"This is why people should stop trying to force the body in to an alkaline condition. It just ends up creating other health problems and draining the wallet with overhyped and over priced alkalinizing gimmicks."
Its not about trying to FORCE the body but rather allowing it to return back to its normal state. For example if the stomach lacked its acidic pH, shouldn’t it be investigated and returned back to normal acidic pH? Same with internal system.

The alkalinizing proponents suggest that to return the internal system back to its slightly alkaline state one must replace many of the cooked meals with fresh greens and fruits. That is their main suggestion. Minerals (non-synthetic) and herbs can help but diet is most important. Plus a healthy lifestyle that include exercise, lots of fresh air, etc is of course beneficial. Those that eat poor diet and poor lifestyle tend to have imbalances in their internal system pH.
