Mediterranean Diet

According to many experts, and in my personal opinion as well, the Mediterranean diet is one of the healthiest dietary regimens in existence. Although you will frequently see the term "Mediterranean diet", the word diet does a poor job of describing this concept. The Mediterranean diet is envisioned as a lifestyle that yields the greatest benefits when practiced over many years. Guidelines related to the Mediterranean regimen often address topics that are not strictly related to food, but also to mental health and happiness. For instance, it is recommended to share at least one meal a day with family or friends, engage in light physical activity daily, and enjoy the sun whenever possible.

What Is the Mediterranean Diet?

Broadly speaking, the Mediterranean diet is a way of preparing food, selecting ingredients, and consuming them that is characteristic of countries bordering the Mediterranean Sea, such as Greece and Italy. Major interest in this dietary regimen began about sixty years ago when a disproportionately lower incidence of cardiovascular diseases was observed among populations eating this way compared to developed countries, such as the United States and Northern Europe.

There is no strict definition of the ingredients used in the Mediterranean diet because the Mediterranean region includes numerous countries and even more cities where people eat differently. While there are some general rules, this diet is easily adaptable to individual preferences or the region where one lives.

What Does the Mediterranean Diet Include?

It is plant-based rather than meat-based. Red meat is consumed only once or twice a week, and on other days it is replaced by chicken, beans, fish, or other protein-rich foods.

The Mediterranean diet is characterized by a high, daily intake of fruits and vegetables. The emphasis is on minimal heat processing of ingredients to preserve all vitamins, as well as incorporating various colors on the plate to ensure a full spectrum of nutrients. According to some sources, potatoes are not categorized as a favorable vegetable due to their high energy and carbohydrate content.

A major pillar of the Mediterranean diet is replacing bad fats with healthier alternatives. Trans and saturated fats should be avoided and replaced with unsaturated fats. This shift significantly reduces the risk of cardiovascular diseases. The primary source of fat in the Mediterranean dietary regimen is olive oil. Olive oil is rich in unsaturated fats that positively affect good cholesterol levels while simultaneously lowering bad cholesterol. Additionally, omega-3 fatty acids are obtained by consuming fish, which is highly prominent in the Mediterranean diet. Cold-water fish like herring, tuna, and salmon are particularly rich in omega-3 fatty acids.

According to most sources, the intake of whole grains is highly recommended, alongside replacing white flour bread with options of higher nutritional quality. There are no rigid guidelines determining which specific grains are required, so you can choose them according to your taste.

A wide variety of distinct culinary herbs and spices is utilized in Mediterranean cooking. This not only enhances the flavor of food but also delivers health benefits, as most herbs have a soothing or therapeutic effect on certain organs or organ systems. Additionally, utilizing spices reduces the need for table salt, which is considered harmful to heart health.

All highly processed foods are avoided, as well as foods with a high amount of added sugars. This category includes sodas, sweets, snacks, processed meats such as sausages, salami, hot dogs, etc., white flour, and processed fats and oils like margarine and butter.

Eggs, cheeses, yogurts, and other dairy products are not banned, but a lower overall intake is generally recommended. If you want to transition to a Mediterranean style of eating, dairy products with a lower fat percentage are recommended, such as Greek yogurt, while avoiding added sugars like those found in commercial fruit yogurts.

People often find the recommendation to consume red wine to be the most interesting aspect of the Mediterranean diet. Naturally, water should remain the main and primary source of hydration, but a single glass of wine per day is permitted. It is also advised to always enjoy wine in the company of others. Coffee and herbal teas are allowed, but the addition of sweeteners, sugar, and honey should be avoided.

Who Is the Mediterranean Diet For?

Studies have shown that individuals who transition to a Mediterranean dietary regimen experience significant health benefits. These are primarily seen in the prevention of cardiovascular diseases and type 2 diabetes. Further down in the text, we will cover the positive effects of this diet on health and specific conditions in greater detail.

For these reasons, doctors most frequently recommend this dietary regimen to people who already face cardiovascular issues or have a high genetic predisposition to them, as well as individuals dealing with insulin resistance, prediabetes, or type 2 diabetes, since this diet can alleviate symptoms. However, the Mediterranean diet works best as a preventive measure, and since it has no documented negative side effects, it is recommended to anyone who cares about their health.

It has demonstrated solid results in reducing body weight, particularly when paired with increased physical activity and restricted calorie intake. For this reason, it is recommended to individuals struggling with weight management as an effective way to lose weight and maintain it.

Due to the aging population across the modern world, medical treatment costs are rising. The most common conditions are precisely those where a Mediterranean-type diet can help, leading to a growing number of papers addressing the economic benefits and lowered healthcare costs for populations adhering to this regimen.

