A Clinician's Guide to Healthy Eating for Cardiovascular Disease Prevention

Patients ask “what should I eat for my heart?” and clinicians, short on nutrition training and time, often struggle to answer well. This review is built to fix that — a practical eating guide for cardiovascular prevention.

The evidence converges on a few patterns: DASH, Mediterranean, and vegetarian diets have the strongest support, all emphasizing fruits, vegetables, whole grains, legumes, nuts, and fish while minimizing trans and saturated fats, refined carbohydrates, sodium, red and processed meats, and sugar-sweetened beverages. Notably, the authors stress adapting this to real lives — including lower-income settings — rather than prescribing an idealized diet few can follow.

The practical takeaway is a concrete counseling framework: steer patients toward DASH/Mediterranean-style eating, swap sugary drinks for water, go plant-forward, and tailor to culture and budget. The resistance comes from food-industry interests and the practical barriers of time and training in clinic.

We rate the evidence moderate: a comprehensive, low-conflict narrative synthesis of trials, meta-analyses, and guidelines, but not a systematic review. Its clinical significance is solid and practical — diet is foundational to prevention, and an actionable, equity-minded framework is genuinely useful at the point of care.
