In 2025 it seems like there are two types of people—those who are insanely diligent about health, the people who learn everything there is to know about ingredients, the people who run every beauty or cleaning product through the EWG Working Group (a database where you can check for the presence of alleged toxins in household ingredients)—And then there are the rest of us. The people who go about their daily lives trying to do the best they can when it comes to health.

The problem is—as hard as most try—the world around us is laden with processed foods and chemicals. Their exact impact on the body is under intense debate. But there’s no question that America is facing a crisis of chronic illness. You don’t have to be a scientist or a doctor to see that.

There are countless experts out there—and we’re using the term “expert” loosely—with advice about what you should or shouldn’t eat. This advice, however, is often geared toward people who have more time and resources. So today we have someone who can thread the needle and give practical health advice.

Dr. Mark Hyman is one of America’s most famous doctors. He’s written 15 books, and he hosts a hit podcast called The Dr. Hyman Show. He is also an entrepreneur—and his new company, Function Health, is focused on empowering people to understand what is going on in their bodies, through lab testing.

Hyman’s fundamental insight is that rather than treating the sickness, which is the way Western medicine has typically been practiced, we should look at the root cause and focus on preventative care. To do that, he says we need to go upstream, to look at the way our food is farmed, processed, and how we approach the grocery store. He calls it functional medicine.

Today on Honestly, Bari asks him how we got so sick and how to eat better. She asks about sleep, stress management, environmental toxins, community, and loneliness. And if the solution is at the individualized level or at the policy level—and if policy change is even possible. And most importantly, she asks how we can all live better.
