<<Disclaimer: Verify this information before applying it to your situation.>> Wow, so many responses! A lot of people suggested that I might have a problem with corn, because of all the fructose derived corn syrup. I did cut out all such products years ago because of worrying about such things. I cut out other suspect foods also, such as soy. Other suggestions were to avoid products with fruit skins. Yeah, I definitely realized I had that problem a couple of years ago. I especially had problems withproducts containing red grapes skins (they contain a lot of acid that can irritate the intestines). I did much better once I stopped those products. I also think I have a problem with acid content. I tolerate apple juice much better, without the added vitamin C. I did get response from some people, who really DO have a fructose intolerance. Wh ile my symptoms don't exactly match, I'm going to cut out major sources of fructose (i.e. fruit products) for now, and see how I do. I (now) realize that there's even fructose in grains and vegetables, so I may have decide to vary those also, but one step at a time. :) Meanwhile, I did schedule a colonoscopy for about a month from now. It's definitely not fun, but since my father had a long history of colitis, I want to make sure there's no such problem, and in case my food avoidance plan doesn't help. Thanks all!
