Everywhere you turn, there’s another “miracle cure.” A new supplement, a “doctor-secret” detox, or a high-tech device promising to fix your mitochondria or reboot your microbiome. It all sounds compelling—because it’s designed to. But as I often remind listeners and patients alike: just because something makes sense biochemically doesn’t mean it works in real life.

In this episode of Live Long and Well, I unpack why health misinformation is so common and how we can protect ourselves from it—not by shutting down curiosity, but by pairing it with skepticism. This isn’t about fear or rigidity; it’s about discernment in a world flooded with noise.

When Compelling Theories Fall Apart in Practice

Let’s start with a few real-world examples where health information once seemed promising—but ultimately didn’t hold up to scrutiny.

For decades, eggs were demonized because they contain cholesterol. The theory was straightforward: plaque in arteries is made of cholesterol, so eating cholesterol must cause plaque buildup. But large-scale studies, including randomized controlled trials, eventually showed that dietary cholesterol has little impact on blood cholesterol levels or cardiovascular outcomes for most people. You can read the 2015 American Journal of Clinical Nutrition study that helped reverse this thinking.

Another example: cardiac stents. The logic seems ironclad—if a coronary artery is blocked, opening it with a stent should prevent heart attacks. But when researchers put this to the test in randomized controlled trials like COURAGE and ORBITA, they found that stents offered no additional benefit over optimal medical therapy for patients with stable symptoms.

Or consider vertebroplasty—injecting a cement-like substance into fractured vertebrae to reduce back pain. Again, the theory is appealing: stabilize the bone, reduce the pain. But a 2009 NEJM study using a sham procedure found no meaningful difference in outcomes. Another example where biological plausibility didn’t translate to real-world results.

Why We Keep Falling for Health Hype

So, why does this kind of hype continue to flourish?

One reason is financial. Health is a $5 trillion industry, and supplements alone generate over $150 billion a year. Many podcast hosts and professionals selling solutions have direct financial stakes. Even well-meaning providers may fall into what I call “self-serving sloppiness”—genuinely believing in a theory because it aligns with their practice or product.

But another reason is more human. Many people live with chronic symptoms that medicine doesn’t always solve—fatigue, poor sleep, vague aches and pains. When traditional approaches fall short, we’re drawn to hopeful narratives, especially when wrapped in compelling stories or flashy buzzwords like “anti-aging,” “detox,” or “immune-boosting.”

Seven Ways to Guard Against the Hype

This makes it even more important to stay grounded. So here are seven actions I recommend to cut through the hype and anchor your decisions in credible health information:

1. Be curious, but demand human evidence. Ask whether the claim has been tested in people through well-designed studies—not just in mice or petri dishes. For a helpful resource, I often turn to Examine.com, which reviews supplement research without commercial bias.
2. Follow the money. If the person promoting a product profits from it, be skeptical. Financial incentives can distort even well-intentioned advice.
3. Watch for red-flag phrases. “Miracle cure,” “natural detox,” “secrets doctors won’t tell you”—these are emotionally loaded terms that rarely signal scientific rigor.
4. Understand the placebo effect. Feeling better doesn’t always mean the treatment worked. Especially when symptoms fluctuate naturally, we may attribute improvement to whatever we tried last. (For more, listen to Episode 28 on the placebo effect.)
5. Ask better questions. Instead of “Did it work?” ask, “Compared to what?” In whom? Over what time? With what risks?
6. Be an open-minded skeptic. Not all theories are wrong. High cholesterol is linked to cardiovascular disease, and statins—after extensive RCTs—proved to be effective. Good science takes time, replication, and scrutiny.
7. Talk to evidence-literate providers. Discuss these ideas with clinicians who understand and respect research. If your doctor isn’t open to these conversations, it may be time to find one who is. (More on that in Episode 20.)

Final Thoughts: Stay Curious, Stay Critical

At the end of the day, we all want to live long and well—but hype won’t get us there. What will? Trusting science that’s been tested, replicated, and applied in people—not just petri dishes or rodent models.

So the next time a friend shares a can’t-miss supplement or a podcast promises to reverse aging with a single hack, pause. Ask questions. Be curious, but be critical. Because when it comes to your health, confidence should come from evidence—not marketing.

Until next time—stay skeptical, stay empowered, and keep pursuing evidence-based wellness.
