And Food Combining:Disturbances of acid-base balance
Deviations of the blood plasma pH from its normal value of 7.4 by more than about ±0.1 can be very serious. These conditions are known medically as acidosis and alkalosis. They can be caused by metabolic disturbances such as diabetes and by kidney failure (in which excetion of H2PO4–, for example, is inhibited.)
Numerous other processes lead to temporary unbalances. Thus hyperventilation, which can result from emotional upset, leads to above-normal loss of CO2, and thus to alkalosis. Similarly, hypoventilation can act as a compensatory mechanism for acidosis.
On the other hand, retention of CO2 caused by bronchopneumonia, for example, can give rise to acidosis. Acidosis can also result from diarrhea (loss of alkaline fluid from the intestine,) while loss of gastric contents by vomiting promotes alkalosis.
The idea, widely promoted on commercial quackery sites, that people need "alkaline" water supplements to "balance body pH" or "neutralize" acidic foods, has no scientific support. It is pure, deceptive sales hype.
Why do I waste my time on this stuff?
Chemistry is my favorite subject, and I hate to see it misused to confuse, mislead or defraud the public.
