Three Brains: How the Heart, Brain, and Gut Influence Mental Health and Identity

Did you know you have three brains? Yes, you read that right! You have three brains – your HEAD brain, your HEART brain, and your GUT brain.

Today, more than ever before, people, young and old, are being diagnosed with brain disorders, such as anxiety, depression, insomnia, learning disorders, and dementia. Learning about the causes and risk factors associated with these conditions will give you a greater understanding of what you can do to help prevent and treat these life-limiting conditions.

The human brain has been studied for centuries and amazing discoveries have been made. Research suggests that you actually have three brains: the heart, the gut, and the head brain. There is an intricate relationship between these three brains that influence mental health and optimal brain function.

“Nutrients from whole foods, exercise, and supplements are effective, non-invasive ways to support the ‘three brains’ interaction and optimize mental health and cognition.” Dr. Karen Jensen, ND

Introduction and Synopsis

The Role of the Three Brains
Although the head, heart, and gut brains work together, they have obvious different physical functions and they also perform different mental and emotional roles.

The head brain analyzes information and applies logic.
The heart brain senses the world through emotion and feelings.
The gut brain is used for understanding our identity and who we are in the world. The gut brain also helps us learn self-preservation by teaching us to follow our instinct – the “gut feeling” we all experience at times.

Set up as follows:

  • Chapter 1 discusses the three brains.
  • Chapter 2 discusses stress and the three brains.
  • Chapters 3 and 4 discuss factors that disrupt three brain health.
  • Chapter 5 discusses using nutrition to achieve optimal brain health.
  • Chapter 6 discusses protecting and supporting brain development in children.
  • Chapter 7 discusses three brain, mood, and mental disorders.
  • Chapter 8 discusses sleep disorders.
  • Chapter 9 discusses memory disorders.
  • Includes the Optimal Use Guide

Did You Know:

  • Variations in the composition of the gut microbiota have been shown to impact health on many levels, not just in the gut but in the brain as well.
  • Probiotics have been shown to support individuals with mental health issues, as well as problems with bowel function.
  • The heart is a much more complex organ, both of perception and cognition than was previously believed. Scientists have discovered that the heart produces oxytocin, which is beneficial for many mental health conditions, reducing stress-induced cortisol levels, and weight loss.
  • Oxytocin has also been found in the intestinal tract, where it improves gut motility and decreases intestinal inflammation. Dr. Jensen.


As a professional book reviewer for multiple authors and publishing companies, I highly recommend this book for more than just a one-time read.   It is well set up, jam-packed with information and is so, very, easy to read. A definite wellness warrior recommended read!

“Women constitute 53 percent of the earth’s population. They perform two-thirds of the world’s work for which they earn 10 percent of the income. They own 1 percent of the property, and they have 100 percent of the children. Given these statistics, women should hold the majority of the political power in the world”  – Helen Caldicott, MD.

We don’t because we are too tired from looking after our families, jobs, and homes.🙷

Surprise Me by Sophie Kinsella

I’ve been a fan of Sophie Kinsella/Madeleine Wickam, since first picking up a copy of The Undomestic Goddess back in early 2005.  I was delighted to receive a review copy of Surprise me, and it did not disappoint.



After being together for ten years, Sylvie and Dan have all the trimmings of a happy life and marriage; they have a comfortable home, fulfilling jobs, beautiful twin girls, and communicate so seamlessly, they finish each other’s sentences. However, a trip to the doctor projects they will live another 68 years together and panic sets in. They never expected “until death do us part” to mean seven decades.

In the name of marriage survival, they quickly concoct a plan to keep their relationship fresh and exciting: they will create little surprises for each other so that their (extended) years together will never become boring. But in their pursuit to execute Project Surprise Me, mishaps arise and secrets are uncovered that start to threaten the very foundation of their unshakable bond. When a scandal from the past is revealed that question some important untold truths, they begin to wonder if they ever really knew each other after all.


This is a well-done novel that starts off with a light, chick-lit tone. Sometimes you just need a book that has a humorous take on life and love. I should have known from the blurb alone that this was going to be the book for me. Sophie, you came through and for that, I thank you! This isn’t your usual light chicklit read – its around 450+ pages but those are page turner pages, I found this to be a speedy read for that reason. This is the type of “guilty pleasure” book that you can read and drop the guilt. I’m surprised at how connected I felt with the characters and still find myself reminiscing about the story and feeling a little sad about having to leave them behind and move on to something else. I really like the premise of Surprise Me–rather than the typical Kinsella premise of a single girl trying to get her life together and in doing so ultimately finds love, we have a married couple worried that their marriage has gone stale.  It does take a while to get into if you’re not used to Kinsella’s tone, but the end result is a lovely message about loyalty, appreciation, partnership [and the consequences of the annoying art of not communicating] within a marriage and embracing the future, challenges and all, instead of stunting your growth by living in the past.

I’m a “quote” person, my fave quote from this novel is “Love is finding one person infinitely fascinating. And so… not an achievement, my dear. Rather, a privilege.”

