A brisk walk for 20 minutes a day may not sound like much, but it could make a big difference for colorectal cancer patients. Regular physical activity reduces inflammation by improving the gut microbiome of patients, including patients who are obese, scientists at Huntsman Cancer Institute found. They researched the impact of exercise on the gut microbiome, the trillions of bacteria that live in our digestive system. Investigators found moderate exercise improved outcomes in colorectal cancer, the third most common cancer in the United States, excluding skin cancers. Scientists explain why their findings are so significant.

James McKinlay is an associate professor of biology at Indiana University. His group used genetics, analytical chemistry, and computational modeling to identify factors that determine hydrogen gas production levels. More broadly, we identified factors that govern cooperative relationships between microbes.
