"There's no magic elixir for healthy aging, but here's one more thing to add to the list: good gut health."

"A study published in the latest issue of Nature finds diet may be key to promoting diverse communities of beneficial bacteria in the guts of older people."

"To evaluate this, researchers analyzed the microbiota, or gut bacteria, of 178 older folks, mostly in their 70s and 80s."

"Some of the people were living in their own homes, and their diets were rich in fiber, fruits, vegetables, grains, poultry and fish."
