One thing stands out to me: >The consumption of insoluble fiber tended to be more effective than soluble fiber intake in reducing the risk of total mortality and mortality due to CVD and cancer. My hunch is that this is an epiphenomenon, and that what's actually happening is: 1. people eating large amounts of soluble fiber are consuming fiber supplements (e.g. psyllium husk); and, 2. people eating large amounts of insouable fiber are eating salads, etc.
