Several diets follow the general pattern for heart-healthy eating listed above. These diets include:
- Mediterranean diet: This diet focuses on fruits and vegetables, whole grains, legumes, and olive oil.
- Dietary approaches to stop hypertension (DASH): The DASH diet is intended to help lower blood pressure. It promotes eating plant-based whole foods while avoiding salt, sugar, and most fats.

very similarto the DASH diet. It recommends choosing nutrient-dense foods across food groups, and limits salt, sugar, and saturated and trans fats.
- Vegetarian whole-food diets: Replacing animal proteins with plant-based sources such as legumes and nuts can
benefit heart health.
Fruits and vegetables
The phrase “eat the rainbow” is a useful way to remember to consume a variety of different colored fruits and vegetables each day. The different types of antioxidants that plant foods contain can help protect the heart.
Fruits and vegetables are also good sources of fiber, which is essential for heart health.
Experts suggest eating
People should try to focus on eating non-starchy vegetables and limiting portion sizes of starchy vegetables, such as potatoes and squash.
Consider colorful fruits and vegetables such as:
- spinach and other leafy green vegetables
Oily fish contains omega-3 fatty acids, which have anti-inflammatory properties and are good for the heart.
Fish that are high in omega-3 fatty acids include:
Some people should use extra caution about what types of fish to eat. This includes:
- people who are trying to become pregnant
- pregnant people

- whole grain bread
- whole grain pasta
- brown rice
Nuts, seeds, and legumes
The best diets for cardiovascular health include
Legumes such as beans, tofu, and chickpeas are generally lower in calories than nuts and seeds. Nuts and seeds are very energy-dense, and some are expensive. Depending on a person’s budget and desired calorie intake, they may choose to eat larger volumes of legumes and smaller servings of nuts and seeds.
A person may wish to try adding the following to their diet:
- Nuts: These include peanuts, walnuts, almonds, Brazil nuts, hazelnuts, pecans, and cashews.
- Seeds: These include sunflower seeds, pumpkin seeds, flaxseeds, hemp seeds, and chia seeds.
- Legumes: These include soybeans and soy products such as tofu and tempeh, chickpeas, lentils, black beans, kidney beans, adzuki beans, and fava beans.
Low fat dairy foods
However, it says that most of the evidence suggests that people should consume less saturated fat in their diet. A person can consume less saturated fat by choosing nonfat and low fat dairy products, such as:
People who choose to include meat in a cardiac diet are encouraged to select lean cuts of meat that are unprocessed. Saturated fats and other substances found in red and processed meats may harm heart health.
Unprocessed lean meats include:
- skinless poultry

- wild game
People who choose to eat red meat as part of a cardiac diet may benefit from choosing the leanest cuts available. For ground beef, look for

Sugar-sweetened foods and beverages
Many processed foods and beverages contain added sugars, especially sodas and energy drinks.
The Dietary Guidelines for Americans recommend limiting calories from added sugars to no more than
Avoiding excess sugar may help a person reach or maintain a moderate weight and prevent heart disease.
Processed foods often contain long lists of ingredients, many of which are not beneficial for a healthy heart. For example, many processed foods contain:
- high sugar
- high salt
- trans fats
- saturated fat
- additives and food colorings
When possible, try to cook meals from scratch using whole foods, and choose whole food snacks.
Refined carbohydrates lack fiber and can cause a person to feel hungry again quickly. Replacing refined carbohydrates with nutrient-dense whole grains lowers the risk of many conditions, including stroke and metabolic syndrome.
Some refined carbs to limit include:
- white bread, pasta, and rice
- cakes, cookies, and pastries
- many breakfast cereals
- pizza dough
- white flour

The cardiac diet plan suggests consuming little or no alcohol. People who consume alcohol may wish to consider doing so in moderation. This means consuming no more than one drink per day for females and no more than two drinks per day for males.
Some people believe that a moderate intake of red wine can help protect the heart because it contains antioxidants. However, the evidence for this is weak, according to the
Many processed foods contain added salt, so a person can monitor their intake by reading the labels and instead choosing whole foods, when possible. Eating foods cooked at home with limited or no salt, rather than restaurant foods or takeout, can also help lower salt intake.

- Breakfast: Try overnight oats topped with flaked almonds and blueberries. Serve with low fat yogurt.
- Lunch: Try a salmon and avocado salad, including green leaves, peppers, red onion, tomatoes, cucumber, and a squeeze of lemon.

A person may wish to try making gradual changes, maybe two each week. This is preferable to making many changes all at once and then giving up quickly.

On an individual level, making a cost-effective meal plan that meets a person’s specific needs is one way to help make a cardiac diet more accessible. Consider planning meals for the week, and prioritizing ingredients that are frozen or can be stored safely for longer periods of time.
When eating restaurant meals or takeout, a person can aim for dietary choices that follow the cardiac diet. Some restaurants label menu items as low calorie, low sodium, “healthy,” or “light” choices.
Some options that a person may choose to eat at restaurants include:
- skinless poultry
- fish or seafood
- legumes such as black beans, lentils, or tofu

- exercising regularly
- avoiding long periods of sitting
