Interview of Prof John Bienenstock about the Microbiome Gut Brain Axis

Certain probiotics, in particular specific strains of Lactobacilli and Bifidobacteria, may also interact with the mood and/or behaviour of an individual, especially stress and anxiety, as Dr John Bienenstock (McMaster University, Canada) emphasised.

These effects can be explained by the bidirectional communication that is established between the brain and the intestines during digestion.
