yes, it groups food by category (eg. fruits, vegetables, etc) and then sorts them in order of low, moderate, high and very high chemicals. then next to each food is a code s (salicylate), g (glutamate) or a (amine). if you scroll down the link, it has an eg of the fruits list on there. i tried to find the charts i used to use from the net but they have pulled them down for copyright reasons sorry!
