These days, most people carry a drink with them wherever they go. Every food shop, however small, has a fridge packed with bottled beverages. Some people drink large quantities of sugary soft drinks, others can’t get through the day without copious quantities of coffee, and tea drinkers are happy to respond to recent experimental evidence that suggests tea is a healthy source of liquid sustenance for the human body. However, for purposes of hydration, the most popular choice is water.

What is nanotechnology?
The UK Food Standards Agency defines nanotechnology as the manufacture and use of materials and structures at the nanometre scale. A nanometre is one millionth of a millimetre. If you shrink a grain of rice one thousand times, stop for a minute to admire your supernatural size-reducing powers and then proceed to shrink the grain a thousand times again, you will have conjured up a nanoparticle.
Heavy metals are natural components of the earth’s crust; however, certain activities of mankind, such as mining and smelting, have led to them becoming concentrated in the environment, in some areas reaching potentially harmful levels. Other sources such as vehicle emissions, industrial waste and fertilizers also contribute to the accumulation of heavy metals in the soil, atmosphere and surface water.
Heavy metals can be severely detrimental to the human body, having toxic and carcinogenic effects and causing the oxidative deterioration of biological macromolecules. The various metals have been implicated in the development of many diseases, including Alzheimer’s disease, diabetes and several forms of cancer.

There are many options for what to drink, but for most people who have access to safe drinking water, water is the best choice: It’s calorie-free, and it’s as easy to find as the nearest tap.
Water provides everything the body needs—pure H2O—to restore fluids lost through metabolism, breathing, sweating, and the removal of waste. It’s the perfect beverage for quenching thirst and re-hydrating your system.
