They want you to panic when science changes. Headlines, social chatter, and loud voices online often make it sound like science can’t be trusted. That every flip in guidance is a failure. But the truth is very different. In this episode of Health Savvy You, we dig into the real story behind shifting health advice. From ghee to lobotomies and thalidomide, science has made mistakes, but it has also corrected them, learned from them, and saved millions of lives along the way. We explore how vaccines, handwashing, antiretroviral therapy for HIV, water sanitation, and seat belts all demonstrate the power of evidence-based science. And sometimes, predictions made years ago come true like mosquitoes appearing in Iceland as climate change reshapes ecosystems. We’ll unpack why science evolves, how uncertainty is a sign of honesty, and why trusting the process, even when guidance changes, is safer than following fear-driven narratives. By the end, we hope you’ll see that change in science isn’t a reason to panic. It’s proof that the system works, that evidence wins, and that curiosity, correction, and learning keep us healthier and safer every day.
