I got turned on the pH phenomena early on.. I heard a presentation by none other than Tony Robbins about how alkaline food would cause the blood pH to combat certain ailments..
then I found a book called the pH miracle by Robert O. Young PhD. and Shelley Redford Young. This book was a shock, as it outlined the pH balance that we all need to strive for. Most importantly it threw a monkey wrench in all I "thought I knew" about the biological process.
