The Gut-Brain Connection: How a Healthy Gut Fuels a Healthier Mind | Sheila Meyer


Why Gut Health is More Than Just Digestion
When we think about staying healthy, we usually focus on eating right, exercising, and getting enough sleep. But there's another powerhouse in your body that's quietly influencing almost everything — your gut.

This isn’t just about digestion. Your gut is home to trillions of microbes, collectively known as the gut microbiome, which do everything from helping you absorb nutrients to producing hormones that affect your mood. And most importantly, your gut has a direct line to your brain.
This mind-body connection is called the gut-brain axis, and it's revolutionizing how we understand wellness.

What Is the Gut-Brain Axis?
Think of your gut as your second brain. It even has its own nervous system — the enteric nervous system — with over 100 million nerve cells. It communicates with your real brain through the vagus nerve, a sort of biological information superhighway.

This communication affects:
  • Mood and mental clarity
  • Stress levels
  • Sleep quality
  • Pain perception
  • Immune response
When your gut is healthy, your brain usually is, too. But if things are off in your digestive system, you may find yourself feeling foggy, anxious, or down — even if you’re eating well and exercising regularly.

How an Unhealthy Gut Affects the Brain
A balanced gut supports mental clarity, good mood, and energy. When your gut microbiome is imbalanced (a condition called dysbiosis), your brain can feel the effects. Here’s how:
  • Mood Disorders & Brain Fog: Your gut helps produce neurotransmitters like serotonin (the “happy hormone”) and dopamine. In fact, about 90% of serotonin is made in the gut. When your gut is struggling, your emotional health often takes a hit — leading to anxiety, depression, or difficulty focusing.
  • Chronic Inflammation: Around 70% of your immune system lives in your gut. If your gut barrier is compromised (commonly referred to as “leaky gut”), it can trigger widespread inflammation. Inflammation is now recognized as a contributor to conditions like depression, brain fog, and even neurodegenerative diseases.
Stress and the Vagus Nerve
Chronic stress weakens the gut-brain connection by disrupting the vagus nerve. This can slow digestion, weaken immunity, and lead to a cycle of poor gut and mental health. Ever had a “gut feeling” or butterflies in your stomach before a big event? That’s the gut-brain axis in action.

Signs Your Gut Might Be Out of Balance
According to clinical nutritionist Lori Fish Bard, MS, HHC, gut dysfunction often shows up in surprising ways. You don’t always need digestive issues to have a problem.

Common signs of an imbalanced gut include:
  • Brain fog or mental fatigue
  • Unexplained headaches
  • Skin conditions (acne, eczema, rashes)
  • Joint pain
  • Mood swings or anxiety
  • Weakened immunity
  • Sleep issues
If any of these are frequent in your life, your gut could be sending a distress signal.

5 Ways to Naturally Improve Gut and Brain Health
You don’t need a gut reset detox or a shelf full of supplements. Supporting your gut-brain connection is simple with a few lifestyle changes.

> Eat for Your Microbiome
  • Probiotics: Found in yogurt, kefir, sauerkraut, and kimchi — these good bacteria help keep your microbiome diverse.
  • Prebiotics: Found in foods like garlic, onions, leeks, and bananas — these are the “food” for your probiotics.
TipStudies show that essential oils like oregano, peppermint, and thyme may also help balance gut bacteria when used appropriately.

> Exercise Regularly
Movement doesn’t just help your heart — it supports your gut, too. It boosts microbial diversity and supports brain health.
  • Aim for at least 30 minutes of moderate activity most days.
  • Include strength training at least 2x a week for long-term vitality.
> Manage Your Stress
Your brain and gut are always talking — and stress makes that conversation chaotic.
Ways to calm your system:
  • Deep breathing or meditation
  • Yoga or tai chi
  • Journaling or mindful walks
  • Reducing screen time and social media noise
> Prioritize Sleep
Poor sleep affects both gut bacteria and your brain’s ability to reset. Aim for 7–9 hours of restful sleep each night.

> Stay Hydrated
Water helps everything from digestion to detoxification. Add lemon or cucumber for extra flavor and gut-friendly antioxidants.

Your Gut is Your Wellness Gateway
Modern science is finally catching up to what many traditional health systems have long known — health truly starts in the gut. A well-balanced microbiome supports not only your digestion but your mental clarity, emotional stability, and immune resilience.
By nurturing your gut with better food, movement, stress reduction, and sleep, you're also supporting a happier, healthier brain.
So next time you’re feeling off — whether it’s your mood, skin, or focus — check in with your gut. It might just hold the answers you’re looking for.

My Freedom Journey

 
People, including doctors, thought we were crazy...all in our heads.  After all, how could normal, every day household and personal product smells affect your ability to function, to cause you to be incoherent and feel shaky inside, to have an emotional break-down?  Inside we were dying.  Outside we appeared normal. 
Fragrances were, and are, part of every day, normal life.....candles, laundry, cleaning, perfumes.  Everyone and their neighbor used them.  For us, we either had to isolate ourselves or suffer the following day or two with a toxic hangover.  Isolation is never a good option, especially with children.  During the summer it was impossible to go outside without inhaling someone's laundry or the recent lawn product application.  My husband was so bad one summer that he could eat constantly and, yet, still lose weight.  Every month I would get a sinus infection and/or chest congestion. 
Then came the food sensitivities and autoimmune disorders.  How could food cause my ears to be red and hot, my cheeks to flush, and cause my entire body to break out multiple times in a horrendous, red, itchy, inflamed rash only to burn when scratched and ooze yellow, sticky fluid?  Imagine, every day having gauze pads over the majority of your body under your clothes and hoping the rash doesn't drain so much that it soaks through your clothes.  It would take months to disappear.  People said "just get a cortisone/steroid shot" for relief.  They could not understand why that was not my choice
By discovering and eliminating my many triggers, finding a new, non-toxic way to support my immune system, my liver, and my thyroid, I have not had a major skin breakout for about 3 yrs and have been able to manage my autoimmune disorders without the use of standard medication. 
I finally found a way to acquire "Freedom from Toxins", "Freedom to Achieve Wellness", and "Freedom to Choose".
