Explore science-backed heart disease diets, including key foods, eating patterns, and lifestyle choices proven to support cardiovascular health.

Heart disease remains the leading cause of death worldwide. Fortunately, research consistently shows that dietary patterns, specific foods, and lifestyle choices can significantly impact cardiovascular risk. This guide synthesizes leading scientific advice, practical nutrition tips, and evidence-based eating patterns to help you protect your heart and improve long-term health.

How Diet Affects Your Heart Health

Your diet influences critical risk factors for heart disease 9mdash;such as cholesterol levels, blood pressure, blood sugar, and body weight 9mdash;by providing the building blocks (proteins, fats, carbohydrates, vitamins, minerals) for each cell in your body. While you cannot change some risk factors for heart disease, such as age or genetics, diet remains a powerful area where you can intervene to lower your risk.

High Blood Pressure (Hypertension): Diets high in potassium, magnesium, fiber, and antioxidants 9mdash;typical of fruit, vegetables, whole grains, and lean proteins 9mdash;can help lower blood pressure and reduce strain on the heart.
High Blood Lipids: Eating high-fiber foods and minimizing added sugars and processed fats can lower cholesterol and triglycerides, reducing risk of atherosclerosis and coronary events.
High Blood Sugar: Diets low in processed carbohydrates and added sugars help regulate blood sugar levels and insulin resistance, mitigating the risk for diabetes and related heart complications.
Excess Body Weight: Choosing nutrient-dense, high-fiber foods over calorie-dense processed products can prevent unhealthy weight gain and obesity 9mdash;key contributors to heart disease.

What Does a Heart-Healthy Diet Include?

The American Heart Association and leading experts advocate a diet based on a wide variety of nutrient-rich foods. Heart-healthy eating emphasizes vegetables, fruits, whole grains, lean proteins, plant-based fats, and limits processed or sugary foods.

Fruits and Vegetables: Aim for a spectrum of colors to maximize nutrient intake.
Whole Grains: Oats, brown rice, whole wheat, barley, and quinoa provide fiber and nutrients.
Legumes and Nuts: Beans, lentils, chickpeas, walnuts, almonds, and soy-based foods support heart health.
Dairy: Prefer low-fat or non-fat options.
Poultry and Fish: Choose lean poultry and include fish (especially oily fish like salmon, mackerel, sardines) at least twice per week for beneficial omega-3 fatty acids.
Healthy Oils: Use olive, avocado, canola, and other unsaturated plant oils.

Fill half your plate with vegetables and fruits at each meal, and choose lean protein and healthy grains for the remainder. Limit portion sizes, especially for calorie-dense foods, and ensure your diet is varied.

Heart-Healthy Dietary Patterns

Decades of research have identified several eating patterns closely associated with reduced cardiovascular risk.

Mediterranean Diet

This diet emphasizes plant-based foods, beans, vegetables, fruits, whole grains, seafood, olive oil, nuts, and seeds. It limits red and processed meats, added sugars, and ultra-processed foods. A 2024 clinical study showed that following a Mediterranean-style diet could nearly halve the risk of heart disease.

Major foods: legumes, leafy greens, tomatoes, fennel, eggplant, fruits (especially berries and citrus), seafood, extra virgin olive oil, nuts, seeds, whole grains
Typical weekly intake: seafood 2 63 times; red meat rarely or never
Often includes moderate amounts of wine (if consumed, do so sensibly)

DASH Diet

The Dietary Approaches to Stop Hypertension (DASH) diet, developed in the 1990s, focuses on lowering blood pressure. It centers on fruits, vegetables, low-fat dairy, lean proteins, and whole grains while sharply limiting sodium, saturated and trans fats.

Limit: processed foods, high-sodium snacks, red meats, sugary beverages
Aim for: fresh produce, lean proteins, and low-fat or non-fat dairy daily

Plant-Based Diets

Vegetarian and vegan diets can support heart health when they emphasize whole, minimally processed plant foods. However, plant-based diets heavy in refined grains, sugary drinks, and ultra-processed snacks may still increase disease risk. The healthiest versions focus on vegetables, beans, nuts, seeds, and whole grains.

Tips to Reduce Heart Disease Risk Through Diet

Limit fried fast food and processed snacks.
Replace saturated fats (butter, cream, coconut oil) with unsaturated plant oils (olive oil, avocado, canola, nut oils).
Increase variety and quantity of plant foods; eat more vegetables, fruits, and wholegrains.
Snack on a handful of raw, unsalted nuts most days of the week (especially walnuts and almonds).
Trim visible fat from meats and skin from poultry before cooking.
Eat legumes regularly: beans, lentils, baked beans (reduced salt), tofu, soybeans.
Eat oily fish at least once per week for omega-3 fatty acids.
Use herbs and spices instead of salt for flavor; reduce sodium intake by choosing low-sodium foods and avoiding processed options.
If elevated cholesterol is a concern, choose low-fat or non-fat dairy and limit egg intake to no more than 7 per week.
If you drink alcohol, moderate your intake (no more than two standard drinks per day).
Be mindful of portion sizes—large servings and snack foods can lead to excessive calorie intake.
Fill at least half your plate with vegetables and fruits.

Managing Key Nutrients

Salt (Sodium)

High sodium intake is linked to elevated blood pressure and increased heart disease risk.
Choose foods with little or no added salt and read labels for sodium content.
Flavor food with herbs, spices, citrus, or vinegar rather than extra salt.

Sugar

Excess sugar raises blood pressure, increases triglycerides, and is linked to weight gain and diabetes.
Limit sugary drinks, desserts, and packaged snacks.
Choose naturally sweet foods—fruits, vegetables—and minimize processed sweets.

Saturated and Trans Fats

Saturated and trans fats increase LDL (“bad”) cholesterol and the risk of heart disease.
Limit sources: fatty cuts of meat, processed meats, full-fat dairy, fried foods, and prepackaged snacks.
Replace with healthy fats from plant-based oils, nuts, seeds, and oily fish.

Alcohol

High alcohol intake raises blood pressure and triglyceride levels.
If you choose to drink, consume in moderation—no more than two standard drinks per day.
Excessive alcohol increases risk for cardiac events and other chronic diseases.

Caffeine

While moderate caffeine intake is typically safe, excessive consumption (more than 400 mg per day) may raise heart rate and blood pressure.
Limit energy drinks and highly caffeinated beverages.
Monitor symptoms and consult with your doctor if you have a cardiac history.

Calcium

Calcium is essential for bone and heart health.
Obtain calcium from dietary sources—primarily low-fat dairy, green vegetables, almonds, fortified foods.
Consider supplements only under medical advice, as over-supplementation may affect heart rhythm or raise cardiovascular risk.
