Cardiovascular Disease & Nutrition
Food and nutrition information related to cardiovascular disease, based on current research and established guidance.
Nutrition is one part of cardiovascular health. Current guidance focuses on the overall eating pattern rather than a single food, nutrient, or “heart-healing” recipe.
What Cardiovascular Disease Is
Cardiovascular disease is a broad term for conditions affecting the heart and blood vessels. It includes coronary artery disease, heart attack, stroke, heart failure, and other disorders with different causes and treatment needs.
Food choices can influence several cardiovascular risk factors, including blood pressure, blood lipids, blood glucose, and body weight. Nutrition does not replace prescribed medicines, procedures, or individualized medical care.
What Research Tells Us About Nutrition
The American Heart Association’s 2026 dietary guidance emphasizes a pattern rich in vegetables and fruits, whole grains, healthy protein sources, and unsaturated fats, while minimizing added sugars, excess sodium, saturated fat, and highly processed foods.
The evidence is strongest for the overall pattern. Replacing foods high in saturated fat with sources of unsaturated fat, choosing fiber-rich foods, and reducing sodium are more evidence-based than relying on individual “superfoods” or supplements.
Foods and Nutrients Discussed in the Evidence
These examples reflect the evidence and guidance summarized above. Their role can vary depending on individual needs.
Vegetables and fruits
A wide variety provides fiber, potassium, and other nutrients within a heart-healthy pattern.
Whole grains
Oats, barley, brown rice, whole-grain breads, and other intact grains add fiber and can replace refined grains.
Healthy proteins
Beans, lentils, nuts, seeds, fish, and lean poultry can fit a heart-healthy eating pattern.
Unsaturated fats
Olive and other liquid plant oils, nuts, seeds, avocado, and fish provide unsaturated fats.
Lower-sodium choices
Cooking more often from basic ingredients and comparing labels can reduce sodium from packaged and restaurant foods.
Everyday Meal Ideas
These are general examples of how evidence-based nutrition principles can look in ordinary meals. They are not individualized treatment plans.
When Individualized Help Matters
People with heart failure, kidney disease, diabetes, swallowing problems, or prescribed sodium or fluid limits may need recommendations that differ from general heart-healthy guidance.
If you have cardiovascular disease, use nutrition information alongside the treatment plan from your clinician. Do not stop or change prescribed medicines based on a food guide.
