In this episode of Live Long and Well, I'm joined by Dr. Anthony Pearson, a board-certified cardiologist known for his evidence-based yet refreshingly skeptical take on mainstream cardiac care. Together, we explore the nuanced science behind heart health and how you can make smarter decisions to protect your cardiovascular system—starting today.

We open by recognizing that heart disease remains the leading cause of death for both men and women. While many of the six pillars of longevity—from exercise to stress reduction—play protective roles, today’s episode zooms in on two powerful, sometimes polarizing topics: the role of diet in heart health and the value of coronary artery calcium (CAC) scans.

Dr. Pearson shares how a personal brunch conversation with his wife challenged decades of low-fat dietary dogma, prompting his transformation into the "Skeptical Cardiologist." Here is a summary showing that dairy won't increase risk of cardiovascular disease. He recounts the 

We dive into the broader saturated fat debate, highlighting how different fat sources have varied effects on cholesterol and cardiovascular risk. While dairy fats may be benign or even beneficial, others—particularly those consumed in excess on paleo or keto diets—can raise LDL cholesterol substantially. Dr. Pearson discusses the Keto-CAD Study, which found that even lean, low-risk keto followers may build up arterial plaque if their LDL levels skyrocket.

The conversation then shifts to the calcium heart or CAC scan, a non-invasive $100 screening test that quantifies calcified coronary artery plaque via CT imaging. While traditional risk calculators like the pooled cohort equations often fall short, CAC scoring offers a personalized look at actual plaque burden—critical since many heart attacks occur in people not flagged as high-risk. As Dr. Pearson explains, a high score doesn’t mean you will need surgery. Instead, it’s typically a cue for lifestyle and medication adjustments, not invasive procedures. He references the ISCHEMIA Trial, which found no benefit from stenting stable, asymptomatic patients over optimized medical therapy.

We close with practical advice: talk to your doctor, especially if you have a family history or fall in that “borderline risk” zone where a CAC score might influence your care plan. And yes, it should be okay to keep enjoying that butter—as long as you’re informed and mindful and don't overdue it.

Takeaways: Full-fat dairy is not the enemy—it may even be heart-protective. If your LDL skyrockets on keto, that’s a red flag worth addressing. CAC scans can personalize your prevention plan and offer peace of mind or a critical nudge toward action. Want more clarity on your own heart health journey?
