Hey all, just found this forum. Is it possible for bran, in particular miller bran to cause constipation? I have tried to incorporate it in my diet and I have never been so constipated and now my stool is very light colored, like almost white. I am currently undergoing a series of 12 colon irregations that have seemd to pass a lot of sludgy stuff. But i am really concerned with my light colored stool, constipation and increased appetite.
