Q: I have been doing a lot of research on the alkaline versus acidic effect of fruits and vegetables. I have found many sites with conflicting information, such as whether or not lemon or lime is alkalizing to the body. Is there a research source of the alkalizing versus acid effect of food that you can recommend? (I have severe gout and my initial PH tests were off the charts on the acid side, and I need to compensate by adding more alkaline sources until I can restore the balance, but I can't seem to find two sources of information in agreement.
A: Fruits and vegetables tend to increase pH (i.e. alkaline), whereas grains, starches and protein tend to decrease pH (i.e. acid). You need a balance. The Zone Diet provides such a balance. I would recommend removing all grains and starches from your diet and adding more vegetables.
