Hi I've mine since January . I was told the same but over last few wks ive tried different things out to see what happens. I had complications with mine and ended up in hospital for 3 months it stopped working. I can't have dairy or gluten since I had op. Onions ran straight through me. I eat apples, peaches without skin no problem. Tried lettuce last wk and had no problems. I also use lomotil which helps me big time. I don't have to empty bag half as much anymore.
