What is the Cardiac Diet?

The cardiac diet, also known as the DASH diet, heart-healthy diet, or low-sodium diet, can help to improve heart health and reduce the risk of heart disease by prioritizing foods that help lower high blood pressure, manage cholesterol levels, reduce inflammation, and support healthy blood vessels.

A cardiac diet is not a quick fix or a restrictive plan that cuts out everything you enjoy. It’s a practical, sustainable approach to eating that emphasizes heart-healthy foods and reduces ingredients known to put a strain on the cardiovascular system.

Why is a heart healthy diet important for cardiovascular health?

Heart disease remains the leading cause of death in the United States.¹But, the good news is that many of its risk factors are manageable, especially through diet. What you eat every day directly affects your blood pressure, cholesterol levels, and overall heart health. , as Dr. Manoj Pawar, Chief Medical Officer at Mutual of Omaha, explains that “it is never too late to start; if you already have cardiac disease, hypertension, or pre-diabetes, you can dramatically improve your situation by making simple dietary changes now.”

Best Diets for a Healthy-Heart

The best diets for hypertension emphasize fruits and vegetables, whole grains, and healthy fats. Dr. Pawar recommends the DASH and Mediterranean diets, noting that they are “excellent because they prioritize four to five daily servings of fruits and vegetables while incorporating nuts and olive oil as healthy fat sources.”

Mediterranean diet for heart health

Mediterranean diets emphasize healthy monounsaturated fats, particularly from extra-virgin olive oil, alongside a high intake of fruits, vegetables, whole grains, and omega-3-rich fish. This eating pattern is widely recognized for its anti-inflammatory effects and its documented ability to reduce the risk of major adverse cardiovascular events. By focusing on nutrient-dense, minimally processed foods, it helps improve lipid profiles and supports overall vascular integrity, making it a cornerstone of long-term heart protection.²

Category	Recommended Foods	Heart Health Benefit
Healthy Fats	Extra-virgin olive oil, avocados	Provides monounsaturated fats that lower LDL (bad) cholesterol.
Proteins	Salmon, mackerel, sardines, beans	High in Omega-3 fatty acids to reduce inflammation.
Produce	Tomatoes, leafy greens, berries	Rich in antioxidants that protect blood vessels.
Whole Grains	Farro, barley, whole-grain bread	High fiber content helps regulate blood sugar and digestion.
Nuts & Seeds	Walnuts, almonds, flaxseeds	Supports arterial health and provides healthy plant proteins.

DASH diet for heart health

The DASH diet (Dietary Approaches to Stop Hypertension) is specifically designed to manage blood pressure by prioritizing foods rich in potassium, calcium, and magnesium while significantly limiting daily sodium intake.¹It encourages the consumption of fruits, vegetables, whole grains, and low-fat dairy, which work together to lower both systolic and diastolic pressure.

Category	Recommended Foods	Heart Health Benefit
Low-Fat Dairy	Skim milk, low-fat Greek yogurt	Provides calcium and vitamin D to support vascular function.
Potassium-Rich	Bananas, sweet potatoes, spinach	Helps the body flush out sodium and eases tension in blood vessel walls.
Lean Proteins	Skinless poultry, white fish, lentils	Minimizes saturated fat intake while providing essential muscle support.
Whole Grains	Brown rice, oatmeal, quinoa	Essential for maintaining healthy blood pressure and weight.
Seeds & Legumes	Sunflower seeds, kidney beans, peas	High in magnesium, which is critical for regulating heart rhythm.

Plant based diet for heart health

Plant-based diets tend to be lower in saturated fats and cholesterol, and higher in fiber, antioxidants, and anti-inflammatory compounds, making it one of the best diets for heart health. These factors work together to help lower blood pressure, reduce bad cholesterol (LDL), improve blood vessel function, and reduce the buildup of plaque in arteries.

