How could diet affect gut health?

Long-term dietary patterns shape the gut microbiome. Gut microbes produce energy by fermenting microbe-accessible carbohydrates, which are found in most fruits, vegetables, whole grains, nuts, seeds, and beans. Diets rich in these types of foods are associated with high levels of gut microbiome diversity and a lower risk of colorectal cancer. Short-term dietary changes can also change the composition of the gut microbiome, and in some cases, elimination diets are used to reduce the symptoms of certain digestive disorders.
