Have you ever gotten “butterflies in your stomach” when you’re nervous or excited? Or maybe you’ve had a go-with-your-gut moment, when you absolutely KNEW something was true?
Well, science backs up that these feelings could actually be coming from your “secret brain” inside your gut, called your enteric nervous system! It’s made up of layers of cells (more than 100 million of them) that line your gastrointestinal tract, all the way from your esophagus to your rectum.
And what you eat can have a BIG impact on this entire system, and so can stress.
Your “secret brain” communicates directly back-and-forth with the brain in your head through the “gut-brain axis.” This axis is an incredibly complex system involving hormones, nerves, body fluids, your immune system and more.
And here’s where it gets interesting …
90% of the communication goes from your gut TO YOUR brain, and only 10% from your brain to your gut. Researchers are looking into how imbalances or irritations in your gut lining and microbiome affect not only your brain, but your overall health. Your gut has around 100 trillion bacteria – and there are more than 1,000 known strains. But only a handful or two of those strains make up most of the population of a healthy gut.
When these bacteria get out of balance (due to poor diet, some medications including antibiotics, stress, toxins, and more), it can throw more than just your gut out of whack. It can make you MOODY!
That’s because your gut produces neurotransmitters like serotonin and dopamine, which have a huge impact on your mood. And way more important than mood …
There are known links between gut issues and autism, as well as anxiety and depression, but scientists are looking into so much more.
Another example – irritable bowel syndrome (IBS) is super common, with as many 45 million sufferers in the U.S. alone! IBS is actually considered a gut-brain disorder, because not only does it affect your gastrointestinal tract, it’s associated with depression, anxiety, and imbalances in the gut microbiome.
So … what can you do to keep your “secret brain” system happy? Live a gut-friendly lifestyle!
- Cut back on (or eliminate!) sugar and processed foods
- Eat fiber and probiotic-rich/fermented foods
- Destress!
- Get regular exercise
- Get 7-8 hours of sleep at night
And if you have serious or chronic gut issues, definitely check in with your doctor. If you’re even THINKING about making some changes in your life, wouldn’t that be worth at least a conversation?

Thanks for sharing this I didn’t know there’s a lot going on in our gut. This is such a great read.
You definitely feel the difference mentally when your mind and body are in tune! Great, important tips for improving the mood, especially during these uncertain times when everyone is feeling stressed!
This explains so much! I’ve always heard personal trainers talk about the importance of gut health and sometimes it all goes right over my head, but it also makes sense that our ‘ gut feelings’ are so powerful. It’s where we feel that fight/flight feeling as well as excitement. And I totally need to read more on our ‘Secret Brain”!
Interesting read! I always felt this was true so I am happy to read about this. Thanks for these tips for changing and improving moods.
It is good to consider different things when it comes to mental and physical health. These are nice points to think about.
I have studied biology and know about how the nervous system works and it is surprising the symptoms that can be caused from things you would think are not connected in the slightest. The body really is very clever!
This has been such an informative post, I was not aware of my second brain and how my diet and way of life affects my mood and well being.
This is absolutely brilliant! I always felt there was a correlation, as I’m sure many of us did, but to see it backed up is so good to know!
Oh wow! I literally never thought of it this way! Now I know that an exercise actually keeps the gut happy and thus any. mental distress away!
Thanks for this informative post!
One thing that affects my mood terribly are artificial hormones. I had to go through a series of hormonal treatments and it was pretty terrible for me.
