A new Tulane University study suggests the Mediterranean diet’s brain-boosting benefits may work by changing the balance of bacteria in the gut.

In a study published in Gut Microbes Reports, researchers at Tulane University School of Medicine found that subjects following a Mediterranean diet developed distinctly different gut bacteria patterns compared to those eating a typical Western diet.
