ABSTRACT Some characteristics of dietary fiber that may contribute to the epidemiology of intestinal disease including colon cancer were investigated. Soft white wheat bran (AACC), hard red wheat bran (AACC), corn bran, and cellulose were tested for their ion exchange capacity and ability to bind mutagens (benzopyrene, 2‐amino anthracene (2‐AA), and mutagens extracted from fried ground beef. The wheat brans had the highest ion exchange capacity and were effective in binding the 2‐AA. Benzopyrene and the fried ground beef mutagens were not effectively bound by fibers. The results suggest that dietary fibers may modify the levels of some intestinal mutagens, but may be ineffective for fried ground beef mutagens.
