notes

I didn’t plan to listen to Dirty Genes. I wasn’t on some deep biohacking mission. I was just scrolling through Audible one afternoon, looking for something that felt... real. Something beyond surface-level wellness tips. The title caught my eye—Dirty Genes—and I clicked. Within minutes, I was pulled in. Dr. Ben Lynch didn’t sound like your typical health expert. His voice was steady, clear, and—most importantly—personal. He didn’t lecture. He explained. He told stories. He made complex science feel like a kitchen-table conversation. The deeper I listened, the more I realized: This wasn’t just another health book. This was a wake-up call for my entire body. So here are 8 lessons that hit home—and might just hit home for you, too.

1. You Are Not a Prisoner of Your Genes: I’d always believed genes were fate—fixed, final, unchangeable. But Dr. Lynch shattered that early in the audiobook. Just because you have a genetic variant doesn’t mean you’re doomed. Genes can be "dirty"—temporarily slowed or overwhelmed by lifestyle and environment—but they can also be cleaned up. This flipped the script for me. Suddenly, my health didn’t feel predetermined. It felt malleable. If I could influence how my genes worked by what I ate, how I moved, how I lived—that gave me power. It gave me hope.

2. Symptoms Are Clues, Not Curses: Instead of treating symptoms as random nuisances, Dr. Lynch teaches you to see them as messages—your body’s way of waving a flag. Fatigue? Maybe your methylation pathways are overworked. Anxiety? It could be COMT acting up. Hearing this reframed everything. I stopped being annoyed at my body and started getting curious. That shift—from frustration to investigation—is something I wish more people experienced.

3. One Person’s Superfood is Another’s Poison: Kale. Green tea. Spinach. All hailed as health heroes. But Dr. Lynch points out that depending on your genes, these foods might actually hurt you. For instance, someone with an MTHFR variant might struggle with too much folic acid—even if it’s in your multivitamin. This hit hard. I’ve always chased the “healthy” label, but this book taught me that personalized health is what actually matters. What fuels one body may clog another. Listening to this through his voice, it didn’t sound restrictive—it sounded freeing.

4. Stress Dirties Your Genes Faster Than Sugar Does: I knew stress was bad. But I didn’t realize it could be worse than junk food when it came to disrupting gene expression. Dr. Lynch broke it down clearly—chronic stress can switch off crucial detox and repair pathways. I took that to heart. It wasn’t just about green smoothies anymore—it was about mindfulness, sleep, boundaries, and breath. Your body can only heal if it’s not constantly bracing for a storm.

5. It’s Not Just What You Eat, But When and How: We hear a lot about what to eat, but Dr. Lynch reminded me that timing and rhythm matter just as much. Skipping meals, erratic eating, eating late at night—all of these can disrupt your genes’ natural rhythms. He explained this in a way that made sense—even without charts or diagrams. Just listening, I felt the urgency to bring back structure and respect to my eating patterns. It’s not about perfection. It’s about alignment.

6. Your Environment Is Speaking to Your DNA Every Day: From the plastic you store leftovers in, to the cleaning spray under your sink, to the air freshener in your car—Dr. Lynch helped me realize that my environment is constantly talking to my genes. And guess what? Your genes listen. Loudly. This wasn’t said to scare me, but to empower me. I can’t control the whole world, but I can control my space. Listening to this audiobook made me rethink what I bring into my home—and what I allow around my body.

7. The Dirty Genes Quiz Changed Everything: Midway through the book, Dr. Lynch offers a self-assessment—the Dirty Genes Quiz. I took it while listening and it was like turning on the lights in a room I didn’t know was dark. Suddenly, patterns made sense. My low energy in the morning. My mood dips. My digestion hiccups. He doesn’t just give you information—he gives you tools. Tools to decode yourself, to respond to your body instead of guessing. The quiz is a game-changer, especially when you hear him explain how to interpret the results in real-time.

8. Small Shifts Can Lead to Big Healing: What struck me most wasn’t the science—it was the simplicity. Dr. Lynch doesn’t throw impossible routines at you. He talks about switching your B vitamin. Drinking filtered water. Taking a walk. Turning off screens at night. It made me realize healing doesn’t always require a giant overhaul. Sometimes, it’s about small, consistent shifts. Listening to his calm voice made those shifts feel doable, even gentle. He made change feel like kindness instead of punishment.
