Researchers discover associations among PTSD, diet, and the gut microbiome

Boston, MA—The human gut microbiome has a significant impact on our health. Research has shown that it can influence the development and response of emotions, but the relationship between post-traumatic stress disorder (PTSD) and the gut microbiome has been unexplored.
