About This Episode:

The Multiple Risk Factor Intervention Trial (MRFIT) was a groundbreaking clinical trial conducted in the 1970s and 1980s. Its main objective was to investigate the relationship between various risk factors and the incidence of heart disease.

The study aimed to determine whether modifying risk factors, such as high blood pressure, high cholesterol levels, and smoking, could lead to a reduction in cardiovascular events.

The trial spanned several years, with participants being followed up for a period of approximately six years to assess the incidence of cardiovascular events and mortality. The primary outcome measures included coronary heart disease (CHD) mortality and overall mortality.

The MRFIT trial yielded several important findings that have significantly influenced our understanding of cardiovascular health and prevention strategies.

In this episode we take a look at why this is such seminal research, as well as the contribution of one of the greatest researchers ever in the field, Jeramiah Stamler.


Sigma Nutrition Radio, hosted by nutrition scientist Danny Lennon, moves beyond the noise of diet trends and simplistic advice to explore the complex, fascinating world of human nutrition. This is a space for deep, evidence-based conversations that acknowledge the nuance and often contradictory nature of scientific research. Each episode delves into a specific topic within health, fitness, or dietetics, breaking down the underlying physiology, examining the latest studies, and discussing practical implications with expert guests. The goal isn't to hand out rigid meal plans but to cultivate the critical thinking skills necessary to navigate the ever-changing landscape of nutritional science. You'll hear detailed analyses of how research is conducted, thoughtful debates on contentious issues, and explorations of how evidence translates-or doesn't-into real-world recommendations for different individuals. Tuning into this podcast means committing to a more sophisticated understanding of how food, movement, and metabolism interact, leaving you better equipped to make informed decisions about your own health and skepticism towards the next big headline. Danny’s approach is both rigorous and accessible, making even the most detailed biochemical pathways relevant to everyday life. It’s for anyone who has ever wondered about the real story behind a nutrition claim and values substance over soundbites.
