An Overview of the Mediterranean Diet: What Foods to Eat and Benefits

The Mediterranean diet is a popular eating pattern that emphasizes fruits, vegetables, whole grains, healthy fats, seafood, and dairy products. It is based on the traditional foods eaten by people living in the Mediterranean region—particularly Greece, Italy, France, and Spain—and has been linked to numerous health benefits. In this article, we’ll explore what the Mediterranean diet consists of, its potential health benefits, tips for following it on a budget, and a week-by-week meal plan. We’ll also compare the different versions of the diet from each Mediterranean country.

Definition of the Mediterranean Diet

The Mediterranean diet is an eating pattern that focuses on nutrient-dense, whole foods such as fruits and vegetables, whole grains, healthy fats, and lean proteins. According to the Harvard T.H. Chan School of Public Health, “It is rich in olive oil, fish, nuts, beans, fruits, and vegetables, but low in red meat and other animal fats.” This diet is associated with a lower risk of chronic diseases, such as heart disease and type 2 diabetes, and improved overall health.

Food Groups Included in the Mediterranean Diet

The Mediterranean diet includes a variety of nutrient-dense foods from the following groups:

Fruits and Vegetables

Fruits and vegetables are the foundation of the Mediterranean diet. The American Heart Association recommends consuming at least four to five servings of fruits and vegetables per day. Examples of fruits and vegetables include apples, oranges, carrots, spinach, kale, tomatoes, bell peppers, and squash.

Whole Grains

Whole grains make up an important part of the Mediterranean diet. Examples of whole grains include quinoa, oats, wheat, barley, and brown rice. Aim to consume at least three to four servings of whole grains per day.

Healthy Fats

Healthy fats are an essential part of the Mediterranean diet. These include monounsaturated fatty acids (MUFAs) found in olive oil, nuts, and avocados, and omega-3 fatty acids found in fatty fish such as salmon and tuna. These fats help to reduce inflammation and improve heart health.

Fish and Seafood

Fish and seafood are an important source of protein and healthy fats in the Mediterranean diet. Aim to consume at least two servings of fish per week. Examples of fish and seafood include salmon, trout, shrimp, mussels, and clams.

Dairy Products

Low-fat or nonfat dairy products are an important source of calcium and protein in the Mediterranean diet. Examples of dairy products include milk, yogurt, cheese, and cottage cheese.

Legumes

Legumes are an excellent source of fiber, plant-based proteins, and vitamins and minerals. Examples of legumes include beans, lentils, chickpeas, and split peas.

Potential Health Benefits of Eating a Mediterranean Diet

Numerous studies have suggested that following a Mediterranean diet can provide numerous health benefits, including weight loss, improved cardiovascular health, improved blood sugar levels, lower risk of certain types of cancer, and improved brain health.

Weight Loss Benefits

Eating a Mediterranean diet may help with weight loss. A study published in the British Medical Journal found that people who followed a Mediterranean diet had greater reductions in body mass index (BMI) and waist circumference than those who followed a low-fat diet. Similarly, a study published in the Journal of the American College of Nutrition found that people who followed a Mediterranean diet lost more weight than those who followed a low-fat diet.

Cardiovascular Benefits

The Mediterranean diet has been linked to improved cardiovascular health. A study published in the New England Journal of Medicine found that people who followed a Mediterranean diet supplemented with extra-virgin olive oil had a 30% lower risk of having a major coronary event, such as a heart attack or stroke, compared to those who followed a low-fat diet. Similarly, a study published in the American Journal of Clinical Nutrition found that people who followed a Mediterranean diet had a lower risk of developing hypertension.

Improved Blood Sugar Levels

The Mediterranean diet has been linked to improved blood sugar levels. A study published in the Diabetes Care journal found that people with type 2 diabetes who followed a Mediterranean diet had significantly lower fasting glucose levels compared to those who followed a low-fat diet. Additionally, a study published in the Journal of Nutrition found that people with prediabetes who followed a Mediterranean diet had significantly lower HbA1c levels compared to those who followed a low-fat diet.

Lower Risk of Certain Types of Cancer

Eating a Mediterranean diet may be associated with a lower risk of certain types of cancer. A study published in the Cancer Causes & Control journal found that people who followed a Mediterranean diet had a lower risk of developing colorectal cancer compared to those who did not follow the diet. Similarly, a study published in the Journal of the National Cancer Institute found that people who followed a Mediterranean diet had a lower risk of developing breast cancer.

Brain Health Benefits

Research suggests that following a Mediterranean diet may be beneficial for brain health. A study published in the Neurology journal found that older adults who followed a Mediterranean diet had a lower risk of developing mild cognitive impairment, a condition characterized by memory problems, difficulty concentrating, and confusion. Similarly, a study published in the Annals of Neurology found that people who followed a Mediterranean diet had a slower rate of cognitive decline compared to those who did not follow the diet.

A Guide to Eating a Mediterranean Diet on a Budget

Eating a Mediterranean diet on a budget is possible. Here are some tips to help you save money while still following the diet:

Buy in Bulk
