Too Much Sitting, "Spiky" Cholesterol, and Heart Disease

Biomechanist Katy Bowman and biologist Dr. Jeannette Loram unpack emerging research on heart disease, inflammation, cholesterol, and arterial plaque. Inspired by a recent Scientific American article, they explore what plaque is, how and why it forms, and how blood flow patterns influence where plaque accumulates in the arteries. They discuss recent evidence that places inflammation as a foundational piece of heart disease and how the ‘spiky’ shape and structure of cholesterol in plaque has a direct role in the inflammatory pathways and immune system overreactions that occur in heart disease. 

Katy and Jeannette offer practical insights into how regular activity, varied positioning, and lifestyle choices can help support healthy arteries. They also discuss the importance of scientific curiosity, prevention over treatment, and why understanding the body's processes can inspire better self-care.
