Benefits of the Mediterranean Diet, Per Experts

Do you eat to live or live to eat? Regardless of which group you consider yourself part of, at a certain point in life, we all start shifting closer to that “eating to live” mindset—a long life, that is. And the Mediterranean diet is one of the best eating styles for longevity and healthy aging.

Research links this style of eating with a host of benefits, such as better brain health and a lower risk of heart disease, some cancers, and type 2 diabetes. The Mediterranean diet features plenty of fruits and vegetables, an emphasis on lean proteins like poultry and fish, healthy fats from olive oil and avocado, nuts and seeds, and plant-based proteins like beans and lentils.

Here, experts break down the benefits of the Mediterranean diet and some of the top foods to fill your plate with.

Unlike many fad diets, there’s an abundance of legit research to back up the potential benefits of the Mediterranean diet, which include:

A Stronger Heart

One large analysis of more than 10,000 people found that there was a “statistically significant reduction” in heart incidents like heart attack, stroke, and heart failure in people who followed a Mediterranean diet compared to those who didn’t.

Researchers attribute these positive outcomes to the abundance of heart-healthy nutrients found in the diet’s whole foods, like antioxidants from fresh fruits and veggies, fiber found in whole grains, and healthy unsaturated fats packed in fish, nuts, and olive oil.

Reduced Risk for Some Cancers

One large review noted that older adults who followed the Mediterranean diet had a lower risk of cancer compared to those who didn’t. Another recent study found that the Mediterranean diet may help lower the risk of cancer in people with obesity.

Healthy Weight Maintenance

A 2023 analysis of several clinical trials found that people with overweight and obesity were more likely to lose body weight on the Mediterranean diet compared to other diets. People who closely followed the Mediterranean diet also had a lower risk of obesity and gaining weight over time.

Diabetes Prevention

One 2025 scientific analysis of nearly 5,000 adults with metabolic syndrome found that those who followed the Mediterranean diet, along with exercising regularly and reducing their calories, were less likely to develop type 2 diabetes than those in other groups. Researchers think that the high intake of polyphenols (a.k.a. plant compounds that act as antioxidants) from fruits, vegetables, whole grains, and nuts may help improve insulin sensitivity, thereby reducing the risk of type 2 diabetes.

Better Brain Health

Scientists also surmise that polyphenols may be beneficial for brain health and mental health conditions like depression and stress. In addition to regular exercise, quitting smoking, and maintaining a healthy weight, the World Health Organization also specifically recommends following a Mediterranean diet to decrease your risk of developing dementia.

Sturdier Bones

A recent study published in JAMA Network Open found that overweight or obese women who followed a Mediterranean diet and regularly exercised by walking for at least 45 minutes a day had stronger bones than those who didn’t follow a Mediterranean style of eating and didn’t walk regularly at the end of the study period.

Healthy Aging

A 30-year study published in the journal Nature Medicine analyzed the impact of diet in midlife on healthy aging, specifically looking at dietary patterns and risk of reaching age 70 without developing any major chronic diseases.

For the study, researchers looked at data from the Nurses’ Health Study and the Health Professionals Follow-Up Study, and zeroed in on the dietary habits of 105,000 adults aged 39 to 69. After analyzing the data, the researchers found that 9.3% of the participants aged in a healthy way, which means they met several cognitive, physical, and mental health metrics. These people were more likely to eat diets that were higher in plant foods, like the Mediterranean diet, the researchers discovered.

The Mediterranean diet is about the foods you should eat, rather than foods you should restrict. There aren’t any major rules about counting calories, sugar intake, or macros. It simply encourages enjoying a variety of whole foods in moderation.
