Gut Study Divides People Into Three Types
from Nature News
Just as there are a few major blood types that divide up the world,
so too, a study has found, there are just three types of gut-microbe
populations. The result could help to pinpoint the causes of obesity and
inflammatory bowel disease, and to personalize medicine.
"This is important. Say you want to compare ill people and healthy
people; you better match them properly [by gut type]," Dusko Ehrlich
told Nature at a human microbiome conference in Vancouver,
Canada, in March. Ehrlich, a senior researcher on the paper published in
Nature, is director of the Microbial Genetics Research Unit at
the National Institute for Agricultural Research in Jouy-en-Josas,
France, and part of a European consortium aiming to unpick links between
gut microbes and disease.
The finding of just three types of gut-microbe population was an
unexpected result that fell out of the team's early analysis. The types
aren't related to age, gender, nationality or diet. "What causes it? We
don't know," says Ehrlich.
