Be very careful with alkaline water. ,Yes, you change the ph in your body to prevent cancer. But...it takes years in small doses to change the ph successful. If you change it to fast, you destroy your kidneys, liver and much more. Not worth the risk. Just saying. I asked my 2 oncologists, and my stem cell transplant team which consists of several hematologist's, which is where I got to info from directly. I was going to try drinking alkaline water for the same reason until they told me the down side of it.
