“ Wheat bran may be properly called an intestinal broom or cleansing agent.Man, in the process of preparing his food, has invented expensive and complicated machinery for removing all cellulose and roughness from his diet. He has suffered both stomach and intestinal congestion just to the extent that this refining process has been carried on. Bran puts back into the diet not only what modern milling methods have taken out of it, but that which civilized habits of refining have eliminated from our food. ”
