Brain Maker

The Power of Gut Microbes to Heal and Protect Your Brain—for Life
by David Perlmutter, MD | Little, Brown © 2015 · 310 pages

Ready to get your brain right? Start with your gut! In this compelling book, Dr. David Perlmutter walks us through the leading-edge science on how to dial in our microbiome to optimize our brain + overall well-being. In the Note, we explore Big Ideas ranging from the power of probiotics and your second brain to the importnace of focusing on root causes rather than just symptoms along with the 6 keys to feeding your microbes.

We call this complex internal ecology that thrives within us and its genetic fingerprint the microbiome (micro for ‘small’ or ‘microscopic,’ biome referring to a naturally occurring community of flora occupying a large habitat—in this case, the human body).

“New, leading-edge science from the most well-respected institutions around the world is discovering that to an extraordinary degree, brain health and, on the flip side, brain diseases, are dictated by what goes on in the gut. That’s right: what’s taking place in your intestines today is determining your risk for any number of neurological conditions…

The digestive system is intimately connected to what goes on in the brain. And perhaps the most important aspect of the gut that has everything to do with your general wellness and mental health is its internal ecology—the various microorganisms that live within it, especially the bacteria.”

~ David Perlmutter, MD from Brain Maker

David Perlmutter has quickly become one of my favorite teachers.

This is the third Note we’ve created on his books. (Check out Power Up Your Brain + Grain Brain for more goodness.)

As I mentioned in the Grain Brain intro, Perlmutter is the only medical doctor in the U.S. who is both a board certified neurologist and a member of the American College of Nutrition.

In Brain Maker, he focuses his decades of wisdom in both neurology and nutrition on the cutting-edge research that’s revealing the power of our gut microbes to heal and protect our brain.

Perlmutter gives us an introduction to the importance of the trillions (!) of friendly little microbes in our gut and then shares some simple practices we can adopt to optimize—showing us how this new science can help everything from ADHD, asthma and autism to chronic fatigue, mood disorders (including anxiety and depression), skin problems and obesity.

You can grab a copy of the book here. As with his other books, this one is packed with wisdom. I’m excited to share a few of my favorite Big Ideas so let’s jump straight in!
