Water, even in its natural form contains trace elements, like minerals. Tap water too contains chemicals and potentially dangerous impurities depending on the municipality. One type of purified water without such impurities is distilled water. What is distilled water and how does the process occur?
Distilled water completely lacks anything other than the simple H2O molecules. This type of water is not natural but a man-made result of distillation. Distilling is works by boiling water and capturing the steam that results. The steam, in its lightweight transformed state is free of the impurities which are still weighted down in their solid form. The steam eventually changes its state back into a liquid in a separate tank leaving the bacteria, salts, minerals and synthetic chemicals behind. For this reason distilled water has the least taste compared to other potable waters.
Aside from drinking it, distilled water is often used in research arenas when pure water with a pH of 7 is a must. Mineral and impurities in tap water can build up over time, possibly damaging industrial or home-use equipment with deposits.
Although distilled water is pure, it does not make it necessarily healthy to be consumed on a long term basis. Because it lacks minerals, distilled water can help detox the body by flushing out the extra minerals and toxins- but it can also de-mineralize the body, by flushing rid of too many minerals. This is a controversial claim however, because the minerals in food could exceed what is lost. If concerned, adding a squeeze of lemon can help replenish the water.
A person can set up their own distillery in their garage to provide for their own needs and sell to others. Of course, buying distilled water at a grocery store is also an option, but the gallon jugs cannot be refilled up like a local distiller can do.
