Got Food Cravings? What’s Living in Your Gut May Be Responsible
22nd April 2022
Eggs or yogurt, veggies or potato chips? We make decisions about what to eat every day, but those choices may not be fully our own. New University of Pittsburgh research on mice shows for the first time that the microbes in animals’ guts influence what they choose to eat, making substances that prompt cravings for different kinds of foods.
“We all have those urges — like if you ever you just feel like you need to eat a salad or you really need to eat meat,” said Kevin Kohl, an assistant professor in the Department of Biology in the Kenneth P. Dietrich School of Arts and Sciences. “Our work shows that animals with different compositions of gut microbes choose different kinds of diets.”
