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, fat and cholesterol than you should.   ........

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 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.

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 couscous, quinoa or barley.

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.

4. Limit unhealthy fats and cholesterol

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.

5. 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 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.

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 Department of Agriculture recommends:

Healthy adults have no more than 2,300 milligrams (mg) of sodium a day (about a teaspoon)
People age 51 or older, African-Americans, and people who have been diagnosed with high blood pressure, diabetes or chronic kidney disease have no more than 1,500 mg of sodium a day

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.

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.
