The impact of your microflora on your brain function has again been confirmed by UCLA researchers who, in a proof-of-concept study, found that probiotics (beneficial bacteria) indeed altered the brain function in the participants.

As reported by UCLA:1

“Researchers have known that the brain sends signals to your gut, which is why stress and other emotions can contribute to gastrointestinal symptoms. This study shows what has been suspected but until now had been proved only in animal studies: that signals travel the opposite way as well.

The study, published in the peer-reviewed journal Gastroenterology,2 claims the discovery “carries significant implications for future research that could point the way toward dietary or drug interventions to improve brain function.” Naturally, I urge you to embrace dietary changes here, opposed to waiting for some “miracle drug” to do the work for you…
