New research finds that probiotics can reduce negative thoughts.
Research from the Leiden Institute for Brain and Cognition in The Netherlands has determined that one’s gut bacteria affect negative thinking, which is defined as a spiraling of thinking that takes a person from one negative thought to the next.
The research studied 40 healthy people for four weeks. The group was split into two groups. One group was given a probiotic supplement each day. The other group was given a placebo for the same period. This was a triple-blind study.
After the four weeks, the patients were tested for negative thinking and cognitive reactivity for moods of sadness. The researchers found a significant reduction in negative thinking among the probiotic group. They also had lower cognitive reactions to sadness compared with the placebo group.
