A December 2022 study by Penn State said, 

“Research has shown that people who have a lot of different microbes have better health, and a better diet, than those who don’t have much bacterial diversity,”

“It’s such a simple thing that people can do,” 

“The average American diet is far from ideal, so I think everyone could benefit by adding herbs and spices. It’s also a way of decreasing sodium in your diet but flavoring foods in a way that makes them palatable and, in fact, delicious! Taste is really a top criterion for why people choose the foods they do.”

“We need a lot more research on the microbiome to see what its proper place is in terms of overall health.”
