Minerals are essential for the basic functions of the human body to take place. They help to control bone growth, regulate fluids, normalize nerve and muscle functions, keep up metabolism, grow connective tissues, and so much more.
However, a big misconception is that that we obtain minerals from our drinking water. This is actually not true because, in reality, the main source of minerals is always from our food and diets, not from our drinking water. Because in order to receive enough minerals for our body, we need to drink a bathtub amount of water everyday! Not very feasible. We are sure that your doctor will not prescribe you a "bathtub of water" if you are deficient in minerals, right?
Therefore watch out for the water products which claims that they can take out ALL of the bad contaminants and leave you only the good stuff (healthy minerals) in the water. There is no real purification method that can be selective and leave you only the "good" stuff. When filters leave you the "good" stuff, they actually leave you "most" of the stuff in the water. "Most of the stuff" meaning besides calcium and magnesium, they also leave fluoride, pesticides, hard metals, radioactive materials, chemicals, and pharmaceutical drugs. In this era of pollution where water contains much more disease-causing contaminants than beneficial minerals, it makes sense that the water we drink should be as pure and clean as possible.
So remember to eat healthy and enjoy a variety of vegetables and grains everyday which will provide you with the beneficial organic minerals to stay healthy the natural way.
