Recent research suggests that the bacteria that naturally populate the human gut may play an extensive role not just in a person's physical health, but also in their mental well-being.
One study drew a link between certain groups of bacteria and a higher risk of mental healthconditions, including depression.
Another suggested that our gut bacteria may influence certain brain mechanisms and contribute to anxiety.
Over 50% of studies found positive effects
The studies that the team evaluated chose different types of intervention. Of the 21 studies, 14 used probiotics — or "good" bacteria — as the main agent in their interventions regulating intestinal flora. The remaining seven opted for interventions that did not use probiotics, such as simply adjusting a person's typical diet.
Of the 14 that used probiotic-centered interventions, seven used a single probiotic, two used two kinds of probiotics, and five used three or more different types of probiotics.
The team found that 11 out of the 21 studies (52%) concluded that interventions regulating intestinal flora helped reduce anxiety symptoms.
More specifically, among the studies that used probiotics in their interventions, 36% concluded that the strategy was effective. Among the studies that did not use probiotics, 6 out of 7 suggested that the interventions helped alleviate anxiety.
"It is worth mentioning that the efficiency of supplementation of nonprobiotic preparations is as high as 86%," the authors write in their study paper.
Five of the studies used interventions regulating intestinal flora to supplement traditional anxiety treatments. Among these, only the studies that did not use probiotics led to an improvement of anxiety symptoms.

Anxiety: 11 of 21 studies say regulating gut bacteria may help
A new review evaluating the findings of 21 studies suggests that interventions regulating the intestinal flora could help reduce anxiety symptoms.
