Scientists at Wake Forest Baptist Medical Center found that eating a plant-based diet enhanced the good bacteria living in the gut by up to 7 percent as compared to only 0.5 percent from eating a more meat-centric, Western diet.

Drinking alcohol may change the bacteria in your mouth. A new study suggests that regular, heavy drinking can change the very microbiome (i.e., the collection of various microorganisms that reside in the body) of your mouth—and not in a good way.
