Looks like Harvard University scientists have given us another reason to walk past the cheese platter at holiday parties and reach for the carrot sticks instead: Your gut bacteria will thank you.
Switching to a diet packed with meat and cheese — and very few carbohydrates — alters the trillions of microbes living in the gut, scientists report Wednesday in the journal Nature.
The change happens quickly. Within two days, the types of microbes thriving in the gut shuffle around. And there are signs that some of these shifts might not be so good for your gut: One type of bacterium that flourishes under the meat-rich diet has been linked to inflammation and intestinal diseases in mice.
"I mean, I love meat," says microbiologist Lawrence David, who contributed to the study and is now at Duke University.
"But I will say that I definitely feel a lot more guilty ordering a hamburger ... since doing this work," he says.
