I know the program is controversial and there is a lot of disagreement. But my background in biology kept me interested because what he says about plant "warfare" and the production of chemicals meant to harm, and thus drive off, the herbivore is very accurate. So I decided to try it. I have cut back on whole grains and replace that with a less fibrous carbohydrate at breakfast. I can eat tomatoes and cucumbers and summer squash and not get diarrhea if I peel them and remove the seeds. Those are a few of the things that have helped.
