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.

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.
