"Drinking more than 400 mg of caffeine daily could increase cardiovascular disease risk"—this headline terrified coffee drinkers everywhere. But the study making waves was just a conference presentation measuring heart rate recovery after a three-minute step test on 92 people, not published research tracking actual disease outcomes. In this episode, we expose how a preliminary finding with 18 high-caffeine participants became a global health scare while contradicting decades of research on 1.2 million people showing coffee may actually be protective. You'll discover why conference abstracts aren't settled science, how acute physiological responses get twisted into disease predictions, and what the actual evidence on caffeine and heart health really shows. It's a masterclass in why health headlines flip-flop—and why your morning coffee is probably fine.
