Researchers fed 20 Zulu Africans 600 grams of meat per day for two weeks and fed 20 African Americans in Pittsburgh a traditional Zulu diet comprised primarily of a corn-based porridge called putu. Comparing stool samples before and after the diet exchange in each case, researchers found dramatic changes in colonic microbiota.
â€œOur results show that the human colonic microbiota is shaped by diet in a very dynamic manner,â€ said Rex Gaskins, PhD, professor of Immunobiology at University of Illinois at Urbana-Champaign. â€œNot only that, we observed alterations in the balance of beneficial and detrimental microbial groups, which may explain, in part, the increase in colorectal cancer risk that is conferred by a Western diet.â€
