While I am certainly not indoctrinated in ph principles, at one time they did make good sense to me. It has been proven that it is hard for disease to thrive in a well oxygenated body. But thanks to you I have learned that the body doesn't acheive optimal ph levels, or become well oxygenated, or however you want to describe it, by eating alkaline foods or using oxygen therapy or any of that other jazz (although it may be a temporary fix), one gets it when their eliminatory systems and blood circulation are functioning properly and that only happens when the liver is healthy. I am still learning but I now know ph should not be the focus. So thank you Charlie, and thanks for that explanation above too.
