Mediterranean Diet: Choose This Heart-Healthy Diet Option

The Mediterranean diet is a heart-healthy eating plan combining elements of Mediterranean-style cooking

by Mayo Clinic Staff

If you’re looking for a heart-healthy eating plan, the Mediterranean diet might be right for you. The Mediterranean diet incorporates the basics of healthy eating — plus a splash of flavorful olive oil and perhaps a glass of red wine — among other components characterizing the traditional cooking style of countries bordering the Mediterranean Sea.

Most healthy diets include fruits, vegetables, fish and whole grains, and limit unhealthy fats. While these parts of a healthy diet remain tried-and-true, subtle variations or differences in proportions of certain foods may make a difference in your risk of heart disease.

Benefits of the Mediterranean diet

Research has shown that the traditional Mediterranean diet reduces the risk of heart disease. In fact, a recent analysis of more than 1.5 million healthy adults demonstrated that following a Mediterranean diet was associated with a reduced risk of overall and cardiovascular mortality, a reduced incidence of cancer and cancer mortality, and a reduced incidence of Parkinson’s and Alzheimer’s diseases.

For this reason, most if not all major scientific organizations encourage healthy adults to adapt a style of eating like that of the Mediterranean diet for prevention of major chronic diseases.

Healthy fats

The focus of the Mediterranean diet isn’t on limiting total fat consumption, but rather to make wise choices about the types of fat you eat. The Mediterranean diet discourages saturated fats and hydrogenated oils (trans fats), both of which contribute to heart disease.

The Mediterranean diet features olive oil as the primary source of fat. Olive oil provides monounsaturated fat — a type of fat that can help reduce LDL cholesterol levels when used in place of saturated or trans fats. “Extra-virgin” and “virgin” olive oils — the least processed forms — also contain the highest levels of the protective plant compounds that provide antioxidant effects.

Monounsaturated fats and polyunsaturated fats, such as canola oil and some nuts, contain the beneficial linolenic acid (a type of omega-3 fatty acid). Omega-3 fatty acids lower triglycerides, decrease blood clotting, are associated with decreased sudden heart attack, improve the health of your blood vessels, and help moderate blood pressure. Fatty fish — such as mackerel, lake trout, herring, sardines, albacore tuna and salmon — are rich sources of omega-3 fatty acids. Fish is eaten on a regular basis in the Mediterranean diet.

Putting it all together

The Mediterranean diet is a delicious and healthy way to eat. Many people who switch to this style of eating say they’ll never eat any other way. Here are some specific steps to get you started:

• Eat your veggies and fruits — and switch to whole grains. An abundance and variety of plant foods should make up the majority of your meals. They should be minimally processed, and try to purchase them when they’re in season. Strive for seven to 10 servings a day of veggies and fruits. Switch to whole-grain bread and cereal, and begin to eat more whole-gain rice and pasta products. Keep baby carrots, apples and bananas on hand for quick, satisfying snacks. Fruit salads are a wonderful way to eat a variety of healthy fruit.
• Go nuts. Keep almonds, cashews, pistachios and walnuts on hand for a quick snack. Choose natural peanut butter, rather than the kind with hydrogenated fat added. Try tahini (blended sesame seeds) as a dip or spread for bread.
• Pass on the butter. Try olive or canola oil as a healthy replacement for butter or margarine. Use it in cooking. After cooking pasta, add a touch of olive oil, some garlic and green onions for flavoring. Dip bread in flavored olive oil or lightly spread it on whole-grain bread for a tasty alternative to butter. Try tahini (blended sesame seeds) as a dip or spread for bread too.
• Spice it up. Herbs and spices make food tasty and are also rich in health-promoting substances. Season your meals with herbs and spices rather than salt.
• Go fish. Eat fish once or twice a week. Fresh or water-packed tuna, salmon, trout, mackerel and herring are healthy choices. Grilled fish tastes good and requires little cleanup. Avoid fried fish, unless it’s sauteed in a small amount of canola oil.
• Rein in the red meat. Substitute fish and poultry for red meat. When eaten, make sure it’s lean and keep portions small (about the size of a deck of cards). Also avoid sausage, bacon and other high-fat meats.
• Choose low-fat dairy. Limit higher fat dairy products such as whole or 2 percent milk, cheese and ice cream. Switch to skim milk, fat-free yogurt and low-fat cheese.
