The community of microorganisms that live inside of your stomach is one of the most important markers of health, physically and psychologically.
Part of the rise in autism is due to better diagnosis, but Dr. Emeran Mayer thinks it's something in our environment, and within us, that has played a role in causing this increase.
The genetic risk for autism has always existed, but in the last 40 years the prevalence has risen dramatically – and not in any one location, but across all developed nations. Many researchers are looking to identify the trigger and, as a gastroenterologist and neurologist, Dr. Emeran Mayer is following the trail of evidence that points to the microbial composition of the digestive system and its relationship to the brain. The gut microbes of those with autism differs from people who aren’t on the autism spectrum, but so far many of the studies have not been sufficient to draw solid results. Dr. Mayer runs through one of the more compelling studies and explains how a yet unapproved strain of probiotic may be the answer to the decreasing the incidence of autism in the future. Dr. Emeran Mayer's most recent book is The Mind-Gut Connection: How the Hidden Conversation Within Our Bodies Impacts Our Mood, Our Choices, and Our Overall Health.

Neuroscientists now think of the gut as a "second brain"; it independently controls your digestive processes and is in constant conversation with your main brain. What do they talk about? Depression, theorizes Dr Emeran Mayer.
We all feel things in our gut – intuitions that give us subtle physiological alerts, stress and anxiety that unsettle us, bad reactions to food, and conversely feelings of contentment from the right food, or flutters from an exciting experience. But according to Dr Emeran Mayer, what we feel is just a small fraction of what’s going on in a region of our body that is still quite mysterious – even to the experts.
