The Mediterranean diet is an eating pattern based on the traditional foods of countries bordering the Mediterranean Sea. It emphasizes olive oil, fruits, vegetables, whole grains, legumes, nuts, seeds, and fish, and may help lower the risk of heart disease, type 2 diabetes, and some chronic diseases.
Unlike restrictive diets, the Mediterranean diet encourages long-term eating habits rather than calorie counting. It may also support weight management, healthy blood sugar levels, brain function, and reduced inflammation through a variety of nutrient-rich foods.
Following the Mediterranean diet involves choosing mostly fresh, minimally processed foods while limiting highly processed products and added sugars. A balanced meal plan centered on these foods can make the diet easier to follow while supporting long-term health.
Main benefits
The main benefits of the Mediterranean diet include:
1. Reduces the risk of cardiovascular disease
The Mediterranean diet includes foods such as olive oil, fish, nuts, fruits, and vegetables. These foods provide polyunsaturated fats, vitamin E, fiber, and antioxidants that may help reduce inflammation and improve blood circulation.
According to the American Heart Association, a Mediterranean-style diet may help prevent heart disease and stroke by improving cardiovascular risk factors such as cholesterol levels, blood pressure, diabetes, and obesity.
2. Reduces the risk of cancer
The Mediterranean diet is rich in fruits and vegetables, which provide a wide range of antioxidants.
Some studies suggest that the Mediterranean diet may lower the risk of certain cancers, including stomach, esophageal, breast, and ovarian cancer.
3. Supports weight loss
The Mediterranean diet prioritizes natural, fresh foods that are high in fiber, healthy fats, and antioxidants. These foods can increase fullness, reduce calorie intake, and support weight loss.
The diet also limits packaged and highly processed foods, which are often high in fat, sodium, and added sugar. Reducing these foods can also help with weight management.
4. Helps control blood sugar
High-fiber foods, including vegetables, fruits, legumes, and nuts, are an important part of the Mediterranean diet. According to the CDC, fiber-rich foods can support blood sugar management in people with diabetes.
The antioxidants in this diet may also support the function of organs such as the pancreas, which produces insulin.
5. Improves cognitive function
The high antioxidant content of the Mediterranean diet helps protect nerve cells from oxidative stress and damage. This may help preserve cognitive function over time.
The diet may also help prevent memory loss and reduce the risk of neurodegenerative conditions such as Parkinson’s disease, Alzheimer’s disease, and dementia.
6. May ease rheumatoid arthritis symptoms
The Mediterranean diet is rich in omega-3 fatty acids, which have anti-inflammatory properties. These fats may help reduce joint stiffness and pain caused by inflammatory conditions such as rheumatoid arthritis.
How to follow
To follow the Mediterranean diet, make the following changes to your eating habits:
1. Avoid highly processed foods
Most meals should consist of natural foods, particularly plant-based foods such as brown rice, soybeans, and vegetables. Natural animal-based foods, including eggs and milk, may also be eaten in moderation.
It is also recommended to replace ready-made foods, such as packaged cookies and cakes, with homemade versions.
Reducing highly processed foods may help lower inflammation and fluid retention, which can reduce bloating.
2. Eat fish and seafood
Fish or seafood should be eaten at least three times per week. These foods are good sources of protein and healthy fats, including omega-3 fatty acids.
Omega-3 fatty acids have anti-inflammatory properties and may help relieve joint pain, improve blood circulation, and reduce the risk of heart disease.
3. Use olive oil and other healthy fats
Olive oil and vegetable oils, such as canola oil and flaxseed oil, contain heart-healthy fats. These fats may help control cholesterol and reduce the risk of cardiovascular disease.
To obtain these benefits, add olive oil to food after it has been prepared and consume no more than two tablespoons per day. Olive oil can also be used for cooking, sautéing, and grilling meat or fish.
Sunflower oil is rarely used in the Mediterranean diet.
4. Choose whole-grain foods
The Mediterranean diet includes whole-grain foods such as brown rice, whole-wheat flour, oats, and whole-wheat pasta. These foods provide fiber, vitamins, and minerals that support normal body function, relieve constipation, and reduce the absorption of sugar and fat in the intestines.
The diet should also include protein-rich plant foods such as beans, soybeans, chickpeas, pumpkin seeds, and flaxseeds. These foods can help strengthen muscles and support metabolism.
5. Eat fruits and vegetables
Increasing fruit and vegetable intake is an important part of the Mediterranean diet. These foods provide fiber, vitamins, and minerals that support metabolism and increase fullness, which may help with weight loss.
It is recommended to eat at least three different fruits per day. One way to do this is to eat a piece of fruit with or after breakfast, lunch, a snack, or dinner.
6. Choose skim milk and low-fat dairy products
To improve the nutritional quality of the diet and reduce fat intake, choose skim milk, plain yogurt, and fresh cheeses such as ricotta and cottage cheese. Low-fat versions of these products may also be used.
To slightly sweeten plain yogurt, add ½ teaspoon of honey or homemade fruit preserves.
7. Include different protein sources
Choose lean cuts of red meat with no visible fat and limit red meat to once per week.
Other meals can include eggs, fish, and combinations of grains and legumes that provide protein. Examples include rice and beans, rice and lentils, or rice and peas.
8. Choose healthy drinks
Water is the best beverage for relieving thirst and drinking with meals. Flavored water can also be prepared by adding lemon or slices of ginger.
The Mediterranean diet may also include one glass of wine per day, equal to about 6 fl oz or 180 mL, especially after dinner. Wine contains polyphenols such as resveratrol, an antioxidant compound that may help support blood vessel health.
