Ep. 359: Dr. Kim Williams Breaks Down the New Heart Health Guidelines (and it’s Great News for Plants!)

The newest AHA and ACC guidelines for treating dyslipidemia are here — and according to Dr. Kim Williams, they mark a powerful shift toward prevention, earlier testing, and whole-food, plant-based nutrition as the foundation of cardiovascular care.

Rip welcomes back Dr. Kim Williams, past president of the American College of Cardiology, for a practical and deeply encouraging breakdown of what these updated cholesterol guidelines mean for everyday people.

Dr. Williams explains why cardiovascular risk is no longer just about one cholesterol number. Instead, clinicians are being encouraged to look at the whole picture: LDL cholesterol, ApoB, Lp(a), inflammation, blood pressure, blood sugar, kidney function, family history, lifestyle, and coronary artery calcium when appropriate.

The most exciting part for the PlantStrong community? Lifestyle optimization is now treated as the clinical foundation — and Dr. Williams is clear about what that means: a whole-food, plant-based diet built around beans, grains, nuts, seeds, fruits, vegetables, and mushrooms, along with exercise, sleep, mindfulness, strong social connections, and avoidance of tobacco, alcohol, and other harmful substances.

This conversation also tackles statins, PCSK9 inhibitors, Lp(a), coronary calcium scoring, and the new philosophy of treating risk lower, earlier, and longer — always with food first, and medication when needed.

Key Takeaways

• The new cholesterol guidelines emphasize lifestyle first, not lifestyle as an afterthought.
• Dr. Williams says a whole-food, plant-based diet should be built around beans, grains, nuts, seeds, fruits, vegetables, and mushrooms.
• LDL cholesterol is still important, but it is no longer the only number that matters.
• ApoB may give a clearer picture of risk in some people, especially those with diabetes, high triglycerides, or central obesity.
• Lp(a) is largely genetic and should be measured at least once in adulthood; the 2026 guideline includes updated recommendations for elevated Lp(a).
• Coronary artery calcium scoring can help personalize risk and guide LDL targets.
• Dr. Williams emphasizes that the goal is not “plants versus statins.” It is whole plant foods first, medications when needed.
• The overall prevention philosophy is: lower, earlier, longer.
