European Cardiology Experts Rank the Best Diets for Heart Disease Prevention
A major ESC scientific statement distills the latest evidence on diet, nutrients, and eating patterns for cardiovascular disease prevention.
Summary
A 2025 scientific statement from the European Society of Cardiology reviews evidence on diet and cardiovascular disease (CVD) risk. Plant-based diets rich in minimally processed foods reduce CVD risk, while ultra-processed foods, excess meat, salt, sugar, and saturated fat increase it. Mediterranean, DASH, and vegetarian diets show clear benefit; vegan diets offer no additional advantage. Low-carbohydrate diets appear promising but lack long-term confirmation. Fasting strategies and balanced meal timing show favorable effects. Moderate coffee is safe; one alcohol unit daily may modestly reduce CVD risk. Vitamin and mineral supplements largely show no benefit, though high potassium intake helps and high sodium is harmful. The statement urges clinicians to incorporate dietary assessment into routine cardiovascular care.
Detailed Summary
Cardiovascular disease remains the leading cause of death globally, and diet is one of the most modifiable risk factors. Despite this, many health professionals lack a clear, evidence-based framework for dietary counseling. This scientific statement from the European Association of Preventive Cardiology addresses that gap by synthesizing current research across dietary patterns, individual foods, and specific nutrients.
The review evaluated the impact of dietary patterns, specific foods, vitamins, minerals, and plant-derived bioactive compounds on CVD risk biomarkers. Evidence was drawn from existing research rather than a new clinical trial, positioning this as a comprehensive evidence appraisal and clinical guidance document.
Key findings confirm that plant-based dietary patterns — particularly the Mediterranean diet and DASH diet — are consistently associated with reduced CVD risk. Vegetarian diets also demonstrate benefit, while vegan diets showed no incremental advantage over other plant-forward approaches. Ultra-processed foods, red and processed meats, high sodium, added sugars, and saturated fats were linked to elevated CVD risk. Low-carbohydrate diets may help but require longer-term study. Intermittent and time-restricted fasting strategies can reduce CVD risk, though adherence remains a practical challenge. Moderate coffee consumption poses no cardiovascular harm, and one alcoholic drink per day may carry a modest protective signal.
On the supplementation front, the evidence is largely null — vitamins and minerals in supplement form do not reduce CVD risk for most people. High dietary potassium is beneficial in healthy individuals, while high sodium intake is clearly detrimental.
The clinical implications are significant: cardiologists, nurses, and allied health professionals are encouraged to routinely assess patients' diets and deliver evidence-based nutritional guidance as a core component of cardiovascular prevention strategies.
Key Findings
- Mediterranean and DASH diets consistently reduce CVD risk; vegan diets offer no additional benefit over vegetarian approaches.
- Ultra-processed foods, saturated fat, excess sodium, and red meat are associated with increased cardiovascular risk.
- Fasting strategies (intermittent, time-restricted, alternate-day) can reduce CVD risk but face adherence challenges.
- Vitamin and mineral supplementation generally does not reduce CVD risk; high potassium intake is beneficial.
- Moderate coffee consumption is safe; one alcohol unit per day may modestly lower cardiovascular risk.
Methodology
This is a scientific statement — a structured evidence review and expert consensus document — not a primary clinical trial or meta-analysis. Authors appraised existing research on dietary patterns, specific foods, and micronutrients in relation to CVD risk biomarkers. No new data collection was performed.
Study Limitations
The statement is based on a review of existing evidence, which varies widely in study design, duration, and population, limiting causal conclusions. Long-term effects of low-carbohydrate diets and fasting regimens remain insufficiently characterized. The modest benefit attributed to one daily alcoholic drink should be interpreted cautiously given evolving evidence on alcohol and cancer risk.
