The health benefits of Mediterranean diet

The Mediterranean diet, with its emphasis on fresh vegetables and fruit, whole grains, legumes, olive oil and fish, provides an array of health benefits, research suggests.

These include weight loss and a lowered risk of heart disease, diabetes and some cancers. Plus, it’s easy to follow because it allows for a variety of flavorful foods and doesn’t require calorie counting. Find out if it’s right for you.

What Is the Mediterranean Diet?

You’ve probably heard the Mediterranean diet is a healthy way of eating. But did you know it’s been around for decades? Ancel Keys, Ph.D., an American researcher, discovered in the 1950s that foods eaten by people who lived in regions around the Mediterranean, namely southern Italy and Greece, protected them against heart disease.

Over the years, registered dietitians and food writers have formulated this diet into a practical and popular way of eating. The American Heart Association and Dietary Guidelines for Americans (2020-2025) have endorsed the Mediterranean diet as a way of eating that can help reduce risk of heart disease and stroke, as well as a slew of other health ailments.

This diet emphasizes the importance of eating fresh vegetables, fruits, nuts, legumes and whole grains, as well as extra-virgin olive oil and fish. It also encourages the limiting of red meat, processed foods and sweets.

The Mediterranean diet remains a popular way of eating because it’s easy to follow and successfully contributes to optimal health and longevity. In fact, the Mediterranean diet “may help prevent weight gain, type 2 diabetes, heart disease, and certain cancers, as well as preserve cognitive function with age and promote gut health, among other benefits,” says Boston-based registered dietitian Elizabeth Ward, coauthor of The Menopause Diet Plan: A Natural Guide to Managing Hormones, Health and Happiness and former spokesperson for the Academy of Nutrition and Dietetics.

The Mediterranean diet food list

Luckily, Mediterranean diet foods aren’t unusual or hard to find, but they are fresh. “Because it’s based on fresh and lightly processed plant foods, the Mediterranean diet is rich in fiber, vitamins, minerals and phytonutrients, which are protective plant compounds,” says Ward. Below is a list of Mediterranean diet-approved foods and how they can benefit your health.

Vegetables and fruit

Eating plenty of vegetables can help prevent cardiovascular disease, according to a 2017 article in the journal Nutrients. And a diet that relies on vegetables and fruit can prevent some cancers, according to a study published in the Journal of the American Dietetic Association.

Legumes and whole grains

Legumes (or all kinds of beans, including lentils) help regulate blood sugar and may have anti-cancer effects. They also provide protein, fiber, B vitamins, iron and other nutrients. Meanwhile, whole grains are also rich in fiber and contain minerals and phytochemicals, and lower the risk of heart disease, diabetes and cancer.

Olive oil and nuts

The Mediterranean diet relies heavily on extra-virgin olive oil, an unsaturated fat source proven to help lower the chance of stroke and heart attack and reduce blood pressure.

Nuts are nutrient powerhouses, packed with unsaturated fat, protein, fiber and B vitamins. Most nuts contain magnesium, which helps support healthy blood pressure and blood sugar and keeps bones strong, among other benefits. And walnuts specifically contain alpha-linoleic acid, an important omega-3 fatty acid that might reduce risk of coronary heart disease.

Fish

The Mediterranean diet prioritizes fish over other meat sources. “Fish provide high-quality protein, omega-3 fatty acids that promote heart and brain health and help fight chronic inflammation, and several vitamins and minerals, including vitamin D and selenium,” Ward says. “Coldwater fish, such as salmon, have more [healthy] fats than warmer-water fish, but all seafood offers some omega-3s.”

Meanwhile, the Mediterranean diet encourages the consumption of dairy products such as eggs, cheese and yogurt in moderation. These provide calcium, phosphorus, vitamins A and D, protein and saturated fat.

Measuring portions isn’t necessary with this diet, but moderation is key. “It’s important to remember that the eating pattern matters most, and no single food used in the Mediterranean diet, such as olive oil, is a magic bullet for better health,” explains Ward. “For example, you can’t slather as much olive oil as you want on your foods or eat as much feta cheese or nuts as you like.”

Sweets and meat on rare occasions

Eat sweets and meat sparingly on the Mediterranean diet. Avoid junk food, or packaged foods that contain added sugar, saturated fat or salt but few nutrients.

Benefits of the Mediterranean diet

Evidence suggests the Mediterranean diet can reduce risk of premature death from all causes in both men and women. Here are some of the specifics:

Reduces obesity and type 2 diabetes

Eating a Mediterranean diet can help reduce obesity and Type 2 diabetes, both of which can lead to heart disease and stroke, among other health problems. A review of five studies found that overweight or obese people who followed the Mediterranean lost similar or more amounts of weight than those on low-carb, low-fat or other diets.

Lowers risk of stroke and coronary heart disease in women

Results of a 20-year follow up of the Nurses Study (a large continuous study of thousands of nurses designed to identify risk factors for chronic illness) revealed that women who adhered to the Mediterranean diet had a lower risk of coronary heart disease and stroke than those who did not.

Improves gut health

A European study of older adults found that those who followed the Mediterranean diet for a year improved their gut health, which can lead to healthier aging, improved cognition and reduced frailty.

Lowers risk of dementia and cognitive decline

The Mediterranean diet is associated with lower risk of dementia and cognitive impairment.

May reduce the risk of common cancers

Colorectal cancer is the third most common cancer worldwide among men and the second most common cancer among women. Studies show that adhering to the Mediterranean way of eating may reduce the risk of colorectal , breast and prostate cancer.

Reduces high blood pressure

High blood pressure is a condition associated with heart disease and stroke. Following the Mediterranean diet can reduce high blood pressure, thus reducing those serious health risks.
