Let’s talk about your gut—not the six-pack kind (though kudos if you have one)—but the powerhouse of digestion, immunity, and even mood regulation. Turns out, your stomach isn’t just a food processor; it’s a critical player in your overall health, mental clarity, and long-term vitality. Here’s the scoop on why your gut is your second brain and how you can keep it happy.
Your gastrointestinal system does more than digest your meals. It’s a nerve-rich hub, complete with neurotransmitters, enzymes, and about 70% of your immune system. Oh, and it’s home to trillions of bacteria, aka your gut flora, working overtime to keep you healthy.
The Hadza people of Tanzania, one of the world’s last hunter-gatherer communities, have some of the healthiest guts on the planet.
Why? Their high-fiber diet from foraged plants and berries, plus minimal meat consumption, creates a robust microbial diversity (700 species per person vs. about 300 in Californians).
The result: They enjoy strong immunity and are largely free of diseases like colon cancer, diabetes, and inflammation-driven ailments common in industrialized nations.
Ever get a “gut feeling”? That’s your enteric nervous system—a vast network of nerves, second only to the brain, connected by the vagus nerve.
Stress alert: Chronic stress messes with this connection, making your gut overreact (cue stomachaches or worse). Diseases like multiple sclerosis and IBS have been linked to poor gut health.
Fun fact: Your gut and brain communicate using signals similar to fiber optics—high-speed, high-stakes.
Your gut microbes aren’t just digestion experts—they’re mood influencers:
Research links: Gut health disorders like IBS are connected to anxiety, depression, and chronic fatigue.
The mood booster: A healthy gut can directly improve mental health, making you happier and more resilient.

We may not all live a nomadic lifestyle, but we can borrow a page from the Hadza health book:
Eat better: Aim for a high-fiber diet with less red meat. Avoid processed foods like they’re your ex at a party.
Move more: Regular exercise strengthens your gut wall, keeps harmful bacteria out, and supports immune balance.
Tame inflammation: While we can’t avoid industrial pollutants, a healthy diet and regular exercise can reduce their impact.
Think of the Hadza as a glimpse of what humanity could be at its best—strong, resilient, and balanced. While we can’t turn back the clock to a simpler time, we can make choices today that improve our gut health, immunity, and quality of life.

Your gut will thank you—and so will your second brain.
