Science-based nutrition to prevent a heart attack | Michelle Routhenstein, MS, RD

Cardiovascular disease remains the leading cause of death globally, yet 80 to 90 percent of cases are preventable through evidence-based nutrition and lifestyle modifications. Preventive cardiology dietitian Michelle Routhenstein emphasizes the necessity of moving beyond vague dietary labels like "Mediterranean" or "vegan" toward personalized, nutrient-adequate patterns that address individual biomarkers such as ApoB, blood pressure, and systemic inflammation. Key strategies include increasing soluble fiber intake to manage cholesterol, optimizing the sodium-to-potassium ratio for vascular health, and prioritizing gut health to support nitric oxide production. Rather than relying on restrictive calorie counting or fear-based myths regarding carbohydrates and seed oils, sustainable heart health requires consistent, habit-based changes. By monitoring metrics like waist circumference and blood pressure at home, individuals can transition from anxiety-driven decision-making to an empowered, data-informed approach that stabilizes arterial plaque and improves long-term healthspan.
