Diet induced changes in our gut flora influence behavior. Prebiotics and Probiotics have beneficial effects on stress related behaviors such as anxiety and depression.

Our gut microbiome is made up of an enormous number of microorganisms. These microorganisms are an important factor to healthy metabolism and there is evidence linking gut microbiota and metabolic disorders such as obesity and diabetes. In the past few years, neuroscience research has demonstrated the importance of our gut in the develdopment of brain systems that are related to both stress reactivity and stress-related  behaviors.
