If you google alkaline-forming foods, there are a gang of sites to choose from. Alergies are no joke. However, we tend to use the term loosely. In your case it seems to be the change in the PH level of your body. "Normal" is from 6 to 6.8 or so. I don't envy people who have to watch what they eat. Also, there are sites that explain the problem better'n I ever could.
