The brain is no exception. As research is revealing, our microbes— especially those living in the gut— have a powerful effect on the brain, influencing our emotions, our thoughts and even our memory. And when those microbes are disturbed, so too are our physical and mental health. For example, researchers have now linked obesity, anxiety, depression, autism, eating disorders and more to the gut and its flora.
Neuroscientist Christopher Lowry discusses the emerging science that's connecting the microbiome —the community of microbes that inhabit the body—with brain health, including whether we can treat common brain disorders through the gut.
