Office Hours: The Truth About Environmental Toxins (And How to Protect Yourself)
3/2/202631 min
Most of us think chronic disease is just about food, genetics, or aging. But there’s another major driver most doctors never talk about: your total toxic load. Every day, we’re exposed to chemicals in our food, water, air, and everyday products. Over time, that burden can disrupt hormones, damage mitochondria, drive inflammation, and overwhelm your body’s natural detox systems. This episode isn’t about fear—it’s about clarity. Because your body already knows how to detox. You just have to lower the load and support the system. In today’s Office Hours, I break down: • How environmental toxins disrupt hormones, metabolism, brain function, and immunity • The biggest everyday sources of exposure—and the highest-impact swaps you can make • How to support your body’s built-in detox pathways through food, fiber, hydration, and sweating • Simple, realistic steps to lower your toxic load without extreme cleanses or perfection This isn’t about living toxin-free. It’s about living toxin-smart. Visit https://www.functionhealth.com/ for 160+ lab tests at just $365 a year.
