I think it is impossible to overstate the importance of this book, which truly heralds a revolution in how to maintain brain health and treat the disorders that affect it. It presents compelling research drawing the connection between the state of one’s microbiome, which includes all the bacteria and organisms living in your intestines, and the raging epidemic of brain disorders we are seeing, ranging from autism and ADHD to dementia. He shows how every system in the body is interrelated, and treating individual symptoms is a grossly flawed approach.
“We're now recognizing from research at our most well-respected institutions from around the globe that the gut bacteria are wielding this very powerful sword of Damocles. They determine whether we're going to have a healthy brain or not, whether our brain is going to function well or not, and whether our brain is going to become diseased or not," says Dr. Perlmutter.
There is an intimate relationship between diet and the microbiome. Gut bacteria manufacture neurochemicals such as dopamine and serotonin, along with vitamins that are important for brain health. Some 80-85 % of serotonin, the feel-good hormone, is manufactured by bacteria in the gut. These beneficial bacteria also work to prevent leaky gut, which is implicated in most autoimmune diseases and neurological disorders. By following the simple recommendations on how to improve the ecology of the gut, you can dramatically improve your overall health, and brain health in particular.
Dr. David Perlmutter is a practicing, board-certified neurologist and a fellow of the American College of Nutrition (ACN). His articles have been published in peer-reviewed medical journals, and his earlier book, Grain Brain, topped the New York Times bestseller list for over a year. There is an excellent interview with Dr. Perlmutter on Dr. Mercola’s website - http://articles.mercola.com/sites/articles/archive/2015/05/17/gut-bacteria-brain-health.aspx - that goes more deeply into the science and implications of these findings, and I strongly recommend to everyone to take the time to read and listen to it.
