More and more research studies are showing that the breakdown of meat during digestion causes an acidic environment. Cancer thrives on acid.  Most plant based foods are alkaline.  Also the body will take calcium out of the bones in order to bring the body’s pH level back into balance.  This process causes osteopenia and osteoporosis, both diseases which are very high in the U.S. Research shows that those who eat more of a meat based diet have higher rates of diabetes, cardiac disease, stroke, and cancer growth.  Read the book The China Study for more information about this.
