Subjects

In a recent edition of Molecular Psychiatry, Berding et al. concluded from the results of an intervention study that using a microbiota targeted diet or a psychobiotic diet to positively modulate gut-brain communication holds possibilities for the reduction of perceived stress [1]. The psychobiotic diet resulted in a reduction of perceived stress of 32% compared with 17% for a normal diet. The authors suggested a role of microbiota in modulating perceived stress.

Berding et al. reported correctly that, although improvements in stress responses were only observed within the intervention group, there were no significant differences between groups after the intervention.
