The Mind-Gut Connection by Emeran Mayer, MD

Combining cutting-edge neuroscience with the latest discoveries on the human microbiome, a practical guide in the tradition of Wheat Belly and Grain Brain that conclusively demonstrates the inextricable, biological link between mind and body.

We have all experienced the connection between our mind and our gut—the decision we made because it “felt right;” the butterflies in our stomach before a big meeting; the anxious stomach rumbling when we’re stressed out. While the dialogue between the gut and the brain has been recognized by ancient healing traditions, including Aryuvedic and Chinese medicine, Western medicine has failed to appreciate the complexity of how the brain, gut, and more recently, the microbiome—the microorganisms that live inside us—communicate with one another. In The Mind-Gut Connection, Dr. Emeran Mayer, Executive Director of the UCLA Center for Neurobiology of Stress, offers a revolutionary look at this developing science, teaching us how to harness the power of the mind-gut connection to take charge of our health.

The Mind-Gut Connection shows how to keep the brain-gut communication clear and balanced to:

• Heal the gut by focusing on a plant-based diet
• Balance the microbiome by consuming fermented foods and probiotics, fasting, and cutting out sugar and processed foods
• Promote weight loss by detoxifying and creating a healthy digestion and maximum nutrient absorption
• Boost immunity and prevent the onset of neurological diseases such as Parkinson’s and Alzheimer’s
• Generate a happier mindset and reduce fatigue, moodiness, anxiety, and depression
• Prevent and heal GI disorders such as leaky gut syndrome; food sensitivities and allergies; and IBS; as well as digestive discomfort such as heartburn and bloating
• And much more.

The Reason

I want to read more nonfiction and I got curious about the gut and gut-health.

The Quotes

“The immune cells residing in your gut make up the largest component of your body’s immune system; in other words, there are more immune cells living in the wall of your gut than circulating in the blood or residing in your bone marrow.”

“The gut is also the largest storage facility for serotonin in our body. Ninety-five percent of the body’s serotonin is stored in these warehouses.”

“Your gut microbes are in a prime position to influence your emotions, by generating and modulating signals the gut sends back to the brain.”

“Adults often think that self-confidence is something a child learns, but little kids are by their nature always invincible, it’s self-doubt that needs to be taught.”

My Thoughts

This book was incredibly informative and I learned a lot, but I did feel it was a little dry. Some of the most recent nonfiction books I’ve read have been written by very entertaining and accomplished writers, so I might be a little unfair in my judgement. This book is well-written and very interesting, jam-packed with a lot of details about the gut microbiome, its history, research, and effects on our health.

I was most fascinated with the chapter about gut feelings, and how our microbiome really does affect our intuition because it acts as our second brain and sends signals to our brain when it recognizes a feeling it has had before. I am obviously not explaining it very well, but I do recommend reading this book yourself for this chapter and to understand your body and how it works, especially since we’ve got more bacteria in our gut than we have cells in our body.

Personally, I’ll admit that while I enjoyed reading this book in the moment, I didn’t end up retaining much of the details, as is normal for me as a reader. However, it’s piqued my interest enough that I know I’d like to read more about the gut as well as do more to ensure my own gut health. I’m also intending to reread this book at some point, after I read some others that are more accessible and entertaining to the layperson. I’m hoping I’ll retain more by then and come back to this book with a better understanding.
