Common food additive may impact gut bacteria, increase anxiety

The impact of emulsifiers
The scientists showed that the emulsifiers did impact gut bacteria, but in different ways for male and female mice. They also showed that the changes in behavior were different between the sexes.

Specifically, they saw an increase in anxious behavior, particularly in male mice. In female mice, there was a reduction in social behavior.

Exactly how emulsifiers might affect behavior is not known, but there are some theories.

"[W]e know that inflammation triggers local immune cells to produce signaling molecules that can affect tissues in other places, including the brain. The gut also contains branches of the vagus nerve, which forms a direct information pathway to the brain."

Prof. Geert de Vries
Why there should be sex differences is harder to explain. However, scientists know that there are certain differences between the way male and female immune systems work, so this might offer clues.

The group plan to continue this line of investigation. Switching from the mouse model into larger animals will be a necessary move, as the authors write, "determining the extent to which studies in mice are relevant to humans is inherently difficult," particularly in behavioral disorders.
