Heart-healthy diet: 8 steps to prevent heart disease

Changing your eating habits can be tough. Start with these eight strategies to kick-start your way toward a heart-healthy diet.

By Mayo Clinic staff

Although you might know eating certain foods can increase your heart disease risk, it's often tough to change your eating habits. Whether you have years of unhealthy eating under your belt or you simply want to fine-tune your diet, here are eight heart-healthy diet tips. Once you know which foods to eat more of and which foods to limit, you'll be on your way toward a heart-healthy diet.

1. Limit unhealthy fats and cholesterol

Of the possible changes, limiting how much saturated and trans fats you eat is the most important step you can take to reduce your blood cholesterol and lower your risk of coronary artery disease. A high blood cholesterol level can lead to a buildup of plaques in your arteries, called atherosclerosis, which can increase your risk of heart attack and stroke.

The American Heart Association offers these guidelines for how much fat and cholesterol to include in a heart-healthy diet:

Type of fat	Recommendation
Saturated fat	Less than 7 percent of your total daily calories
Trans fat	Less than 1 percent of your total daily calories
Cholesterol	Less than 300 milligrams a day for healthy adults; less than 200 milligrams a day for adults with high levels of low-density lipoprotein (LDL), or "bad," cholesterol or those who are taking cholesterol-lowering medication

The best way to reduce saturated and trans fats in your diet is to limit the amount of solid fats — butter, margarine and shortening — you add to food when cooking and serving. You can also reduce the amount of saturated fat in your diet by trimming fat off your meat or choosing lean meats with less than 10 percent fat.

You can also use low-fat substitutions when possible for a heart-healthy diet. For example, top your baked potato with salsa or low-fat yogurt rather than butter, or use low-sugar fruit spread on your toast instead of margarine.

You may also want to check the food labels of some cookies, crackers and chips. Many of these snacks — even those labeled "reduced fat" — may be made with oils containing trans fats. One clue that a food has some trans fat in it is the phrase "partially hydrogenated" in the ingredient list.

When you do use fats, choose monounsaturated fats, such as olive oil or canola oil. Polyunsaturated fats, found in nuts and seeds, also are good choices for a heart-healthy diet. When used in place of saturated fat, monounsaturated and polyunsaturated fats may help lower your total blood cholesterol. But moderation is essential. All types of fat are high in calories.

Fats to choose	Fats to limit
Olive oil Canola oil Margarine that's free of trans fats Cholesterol-lowering margarine, such as Benecol, Promise activ or Smart Balance	Butter Lard Bacon fat Gravy Cream sauce Nondairy creamers Hydrogenated margarine and shortening Cocoa butter, found in chocolate Coconut, palm, cottonseed and palm-kernel oils

2. Choose low-fat protein sources

Lean meat, poultry and fish, low-fat dairy products, and egg whites or egg substitutes are some of your best sources of protein. But be careful to choose lower fat options, such as skim milk rather than whole milk and skinless chicken breasts rather than fried chicken patties.

Fish is another good alternative to high-fat meats. And certain types of fish are heart healthy because they're rich in omega-3 fatty acids, which can lower blood fats called triglycerides. You'll find the highest amounts of omega-3 fatty acids in cold-water fish, such as salmon, mackerel and herring. Other sources are flaxseed, walnuts, soybeans and canola oil.

Legumes — beans, peas and lentils — also are good sources of protein and contain less fat and no cholesterol, making them good substitutes for meat. Substituting soy protein for animal protein — for example, a soy burger for a hamburger — will reduce your fat and cholesterol intake.

Proteins to choose	Proteins to avoid
Skim or low-fat (1 percent) milk Fat-free or low-fat dairy products, such as yogurt and cheese Egg whites or egg substitutes Fish, especially fatty, cold-water fish, such as salmon Skinless poultry Legumes Soybeans and soy products, for example, soy burgers and tofu Lean ground meats	Full-fat milk and other dairy products Organ meats, such as liver Egg yolks Fatty and marbled meats Spareribs Cold cuts Frankfurters, hot dogs and sausages Bacon Fried or breaded meats

3. Eat more vegetables and fruits

Vegetables and fruits are good sources of vitamins and minerals; they are low in calories and rich in dietary fiber. Vegetables and fruits also contain substances found in plants that may help prevent cardiovascular disease. Eating more fruits and vegetables may help you eat less high-fat foods, such as meat, cheese and snack foods.

Featuring vegetables and fruits in your diet can be easy. Keep vegetables washed and cut in your refrigerator for quick snacks. Keep fruit in a bowl in your kitchen so that you'll remember to eat it. Choose recipes that have vegetables or fruits as the main ingredient, such as vegetable stir-fry or fresh fruit mixed into salads.

Fruits and vegetables to choose	Fruits and vegetables to avoid
Fresh or frozen vegetables and fruits Low-sodium canned vegetables Canned fruit packed in juice or water	Coconut Vegetables with creamy sauces Fried or breaded vegetables Canned fruit packed in heavy syrup Frozen fruit with sugar added

4. Select whole grains

Whole grains are good sources of fiber and other nutrients that play a role in regulating blood pressure and heart health. You can increase the amount of whole grains in a heart-healthy diet by making simple substitutions for refined grain products.

Another easy way to add whole grains to your diet is ground flaxseed. Flaxseeds are small brown seeds that are high in fiber and omega-3 fatty acids, which can lower your total blood cholesterol. You can grind the seeds in a coffee grinder or food processor and stir a teaspoon of them into yogurt, applesauce or hot cereal.

Grain products to choose	Grain products to avoid
Whole-wheat flour Whole-grain bread, preferably 100 percent whole-wheat or 100 percent whole-grain bread High-fiber cereal with 5 or more grams of fiber a serving Whole grains such as brown rice, barley and buckwheat (kasha) Whole-grain pasta Oatmeal (steel-cut or regular) Ground flaxseed	White, refined flour White bread Muffins Frozen waffles Corn bread Doughnuts Biscuits Quick breads Granola bars Cakes Pies Egg noodles Buttered popcorn High-fat snack crackers
