5 Health Benefits Of The Mediterranean Diet, Plus A 7-Day Meal Plan

If you've been keeping up at all with health-related news in the past decade, you've likely heard some pretty reputable experts recommend the Mediterranean diet.

In fact, for the fifth year in a row, the U.S. News & World Report's annual ranking revealed that the Mediterranean diet continues to be named the best overall diet, concluding that it may offer a host of health benefits, including weight loss, heart and brain health, cancer prevention, and diabetes prevention and control.

But how exactly do you follow a Mediterranean diet, and what makes it so adored by nutrition experts?

It became a phenomenon around the world when, in the 1950s and '60s, Ancel Keys and his colleagues studied the diets and overall health of seven countries (United States, the Netherlands, Finland, Yugoslavia, Italy, Greece, and Japan) in relation to coronary heart disease risk.

They found that people in Italy and Greece had the lowest risk of developing coronary heart disease, partially due to their diet.

So what exactly does the Mediterranean diet look like? Unlike diets like paleo and keto, it does not limit macros or calories or cut out any particular food groups (such as grains).

Instead, it focuses more on a healthy pattern of eating real, whole foods within every food group—possibly making you less likely to feel restricted and more likely to stick to it.

A typical, balanced Mediterranean diet includes antioxidant-rich fruits, vegetables, whole grains, beans, legumes, nuts, seeds, olive oil, herbs, and spices.

It also promotes regular consumption of omega-3-rich fish and seafood and weekly consumption of poultry, eggs, cheese, and yogurt.

The diet limits red meat, sweets, and other processed foods. Red wine is encouraged in moderation, but it's not a must. Coffee and tea are also allowed, but focus on drinking lots and lots of water.

"It's usually the diet I recommend for my diabetic, heart disease, and autoimmune patients who do not have any food allergies or intolerances," Bindiya Gandhi, M.D., an American Board Family Medicine–certified physician, told mbg.

The Mediterranean diet has long been praised for its wide-ranging health benefits, from improved heart health to a reduced risk of cancer. It's also one of the most studied diets.

The Mediterranean diet is widely promoted due to its positive impact on heart health.

The landmark 2013 PREDIMED study1, which followed over 7,000 people, found that people eating a Mediterranean style diet rich in olive oil and nuts had significantly lower risk of experiencing a major cardiovascular event such as a heart attack or stroke. These people also had fewer cardiovascular disease risk factors such as central obesity.

Healthy fats—like those found in nuts, olive oil, and fatty fish—are likely a key element of the Mediterranean diet's heart-health benefits.

Omega-3 fats, for instance, lower "bad" LDL cholesterol, raise "good" HDL cholesterol, reduce inflammation, and improve insulin resistance.

High levels of fiber and antioxidants from a variety of vegetables, fruits, and red wine have cardioprotective effects as well.

The Mediterranean diet's focus on real, whole foods—particularly those that are high in fiber—makes it a great choice for anyone looking to improve their overall metabolic health.

"A high-fiber diet improves diabetes and glucose intolerance, keeps you full, and makes you less likely to gain weight," says Gandhi.

The Mediterranean diet contains naturally high levels of antioxidants from a variety of colorful plant foods.

Antioxidants are compounds that help stop or slow oxidative damage and reduce inflammation throughout the body—which is why they're often associated with a reduced risk of cancer6 and neurodegenerative diseases7.

In fact, studies show that the Mediterranean diet has a protective effect against various types of cancers.

For many of the same reasons that the Mediterranean diet is great for cancer prevention (i.e., its antioxidant and anti-inflammatory properties), it's also great for brain health.

Research has shown that the Mediterranean diet may delay or reduce the risk of Alzheimer's9 disease, as well as depression10.

The high intake of whole grains, fruits, and vegetables means this diet is also high in fiber, vitamins, minerals, and antioxidants—all of which can benefit gut health by feeding the beneficial probiotic bacteria that live there, as well as reducing inflammation.

In one study12, primates that were fed a plant-heavy Mediterranean diet had a significantly higher population of good gut bacteria than those eating a typical meat-focused Western diet.

The main idea of the Mediterranean diet is to eat real, whole foods and to largely avoid processed foods.

In general, you want to try to base your meals around fruits and vegetables (aim for about nine servings a day), whole grains, beans, nuts, and legumes.

Add in some healthy fats such as omega-3-rich fish and olive oil. And, if you're in the mood for meat, stick to lean meats such as chicken and turkey.

Remember, the Mediterranean diet is not a diet of exclusion, it's a general eating pattern focusing on nutrient-rich whole foods.
