About this episode
Dr. Gregory Marcus discusses the health effects of coffee consumption and his research in cardiology.
Dr. Gregory Marcus is the Associate Chief of Cardiology for Research at UCSF Health and an Associate Editor of JAMA. JAMA is an international peer-reviewed general medical journal published online daily and in print weekly. He joined Coffee People when I reached out to him after reading his co-authored paper Acute Effects of Coffee Consumption on Health among Ambulatory Adults (2023). In it, I read this line, "CONCLUSIONS: In this randomized trial, the consumption of caffeinated coffee did not result in significantly more daily premature atrial contractions than the avoidance of caffeine." It felt very relevant to my life (and that of our audience) considering I drink copious amounts of coffee. In this podcast we chat about how his passion for coffee turned into a long term research effort into how beverages like coffee and alcohol engage and impact the human body.
