Scientist say variety of gut bacteria a good thing
WASHINGTON — Scientists report finding roughly 170 types of bacteria in the average person’s gut. And they say that’s a good thing.
A study that catalogs all these bacteria found that people with inflammatory bowel disease had fewer species of the microbes. Many of these germs keep us healthy. There are at least 1,000 different types of bacteria living in people’s intestinal tracts. Scientists found at least 57 that inhabit just about about everyone.
Their study is being published in the journal Nature.
