The Pit In Your Stomach is Actually Your Second Brain

Decades ago, when every one of the ten thousand doctors I saw (ok, so I exaggerate  . . a bit) pronounced me “fit as a fiddle” despite the crushing pain, depression and fatigue I was experiencing. I decided the only explanation was my body was inhabited by alien creatures.  Turns out my diagnosis may have been close to the truth.

“As researchers turn their microscopes to these hidden environments, they have discovered something remarkable: There’s an entire ecosystem of bacteria and a vast neural network operating in our guts. This ecosystem is our second brain, and comprises some 100 million neurons, more than the spinal cord. This is not a thinking brain—it does not reason, write poetry, or solve multi-linear regressions—but mounting evidence suggests that your gut’s health strongly influences your mood.”

“The enteric nervous system is a mesh-like network of neurons that lines the entire digestive track. It causes the sensation of nervous butterflies or a pit in your stomach that are innate parts of our psychological stress responses. Up to 90 percent of the cells involved in these responses carry information to the brain rather than receiving messages from it, making your gut as influential to your mood as your head is. Maybe even more.”

Even crazier is that our second brain is actually only half of us. Inside the digestive system, the enteric nervous system mainly communicates with bacteria. These are completely separate creatures that make up our microbiome, and there are just as many of them inside of us as our own human cells.

“Our gut bacteria have evolved with us since birth. They help digest our food and fight off unfriendly outsiders like viruses and molds. To keep us healthy they need to be healthy and plentiful as well. When they’re not, we feel it: This biomass of bacteria communicates with important neurotransmitters embedded throughout our enteric nervous system to send messages that influence the way we feel.”

“This could herald good news for those who suffer from anxiety or depression. Studies indicate that those with healthy and diverse gut microbes are less likely to suffer from either malady. And many of us who grew up in too—clean environments, frequently took antibiotics, and ate junk food have a decidedly unhealthy microbiome. So changing one’s diet could well benefit far more than your waistline.”

“If you’ve seen the term “probiotics” recently, this is why. Probiotics are foods that nourish and promote your biome. They’re foods cultured with the strains of healthy bacteria. Yogurt is a cultured food. Unfortunately, many grocery store yogurts are little more than a thickened, sweetened milk product. But yogurt that lists strains such as Lactobacillus acidophilus and Bifidobacterium lactis actually contain the healthy bacteria your gut needs. “Prebiotic” foods, meanwhile, support a healthy gut ecosystem in which your bacteria can thrive. Together, prebiotic and probiotic food help keep your second brain full of the vibrant bacterial community it needs to function.”

Some gut-healthy foods – yogurt, sauerkraut & dark chocolate

“How exactly these gut-healthy foods help manage depression is not yet totally clear. The science on the gut-brain connection is still young, especially as it relates to our mood. But studies continue to find promising correlations. There is evidence that a healthy gut can curb inflammation and cortisol levels, lower your reaction to stress, improve memory, and even reduce neuroticism and social anxiety.”
