Research examines new methods for managing digestive health
Date:5/18/2013

's results show changes in gut microbiota that might explain levels of colorectal cancer risk.

"African Americans have the highest colorectal cancer incidence and mortality rates of all racial groups in the U.S. The reasons for this are not yet understood," said Franck Carbonero, postdoctoral research associate at University of Illinois at Urbana-Champaign. "Our findings offer insight into this disparity and pave the way for new research."

During the study, 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.

"Our results show that the human colonic microbiota is shaped by diet in a very dynamic manner," said Rex Gaskins, PhD, professor of Immunobiology at University of Illinois at Urbana-Champaign. "Not 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."

New needleless acupuncture therapy decreases symptoms of indigestion

A study from Texas Tech University, El Paso, and the University of Mississippi, Oxford, holds promising results for diabetic patients suffering from indigestion symptoms like nausea, vomiting, bloating and heartburn. The study tested a new method of therapy using a custom-made wireless device to stimulate acupuncture points with electrical waves on the surface of the skin rather than needles.

"Treatment options for this patient group are severely limited," said Richard McCallum, MD, professor and founding chair of the division of gastroenterology, department of medicine, Texas Tech University Health Sciences Center. "This is a novel approach to symptom relief that over
