Re: A simple free way to alkalinize the body

 Better oxygenation will not compensate for years of demineralization because of SAD diets.

Respiration is just the primary source of pH balance for the body, but not the only.  Bicarbonate is also a buffer for acidity as are minerals from diet.  The kidneys also help maintain pH.  Bone demineralization is the last resort for countering acidosis, which is why bone demineralization from acidosis is extremely rare.