Category	Recommended Foods	Heart Health Benefit
Plant Proteins	Lentils, chickpeas, tofu, tempeh, edamame	High in fiber and arginine, which improves vascular function and lowers LDL.
Produce	Spinach, kale, berries, cruciferous vegetables	Packed with nitrates and antioxidants that reduce arterial stiffness.
Whole Grains	Steel-cut oats, quinoa, barley, brown rice	Provides soluble fiber to help clear cholesterol from the bloodstream.
Healthy Fats	Avocados, walnuts, flaxseeds, chia seeds	Rich in Alpha-Linolenic Acid (ALA) to support healthy heart rhythms.
Plant-Based Dairy	Unsweetened soy or almond milk, soy yogurt	Fortified with calcium and vitamin D without the saturated fats found in whole milk.

Heart-healthy foods to add to your diet

When it comes to the best foods for preventing heart disease and lowering cholesterol, it’s not about following the latest trend, it’s about returning to basics and choosing foods that offer real nutritional value.

1. Nuts and seeds

Nuts (both whole and as nut butter) and seeds of all types are a significant source of healthy fats, fiber, and plant-based protein. Walnuts, for example, are rich in omega-3 fatty acids, and studies show that others, like pecans, can help reduce LDL (bad) cholesterol. ¹

2. Berries

Blueberries, strawberries, and raspberries, either fresh or frozen, are all rich in antioxidants and polyphenols, which support blood vessel health. They’re easy to snack on or to add nutrition to things like yogurt or oatmeal.

3. Fatty fish

Oily fish like salmon, sardines, trout, and mackerel are rich in omega-3 fatty acids. These healthy fats can help reduce inflammation, lower triglyceride levels, and support a healthy heart rhythm.

4. Leafy greens

Leafy green, fiber-rich vegetables like spinach and kale are packed with nutrients that support cardiovascular health, including nitrates, potassium, and folate. Include a serving or two daily, either raw in salads or lightly cooked.

5. Whole grains

Whole grains such as oats, brown rice, quinoa, and barley provide fiber and essential nutrients. They help lower cholesterol and regulate blood sugar, which are both important for heart health. Choose whole grain bread and pasta over white, and check labels to ensure you’re getting true whole grains.

6. Legumes

Beans, lentils, and chickpeas are high in fiber, protein, and potassium. You can use them to replace the meat in soups, stews, or side dishes, or on their own as a powerful source of heart-healthy protein.

7. Avocados

Avocados provide heart-healthy monounsaturated fats and potassium, nutrients that help reduce blood pressure and support proper heart function. A half avocado a day is plenty, slice it into salads or spread it on whole grain toast.

8. Olive oil

Extra virgin olive oil is a staple of the Mediterranean diet, which has long been associated with heart health. It’s rich in antioxidants and healthy fats, and makes an excellent replacement for butter or margarine. Use it for cooking, salad dressings, or dipping bread.

Foods to limit or avoid on the cardiac diet

As well as eating plenty of heart-healthy foods, a heart-healthy diet plan also means cutting back on certain foods that contribute to high blood pressure, high cholesterol, and inflammation.

Processed meats: Bacon, sausage, deli meats, and hot dogs often contain high levels of sodium and saturated fats, both of which increase heart disease risk. Opt for leaner, unprocessed proteins.
Refined carbohydrates: White bread, pastries, and sugary cereals can spike blood sugar and provide little nutritional value. Swap them out for whole grain options that support sustained energy and better heart function.
Sugary drinks: Soda, sweetened teas, and even many fruit juices are packed with sugar that adds empty calories and contributes to insulin resistance² and weight gain. Water, herbal teas, and black coffee are healthier choices.
Excess salt: Too much sodium raises blood pressure, which forces the heart to work harder. Watch out for high-salt packaged foods, canned soups, and fast food. Cooking at home lets you control how much salt you eat.
Alcohol: Excessive alcohol intake can lead to high blood pressure, heart failure, and an increased calorie count that contributes to weight gain. While moderation is often discussed, reducing or eliminating alcohol is a significant step in managing cardiovascular health. Dr. Pawar advises, “If you are struggling to control your blood pressure, one of the most effective ‘hidden’ triggers to eliminate is daily alcohol consumption.”
