Many people on this board have the mistaken belief that a particular food directly causes C, but unless low fiber foods replace high fiber foods, it will not cause C. There may be certain compounds (as calcium, some say) that slow the colon muscles, but no food in and of itself will actually "clog" the colon (unless you fail to drink enough water). It's a matter of what you DO eat, not what you don't. So, as long as you meet your fiber requirements (which are different for everyone), no food or foods will give you C.
