I have IBS also. Most of the time constipated. Sometimes diarrhea but not often. I do one of two things. I take Milk of Mag and I do Juicing. I have a juicer and mix juices together like carrots, apples, pineapple, parsley, strawberries. The only ones I don't mix together are melons. The enzymes in them work better by themselves. Also, the orange must be pealed. You cannot eat orange peel as the oil in it is toxic to the body. also do not eat apple seeds as they contain cyanide. But everything else, you can use the rind and all. It may give you diarrhea but if you juice and eat other smaller meals more frequently, that will help with the constipation and bloating.
