, various artificial colorants like sunset yellow, preservatives, baking components (sodium bicarbonate), softening agents, food thickeners and taste enhancers are added. Glutamic acid is a neuro transmitter and monosodium glutamate (MSG) is the common taste enhancer added to food. The above synthesized compounds impart various diseases, side effects, neural disorder and finally leads to mortality.
