The War on Fat: The Seven Countries Study

# Summary

In this episode, Josh and Chuck dive into the famous Seven Countries Study conducted by Dr. Ansel Keys in the 1950s, which fundamentally shaped America's anti-fat dietary guidelines and the food pyramid that influenced generations. They explore how Keys' research linking saturated fat to heart disease became the foundation for decades of low-fat food trends, which ironically may have contributed to the obesity and diabetes epidemics we see today. The hosts break down the study's findings, examine its significant methodological flaws as an ecological study that confused correlation with causation, and discuss how subsequent research suggests that processed foods combining sugar and fat, rather than fat alone, might be the real culprit behind heart disease.
