>- the body has a very narrow pH range it can survive in. If this level goes too alkaline or too acidic the person will die.
You must be quoting me as I have said this several times. However, if a person will die at a certain pH, then aren't they almost dead at a point that is close to it? I will tell you right now that this is true.
>- Check reliable sources for the truth, which shows just the opposite
Yes, I have a lot of books in my library, but do not need to look up most biochemical and physiological facts as I am quite familiar.
>- claiming that acidity in the cause of all disease.
The is not one single cause of disease and anyone who thinks so is in error.
>- While you are at it research the dangers of alkalosis.
No need, I have been well aware since the 1960's. Either extreme can be deadly, but even getting somewhere near thoses extremes can cause serious permanent damage if not quickly fixed.
Even being a bit high or low in pH is not good. Again, study physiological optimization. If your body is constantly having to pump out acidity or alkalinity, something is wrong and it needs to be fixed.
