The research, carried out by Dr Javier Bravo, and Professor John Cryan at the Alimentary Pharmabiotic Centre in University College Cork, along with collaborators from the Brain-Body Institute at McMaster University in Canada, demonstrated that mice fed with Lactobacillus rhamnosus JB-1 showed significantly fewer stress, anxiety and depression-related behaviours than those fed with just broth. Moreover, ingestion of the bacteria resulted in significantly lower levels of the stress-induced hormone, corticosterone. "This study identifies potential brain targets and a pathway through which certain gut organisms can alte
DID YOU KNOW… that lack of beneficial gut bacteria can impact behavior? In a published study, it was found that mice that lacked beneficial bacteria in their gut showed different behavior compared to normal mice. This altered behavior was accompanied by neurochemical changes in the brains of the lab mice.
