Repost: Your Two-Brain Lifestyle: How to Heal Mind, Brain and Gut

This blog post originally appeared in The Huffington Post.

Less might sometimes be more, but two brains are most definitely better than one! How extraordinary then that research continues to confirm a second brain that resides in our guts.

Yes, our gut has its own neural network, the enteric nervous system (ENS). Our ENS doesn’t wax philosophical or make executive decisions like the gray shiny mound in our skulls. Yet, in a miraculously orchestrated symphony of hormones, neurotransmitters, and electrical impulses, both of our “brains” communicate back and forth.

This connection is actually what accounts for those proverbial butterflies in our stomach and has vast implications on our overall health and wellness. Changes in the diversity of the trillions of bacteria that reside in our gut (called the gut microbiota) can impact upon our mental state. And on the flip side, psycho-social factors, including the way we think and feel, have been implicated in gut problems.

Given my personal experience with SIBO, and professional experience with hundreds of women suffering from depression, anxiety, and GI difficulties, I enjoy teaching about how to live what I like to call a “Two-Brain Lifestyle.”

Here are four ways to begin your two-brain lifestyle journey:

 1. Diet:

“Diet is a central issue when it comes to preserving our gastrointestinal health, because by eating and digesting we literally feed our gut microbiota, and thus influence its diversity and composition.” –– Professor Francisco Guarner (University Hospital Valld’Hebron, Barcelona, Spain)

There is more and more research linking diets to both our gut and brain health. Certain diets elicit a healthier bacterial balance. Overall, and generally speaking, a diet rich in whole, unprocessed, unadulterated, and non-genetically modified foods help to maintain a proper pathogenic gut bacteria ratio. More specifically, the following are key recommendations:

A. Probiotic Intake:

Probiotics can be found in foods such as yogurt, or kimchi, and can also be taken in supplement form. Among other benefits, probiotics keep the bacterial ecosystem in our gut healthy, which in turn helps keep us healthy overall.

The positive impact of probiotics on gut flora has been widely studied in the last few years. In a 2013 study in Gastroenterology, 12 of 25 healthy women ate a cup of yogurt twice a day for four weeks. The rest of the women ingested no yogurt. All women had pre and post brain scans while being asked to respond to a series of images depicting different facial expressions. Results indicated that the women who ate yogurt were calmer when shown various emotions than the control group. Showing that the yogurt changed the subjects’ gut microbiota, which also modified their brain chemistry.

This means probiotics are potential game changers when treating anxiety and mood difficulties.

B. Low Sugar/Low Simple Carb Diet:

It is hard to say this, given that a love for chocolate has a special place in many of our lives, but excess sugar upsets the balance in the gut by nurturing more pathogenic bacteria, which leads to increased systemic inflammation. And inflammation is a major player in the inception of chronic disease, including mental health difficulties — no good!

In a recent study, researchers fed a group of mice a diet high in sugar and then tested their mental and physical function. The sugar diet negatively impacted the mice’s gut microbiota, impaired their cognitive flexibility, and ability to efficiently adapt to changing situations. The change in gut bacteria also negatively affected the mice’s long-term and short-term memory.

Basically, sugar makes you forgetful and possibly impairs adaptability, but don’t fret, the chocolate craving can still be met: The darker the chocolate, the less sugar. Also, if you don’t want to cut sugar completely out of your diet, eating less overall can still improve wellness.

 2. Physical Exercise:

Ever feel like vomiting when you are scheduled for a job interview? That is just a crude reflection of how stress negatively impacts many aspects of our gut, but give exercise a try, it’s a well-known stress-buster!

A 2014 study found that rugby players not only have more diverse microbiota, but also a high amount of a particular bacterial species associated with decreased rates of obesity and metabolic diseases. While the study didn’t separate the effects of exercise, stress, and diet, it certainly provides evidence for exercise’s possible beneficial impact on gut microbiota diversity.

3. Therapy:

Our gut microbiota talk to the brain and impact how we think and feel, and, the way we think and feel has a profound impact upon the gut. Therefore, negative thinking styles and certain emotional states can disrupt gut functioning and even lead to dysfunction and disease.

Cognitive Behavioral Therapy (CBT) is a type of therapy geared toward identifying and reframing negative and counterproductive thought patterns. In a 2003 study of patients with IBS, a significant number reported less pain, bloating, and diarrhea after 12 weeks of CBT. Stands to reason that therapy should be part of a thorough treatment plan for chronic gut upset!

 4. Relaxation and Stress-Reduction Exercises: 

Studies have shown that stress puts us at risk for dysbiosis, a shift away from healthy gut diversity. This then strips us of a defense against infectious disease, which can potentially wreak havoc on the Central Nervous System (CNS).

Beyond utilizing exercise, which we already talked about, stress reduction and relaxation techniques, such as meditation, help bring the gut environment back to homeostasis. In a recent study from Harvard University affiliates, forty-eight patients with either IBS or Inflammatory Bowel Disease (IBD) took a 9-week session that included meditation training. The results showed reduced pain, improved symptoms, stress reduction, and a decrease in inflammatory processes.

Go with your gut

Just as the best way to boost our brain is by maintaining impeccable gut health vis-a-vis the content of our diet, so too, it might be impossible to heal a distressed gut without considering the impact of stress and our emotions.

So just remember, you are what you eat, and you are what you think, and there are ways to do both more mindfully.