If you are looking for a break from the unpleasantries that life can bring, this is definitely the read for you.




A broken society

I bet I can guess the first thing you did when you woke up this morning. – you scrolled through notifications on your phone before you stepped out of bed to fix that bed-head.


The internet connects us to hundreds, thousands, even millions of people, and yet we’re more isolated than ever. If it isn’t posted on Facebook, Twitter or Instagram – well then it simply didn’t happen.  If we do capture a memory or a look, then we disappear into the realm of likes and follows. If a post goes un-liked – then we are not good enough and we disappear further into the realm to push those feelings of unworthiness away. Distract. Binge. Escape… We’ve become a society who ignore real friendships in favor of spending time thriving on algorithms created by machines who simply mimic our very own misery-inducing patterns.  

We’ve all experienced it. The day is going great: you got out of work early, someone let you in ahead of them in traffic, and for some reason, your hair is just killin’ it today! Then WHAM. You log onto Facebook and see that an oooold high school friend just got engaged to a Sam Heughan look-a-like. UGH. Suddenly your perfect hair day just got a whole lot less significant. Even when you log off, images of the happy fiancés feeding each other spoonfuls of chocolate moose from their couples cooking class are etched into the back of your brain.

Then comes the inevitable torture of wondering why your own life doesn’t compare to their shiny perfect photos.  We’re all in competition, although we prefer not to realize it.  You ran more miles, or your child can dance better, or that selfie got more Facebook Likes than the average. Well done…. No really – well done!

Our broken society judges people by what they can do for others. Can you save children from a burning building, or remove a tumor, or make a room full of strangers laugh? *wink – You’ve got value right there.

Write an unpublished book, you’re a nobody. Write Eat Pray Love and the world wants to know you. Save a life, you’re a small-town hero, but cure cancer and you’re a legend. Unfortunately, the same rule applies to all talents, even untalented talents: get naked for one person and you may just make them smile, get naked for fifty million people and you might just be a Kardashian – the world loves to hate the Kardashian clan, but we are the ones who put them on the pedestal.

We use Instagram filters to make ourselves look more tanned and Pinterest boards to show everyone that awesome room we’re decorating. Whether it’s subconscious or not, we tend to paint a picture on social media that make our lives look like a more perfect version of reality.

You may hate it, but reality doesn’t care. We’re judged by what we have the ability to do, and the volume of people we can impact or get to LIKE what we ramble about while searching for acceptance. This my dears is today’s reality and If you can’t accept this reality, then the judgment of the world will seem very unfair.

The problem isn’t that life is unfair; it’s your broken idea of fairness.

Can you imagine how insane life would be if it actually was ‘fair’ to everyone? No-one would fall in love with anyone who wasn’t the love of their life, for fear of breaking a heart – or god forbid, wasting years of your life with the wrong person. Relationships would only end when both partners died simultaneously. Rain would only fall on bad people, hell – Donald Trump would actually have good hair!

Most of us get so hung up on how we think the world should work (#shinyFBposts) that we can’t see how it does.  Facing that reality might just be the key to unlocking your understanding of the world, and with it, all of your potential.

Ask yourself this simple question – “Am I the same me in real life as I am online?” Since we curate their own lives and show only the highlight reels, the online self is not the same as a true self. It’s okay to embrace the online world, but we mustn’t forget that likes and shares only go so far. Real validation only exists when we are genuine and imperfect.

If you’re not willing or able to give up social media just yet, consider the following suggestions:

  • Start paying attention to the moments you mindlessly open Instagram or Facebook. Be more mindful of the time you spend habitually browsing.
  • Turn off your social media notifications. Use your first moments in the morning to feel gratitude for waking up to a new day.
  • Put your phone away when you’re sharing a meal with friends or family. I repeat: Put. Your phone. Away. Channel your energy into building real, face-to-face relationships.
  • Remind yourself often that what you see online is not a standard by which you should grade your life. Key to understanding = REMEMBER THAT SOCIAL MEDIA IS NOT REAL LIFE

The time to stop is now – Stop judging everyone based on your own cookie cutter ideas of happiness, stop judging yourself based on other’s cookie-cutter ideas of happiness and what it should look like. Stop searching for acceptance and simply accept yourself and your life as it is,  Stop making excuses EVERY time that friend invites you for a glass of wine because you’re too caught up in scrolling news feeds for validation.

Take a break from Social Media and rediscover the simplicities and out-right atrocities of life – it’s all about balance, you can’t live life in a filtered or cropped version of yourself – the only true way to live life is to LIVE it.  Listen to that Nickelback album that ‘everyone’ hates but secretly jam out to in their cars, eat that damn chocolate cake – without taking a picture of it, put down your god-damned phone and wake up with gratitude for a new day.

Your worth is not measured in likes, comments, notes or followers; but in your ability to love, laugh, connect with real people and to ultimately find joy in your life’s purpose.

Art of Falling by Kathryn Craft
