This way of eating focuses on antioxidant- and anti-inflammatory-rich foods that support long-term health and slow age-related damage. Nutrition experts also share practical advice on how to begin following this diet.
For years, the Mediterranean diet has been associated with better health outcomes. Previous research shows it can support heart health, lower the risk of type 2 diabetes, and may even help protect against certain forms of cancer. New findings now suggest that this eating pattern may also help women live longer.
This conclusion comes from a long-term study published in a major medical journal, where researchers tracked the diets and health markers of 25,315 women over a period of up to 25 years. Along with dietary habits, scientists examined more than 30 biological markers, including cholesterol levels and insulin resistance. Results showed that women who closely followed a Mediterranean-style diet had a 23% lower risk of death from any cause. They also experienced a 20% lower risk of death from heart disease and a 17% lower risk of death from cancer.
According to the researchers, diet quality plays a significant role in long-term health. They noted that consistently choosing nutrient-dense foods over many years may offer meaningful protection against age-related diseases and early mortality.
Below, experts explain why the Mediterranean diet supports healthy aging and how women can realistically adopt it into daily life.
How the Mediterranean diet may support a longer life
It’s important to understand that this research shows an association, not direct proof, that the Mediterranean diet causes longer life. However, nutrition experts say the results make sense given the overall health benefits of this eating pattern.
Experts explain that this diet has been linked to lower rates of high blood pressure, type 2 diabetes, metabolic disorders, cardiovascular disease, and certain cancers. All of these conditions are known contributors to illness and early death, particularly as people age.
One major reason the Mediterranean diet is so beneficial is its high antioxidant content. Fruits, vegetables, nuts, and seeds provide vitamins, plant compounds, and protective nutrients that help neutralize free radicals in the body. By reducing oxidative stress, these foods help protect cells and DNA from damage that can accelerate aging and disease development.
The diet also includes natural anti-inflammatory foods, such as fatty fish rich in omega-3 fats and olive oil containing plant polyphenols. Chronic inflammation is linked to heart disease, cancer, and other serious conditions, and reducing it may significantly improve long-term health outcomes.
Fiber is another key component of this eating pattern. Foods like legumes, whole grains, fruits, and vegetables support digestive health, help regulate blood sugar, and may reduce the risk of colorectal cancer. Fiber also promotes fullness, which can support healthy weight management over time.
Healthy fats are emphasized as well, particularly those from olive oil, nuts, and fish. These fats help raise good cholesterol levels while lowering harmful cholesterol, reducing strain on the heart and blood vessels.
Finally, the Mediterranean diet limits ultra-processed foods, which are often high in added sugars, unhealthy fats, and artificial ingredients. Reducing these foods can help lower the risk of obesity, heart disease, and certain cancers.
What foods are included in the Mediterranean diet
Although it’s widely discussed, many people aren’t completely sure what the Mediterranean diet actually includes. At its core, the focus is on fresh, minimally processed foods.
This eating pattern encourages frequent consumption of:
- Fruits and vegetables
- eafood
- Olive oil
- Nuts and seeds
- Beans and legumes
- Whole grains
- Fresh herbs and spices
These foods are allowed in moderate amounts:
- Poultry
- Milk, yogurt, and cheese
- Red wine in small quantities
The diet recommends limiting:
- Refined grains and processed oils
- Red meat and processed meats
- Packaged and ultra-processed foods
- Sugary desserts and candies
How to start following the Mediterranean diet
Switching to a new way of eating doesn’t have to happen overnight. Nutrition professionals recommend making small, manageable changes.
A simple way to begin is by adding more foods rather than focusing on restrictions. For example, include fruit with breakfast, choose whole-grain bread for lunch, and fill half your dinner plate with vegetables. Trying new seafood dishes and adding more beans or lentils to meals can also help ease the transition.
This diet is highly flexible and adaptable. There is a wide range of fruits, vegetables, grains, seafood, and plant-based proteins to choose from, along with modest portions of poultry, eggs, and dairy. Once comfortable, aim to include at least one to two servings of produce with every meal and use fruit as a regular snack or dessert.
Gradually replacing refined grains with whole grains and swapping meat-based meals for plant-based options can further strengthen the diet. Eating fish, such as salmon, twice a week and using olive oil instead of butter for cooking are additional steps that support heart and metabolic health.
For those who want personalized guidance, working with a registered dietitian can help tailor the Mediterranean diet to individual preferences and health goals. Many cookbooks and recipe collections are also available to provide meal ideas for breakfast, lunch, and dinner.
