You do not have to do anything more energtic than simply move through your day to be exposed to a multitude of environmental toxins from Airborne Pollutants, EMF's (Electromagnetic Fields), Endocrine disruptors to Pesticides and Heavy Metals.
While we all carry these toxins in our bodies to a greater or lesser extent, some groups such as children, women (especially pregnant)
and elderly are more affected than others.
Water Needs and Resources
The total amount of water in a man of average weight (70 kilograms) is approximately 40 litres, averaging 60 percent of his total body weight. In a newborn infant, this may be as high as 75 percent of the body weight, but it progressively decreases from birth to old age. Most of the decrease occurring during the first 10 years of life. Also, obesity decreases the percentage of water in the body, sometimes to as low as 45 percent".
So where is Earth's Water for all our needs?
Notice how of the world's total water supply of about 332.5 million cubic miles of water, over 96 percent is saline. And, of the total freshwater, over 68 percent is locked up in ice and glaciers. Another 30 percent of freshwater is in the ground. Fresh surface-water sources, such as rivers and lakes, only constitute about 22,300 cubic miles (93,100 cubic kilometers), which is about 1/150th of one percent of total water. Yet, rivers and lakes are the sources of most of the water people use everyday.
'Let the food be your medicine' was an old saying by Hippocrates (source: 424 B.C Hippocrates). famously known as 'Father of medicine'. It is hard to say how far we are going away from this simple sentence but since 2000 more then 65 % of British public took it seriously and start using food supplements.
So, Why we need food supplements?
Ideally, people should eat a good diet and use supplements to promote good health, reduce the risk of illness or disease and fill dietary gaps. Sometimes it is difficult to fulfilled these dietary gaps just through average diet to reach beneficial amount and supplementation become viable option.
For example Minerals!
We do not manufacture them, so we need them for good work of our entire body system. We changed our Diet completely and we eat more cooked and processed food with less vitamins and minerals. Research review done by Royal Society of Chemistry in 1991 found that food in the UK since 1940 until 1991 have less mineral content (Ca, Mg, Fe, Cu & Zn) in range from 35 - 93 %. At the same time we changed the way of seeding the soil, changing natural mineral profile. Swede for example has had 110% increase of P, Phosphorus since 1940. (source: McCance and Widdowson (1991).
