What Cardiovascular Disease Is
Cardiovascular disease is a broad term for conditions involving the heart and blood vessels, including coronary artery disease, heart attack, stroke, and other disorders. Risk is influenced by many factors, including blood pressure, cholesterol, diabetes, smoking, family history, age, physical activity, and diet.
Because cardiovascular disease includes many different diagnoses, food recommendations may need to change when heart failure, kidney disease, diabetes, anticoagulant use, or other medical issues are present.
What Research Tells Us About Nutrition
The American Heart Association emphasizes dietary patterns rather than isolated nutrients. A heart-healthy pattern includes a variety of vegetables and fruits, mostly whole grains, healthy protein sources, and unsaturated fats in place of saturated fats.
Lower sodium intake can be important for blood pressure, while soluble fiber and replacing saturated fats with unsaturated fats can help improve LDL cholesterol. The appropriate targets still depend on the individual.
Foods and Nutrients Discussed in the Evidence
The strongest evidence supports overall food patterns built from mostly minimally processed foods.
Vegetables and fruits
A wide variety contributes fiber, potassium, and other nutrients.
Whole grains and fiber
Oats, barley, brown rice, and other whole grains can help increase fiber intake.
Unsaturated fats
Olive oil, avocado, nuts, seeds, and fish can replace foods high in saturated fat.
Beans and legumes
Beans, lentils, and peas provide plant protein and fiber.
Fruit instead of added sugar
Whole fruit can add sweetness along with fiber and micronutrients.

When Individualized Help Matters
If you have heart failure, kidney disease, diabetes, difficulty swallowing, an anticoagulant prescription, or a specific sodium or fluid limit, generic heart-health advice may not be enough.
Medication remains important when prescribed. Food choices should complement, not replace, treatment recommended by your healthcare team.
