Question:
Is there any evidence that Ph values in the blood change as a part of the aging process, or that the Ph values encourage the aging process. Also can nutrition have an effect on Ph.



Replies:
PH is HIGHLY regulated in the body...if not all sorts of proteins start working poorly...or not at all...:(

Most body fluids are strongly buffered, i.e. they contain electrolytes that resist any change in pH -- HCl in the stomach is an exception. If the pH of blood changes very much in either direction, it is a symptom of serious disease and can be fatal.

Consumption of acidic fruits -- oranges, lemons, etc. -- cause some people to break out with sores in their mouth. It is not clear that this is simply due to a decrease in pH however. It may have to do with how the body metabolizes ascorbic, and citric acid. So nutrition does affect pH, but only indirectly.

I do not know of any direct correlation between pH and the aging process.
