Stress impacts our gut bugs

A new study from Nature Scientific Reports indicates that stress may be as unhealthy to our gut microbiota as a bad diet. The study was carried out on animals but may have implications for humans. The researchers set out to evaluate the factors that impact on the gut microbiota and found that female mice exposed to stress showed significant changes to their microbiota: the changes in the composition of gut bugs looked like they had been eating a high fat diet.

While we often think that stress has a mostly psychological effect, this study highlights the physical impacts.
