Because there is more water in your body than anything else,
water is the first thing you have to look at in an effort to
improve your health.

How clean is the water that you are drinking? Does it contain 
chlorine and or fluoride? Both are known to be cell killers.
Your body is made up of trillions and trillions of cells. 
Do you want these known cell killers in your body?

Does your water contain inorganic minerals? Want to find out?
Put four liters of water in a pot on the stove and bring to a slow
boil for a few hours until all the water is gone, and then check
the bottom of the pot and see for yourself what you are forcing
your kidneys to filter out of your body.

These inorganic minerals are great for your plants, but are not
good for your body. If they were, your kidneys would not be
filtering them out of your system.
Your body needs organic minerals which we get from the food
that we eat. Our bodies are not meant to eat soil like plants do.

I installed a reverse osmosis system for my drinking water.
