New Research Suggests That Your Gut Bacteria Could Impact Your Decision-Making

The intestinal microbiota significantly impacts mental and social health, influencing cognition, stress, and social interactions as evidenced by animal studies and emerging human research. Hilke Plassmann and colleagues found that dietary supplements affecting the gut microbiota can alter human decision-making in social contexts like fairness in the ultimatum game, suggesting potential pathways for future therapeutic exploration.

While these findings are promising, most of this research is carried out on animals and cannot be extrapolated to humans. Nor does it allow us to understand what neuronal, immune, or hormonal mechanisms are at work in this fascinating dialogue between brain and intestine: researchers observe a link between the composition of the microbiota and social skills but do not know precisely how one controls the other.

To fully exploit this effect, the researchers recruited 101 participants. For seven weeks, 51 took dietary supplements containing probiotics and prebiotics , while 50 others received a placebo. They all participated in an ultimatum game during two sessions at the beginning and end of the supplementation period.
