Happy Thanksgiving from the American Museum of Natural History!
This year, we’re thankful for our microbiome, which is particularly helpful in digesting the traditional holiday feast many of us will be enjoying today. Your digestive tract is home to around 100 trillion bacteria—more than all the stars in the Milky Way galaxy. Many fibers from food, including cellulose, cannot be digested by the human body alone—but resident bacteria produce enzymes that can break them down.
