Could your diet reshape your gut? new study says yes

This study looked at how switching from a typical Western diet (low fiber, high fat) to a Mediterranean-like diet (lots of veggies, fruits, whole grains) affects the trillions of tiny organisms living in your gut. 160 healthy adults aged 18 to 60 either followed the new diet for 4 weeks or up to 12 months. Researchers tracked changes in gut bacteria, diet quality, and weight to understand how food shapes our inner ecosystem.
