ZOE Science & Nutrition
Intro
This chapter addresses the pressing issue of heart disease, noting its prevalence as a leading cause of death worldwide. It emphasizes the importance of lifestyle changes, including diet and sleep, in reducing heart disease risk while starting with an engaging listener Q&A.
Heart disease is the world’s biggest killer—and it often strikes without warning. It’s responsible for around 1 in 5 deaths in the US. While these figures are deeply worrying, heart disease is not inevitable.
Decades of research have unearthed many of the risk factors associated with heart health, like poor diet or a sedentary lifestyle. In this episode, Dr. Nour Makarem outlines the latest scientific discoveries in this field and unveils some less-familiar risk factors. Drawing from large-scale population data and the latest wearable tech, she uncovers what makes heart disease so hard to spot, and what we can do today to prevent it.
Nour is a cardiovascular epidemiologist at Columbia University, whose research focuses on how our behaviors—like sleep, stress, and daily rhythms—impact heart disease risk. Her research has helped shape the American Heart Association’s Essential Eight guide to heart health.
