According to scientists from Babraham Institute, different diets alter the bacterial composition of the intestine. This, in turn, affects the genes and the risk of developing colorectal cancer increases. The scientists have carried out experiments in mice and cell cultures. According to Medical News Today the researchers were interested in what role the short-chain fatty acids play in disease prevention.
