Exercise changes gut bacteria and may prevent bowel cancer

Exercise changes gut bacteria in just six weeks, new research reveals.

Previously inactive people who exercise for at least 30 minutes a day three times a week experience increased levels of gut bacteria that produce butyrate, a study found.

Butyrate is an anti-inflammatory acid that has been linked to protection against bowel cancer, as well as weight loss and stronger immunity.

The same findings were previously found in mice, who became less likely to develop the inflammatory bowel disease ulcerative colitis if they were active.

Lead author Professor Jeffrey Woods from the University of Illinois, said: 'These are the first studies to show that exercise can have an effect on your gut independent of diet or other factors.'

Yet, the catch is exercise's positive impact on gut bacteria is reversed if people revert to being inactive.
