Study: Gut bacteria linked to stress and depression, diet may help mental health

Science is slowly unraveling the mysterious link between the microbiome — the bacteria and other microorganisms in our guts and bodily tissues — and our state of mind.

One study found that adding probiotics into the diet reduced stress in volunteers. Another points to a link between gut bacteria and depression. Researchers say the findings add to growing evidence that the gut and brain are closely connected. While the exact mechanisms are still being studied, the message for now is simple: a healthy gut may support a healthier mind.

Overall, experts suggest keeping gut microbes happy with a varied, plant-rich diet complemented with fermented foods as another way to aid mental wellbeing.
