pH balance and disease
Last Updated Aug 2007
Q: I've been hearing more and more about pH balance pertaining to cancer, heart
disease, pain, etc., and how the more "acidic" the body, the more likely cancer and
other diseases will develop and thrive. What are your thoughts on this?
A: Dear Linda,
The body takes great efforts to maintain the pH of the blood, which is meant to be
relatively constant. However, the diet can either help or hinder those efforts.
Foods that are acidic are protein and grains and starches. On the other hand,
fruits and vegetables are alkaline. The more acid in the diet, the more calcium
that must be extracted from the bones to maintain a constant pH in the blood.
Therefore, your best dietary approach to maintain a balanced pH in the blood is to
eat a moderate protein diet with large quantities of vegetables and fruits. This
is the Zone Diet. Relative to the role of pH in cancer, heart disease, and pain,
it is more a consequence of not controlling silent inflammation than having
anything to do with the pH of the blood or the urine.
