Heart-healthy diet: 8 steps to prevent heart disease
Ready to start your heart-healthy diet? Here are eight tips to get you started.
By Mayo Clinic Staff
Although you might know that 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. Control your portion size
How much you eat is just as important as what you eat. Overloading your plate, taking seconds and eating until you feel stuffed can lead to eating more calories than you should. Portions served in restaurants are often more than anyone needs.
Use a small plate or bowl to help control your portions. Eat larger portions of low-calorie, nutrient-rich foods, such as fruits and vegetables, and smaller portions of high-calorie, high-sodium foods, such as refined, processed or fast foods. This strategy can shape up your diet as well as your heart and waistline.
Keep track of the number of servings you eat. The recommended number of servings per food group may vary depending on the specific diet or guidelines you’re following. A serving size is a specific amount of food, defined by common measurements such as cups, ounces or pieces. For example, one serving of pasta is about 1/3 to 1/2 cup, or about the size of a hockey puck. A serving of meat, fish or chicken is about 2 to 3 ounces, or about the size and thickness of a deck of cards. Judging serving size is a learned skill. You may need to use measuring cups and spoons or a scale until you’re comfortable with your judgment.
2. Eat more vegetables and fruits
Vegetables and fruits are good sources of vitamins and minerals. Vegetables and fruits are also low in calories and rich in dietary fiber. Vegetables and fruits, like other plants or plant-based foods, contain substances that may help prevent cardiovascular disease. Eating more fruits and vegetables may help you cut back on higher calorie 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 ingredients, such as vegetable stir-fry or fresh fruit mixed into salads.

3. 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. Or be adventuresome and try a new whole grain, such as whole-grain farro, quinoa or barley.

4. Limit unhealthy fats
Limiting how much saturated and trans fats you eat is an important step 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 to include in a heart-healthy diet:
|Type of fat||Recommendation|
|Saturated fat||No more than 5 to 6% of your total daily calories, or no more than 11 to 13g of saturated fat if you follow a 2,000-calorie-a-day diet|
You can 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 add less butter, margarine and shortening when cooking and serving.
You can also use low-fat substitutions when possible for a heart-healthy diet. For example, top your baked potato with low-sodium salsa or low-fat yogurt rather than butter, or use sliced whole fruit or low-sugar fruit spread on your toast instead of margarine.
You may also want to check the food labels of some cookies, cakes, frostings, crackers and chips. Some of these — 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 certain fish, avocados, 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.
An easy way to add healthy fat (and fiber) to your diet is ground flaxseed. Flaxseeds are small brown seeds that are high in fiber and omega-3 fatty acids. Some studies have found that flaxseeds may help lower cholesterol in some people, but more research is needed. You can grind the seeds in a coffee grinder or food processor and stir a teaspoon of them into yogurt, applesauce or hot cereal.

5. Choose low-fat protein sources
Lean meat, poultry and fish, low-fat dairy products, and eggs 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 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 plant protein for animal protein — for example, a soy or bean burger for a hamburger — will reduce your fat and cholesterol intake and increase your fiber intake.

6. Reduce the sodium in your food
Eating a lot of sodium can contribute to high blood pressure, a risk factor for cardiovascular disease. Reducing sodium is an important part of a heart-healthy diet. The American Heart Association recommends that:
- Healthy adults have no more than 2,300 milligrams (mg) of sodium a day (about a teaspoon of salt)
- Most adults ideally have no more than 1,500 mg of sodium a day
Although reducing the amount of salt you add to food at the table or while cooking is a good first step, much of the salt you eat comes from canned or processed foods, such as soups, baked goods and frozen dinners. Eating fresh foods and making your own soups and stews can reduce the amount of salt you eat.
If you like the convenience of canned soups and prepared meals, look for ones with reduced sodium. Be wary of foods that claim to be lower in sodium because they are seasoned with sea salt instead of regular table salt — sea salt has the same nutritional value as regular salt.
Another way to reduce the amount of salt you eat is to choose your condiments carefully. Many condiments are available in reduced-sodium versions, and salt substitutes can add flavor to your food with less sodium.

7. Plan ahead: Create daily menus
You know what foods to feature in your heart-healthy diet and which ones to limit. Now it’s time to put your plans into action.
Create daily menus using the six strategies listed above. When selecting foods for each meal and snack, emphasize vegetables, fruits and whole grains. Choose lean protein sources and healthy fats, and limit salty foods. Watch your portion sizes and add variety to your menu choices.
For example, if you have grilled salmon one evening, try a black-bean burger the next night. This helps ensure that you’ll get all of the nutrients your body needs. Variety also makes your meals and snacks more interesting.
8. Allow yourself an occasional treat
Allow yourself an indulgence every now and then. A candy bar or handful of potato chips won’t derail your heart-healthy diet. But don’t let it turn into an excuse for giving up on your healthy-eating plan. If overindulgence is the exception, rather than the rule, you’ll balance things out over the long term. What’s important is that you eat healthy foods most of the time.
Incorporate these eight tips into your life, and you’ll find that heart-healthy eating is both doable and enjoyable. With planning and a few simple substitutions, you can eat with your heart in mind.Jan. 09, 2019
