High Fiber Diet

Question: Why does a high fiber diet lower blood pressure? I already know that a high fiber, low sodium, and low fat diet lowers your blood pressure. DUH. What I can't seem to find is the reasons these things are true. I'm writing a paper on blood pressure and I've found so many great sources, but not one of them tells me the actual physiological reasons that this type of diet lowers blood pressure. If anyone could point me to some sources on this I would really appreciate it. Any doctors out there??? : )

Answer: The reason is that fiber diet maintains the normal motility of intestines and forms a layer on the mucosa so that fat and other stuffs are not absorbed in the body; and are expelled out during defecation. This is a strong hypothesis.
