I don't know why they would cause C for me. But, as Heather says, sometimes too much IF can cause C...it causes the spasms and that locks up your intestines. I don't know why nuts are such a problem for me. I wish they weren't. But I can't even handle natural peanut butter. The day after eating it I feel AWFUL. Nuts and nut butters give me horrible spasms...which leads to the C. Maybe my stomach just can't handle that kind of IF. But if they work for you that's great.
