Well, I have good reason to not believe in the acid-alkali theory. On an admittedly solely anecdotal level, I've heard a zero-carber report that he actually was highly acidic (re saliva in the mouth, as I recall)while on a vegan diet before going zero-carb. Plus, the body tends to keep blood  within a very narrow PH range regardless of what one is eating, so I don't see how the body couldn't self-regulate acidity/alkalinity elsewhere. Also, the Inuit didn't have bone-problems and were noted for having the lowest rate of dental caries of any tribe(or was that the 2nd-lowest?)

 

 

From a raw perspective, raw meat has a much lower PH value than cooked meat, and the more processed the meat becomes the more acidic it will be. So a diet of , say, 89% raw animal food and 10% raw plant-food(c 1% being cooked food), like what I'm doing now, would presumably not be that much more acidic than a cooked diet consisting of 65% cooked meat and 35%(raw or cooked) fruit and veg.