Although all populations share equal benefits when transitioning to a Mediterranean diet, doing so is not always feasible due to regional, social, and cultural-religious factors. The Mediterranean diet is not cheap, as the majority of the ingredients are of high quality, which influences the price; additionally, fresh fruits and vegetables are not accessible everywhere or at all times of the year. The solution to this issue lies in designing localized dietary regimens that achieve the identical effects using local resources and regional ingredients. An example of this is the DASH diet, which was modeled after the Mediterranean diet but adapted to the American environment.

Why Choose the Mediterranean Diet?

In the opinion of many, the Mediterranean diet is the best and healthiest diet in the world. It was ranked as the best diet overall based on a comprehensive score by U.S. News. Furthermore, in 2013, the Mediterranean diet was inscribed onto the Representative List of the Intangible Cultural Heritage of Humanity by UNESCO.

The guidelines for following the Mediterranean dietary regimen are incredibly simple. Most people do not count calories or track the exact quantity of food consumed; instead, they focus strictly on the type of ingredients and the timing of meals. For this reason, anyone willing to start a healthier lifestyle can embark on this regimen today without much hassle (though most usually start "tomorrow").

While there are numerous recipes aligned with the Mediterranean diet, practically anything you prepare will be good as long as it features minimal meat, sugar, and processed fats, is colorful, and is fundamentally plant-based. With just a little effort, you can quickly learn how to conceptualize and prepare meals that conform to this regimen. Naturally, for any questions or advice, you can always reach out to me.

Health Benefits of the Mediterranean Diet

Over the past 60 years, an enormous volume of research has been conducted evaluating the effects of the Mediterranean dietary regimen on various diseases and conditions. The largest share of research has been carried out in the area of heart disease, but other studies point to improvements across many different conditions.

Cardiovascular Diseases

Cardiovascular diseases are the most common cause of death worldwide, estimated to account for 31% of all fatalities. For this reason, finding a diet that reduces the risk of illness has been a top priority in medical nutrition for more than half a century.

According to one study, the Mediterranean diet reduces the likelihood of complications in cardiovascular diseases by 37%, data that was examined and corroborated by another study. In addition, the results of a vast number of research papers point to potential positive effects of this diet in preventing heart attacks, cardiac arrest, coronary artery disease, and strokes.

Yet another study suggests that if regular physical activity and a smoke-free lifestyle are added to the Mediterranean diet, the predisposition to coronary artery disease drops by more than 80%, while the susceptibility to strokes is reduced by 70%.

The European Society of Cardiology, the American College of Cardiology, and the National Heart Foundation of Australia all endorse the Mediterranean diet as a way to lower the risk of cardiovascular diseases.

Body Weight and BMI

According to data from the World Health Organization, over 4 million people die each year from consequences related to excess body weight. Obesity among children aged 5 to 19 has increased more than fourfold over the last forty years. The World Health Organization warns of obesity reaching epidemic proportions, requiring swift action. One potential solution could be the Mediterranean dietary regimen.

The Mediterranean diet shows expectedly positive results regarding weight loss. The exact driver behind these effects might be a combination of multiple positive aspects of this regimen, such as a low intake of processed fats and simple sugars, a high intake of fiber from fruits and vegetables, and the regulation of the ratio between saturated and unsaturated fats.

The first study that attempted to measure the exact effectiveness of the Mediterranean diet was published in 2011. Synthesizing a large number of previously conducted trials, scientists determined that individuals on this diet lost an average of 1.75 kilograms; however, when a restricted calorie intake was added to the diet, the mean loss increased to 3.88 kilograms, and exceeded 4 kilograms when combined with physical activity. Additionally, they concluded that no weight gain was recorded among those on the Mediterranean dietary regimen.

Another publication points to similar outcomes. Comparing the Mediterranean diet against alternative diets demonstrated significantly better results. Over 12 months, participants on the Mediterranean regimen lost between 4.1 and 10.1 kilograms, a result that is highly comparable to modern structured weight-loss diets.

Cancer

Cancer is the second leading cause of death worldwide, with one in six people passing away from the disease. It represents a large group of diseases that can affect almost any organ or tissue in the body, compromising men and women equally. Risk factors are numerous and varied, but they can be broadly divided into three groups: individual factors, environmental factors, and lifestyle factors. While we generally cannot alter individual and environmental factors, lifestyle factors are entirely modifiable.

Smoking is considered the single greatest risk factor, driving 22% of cancer deaths; however, diet, physical activity, and weight management combined are estimated to influence the avoidance of cancer by 30% to 50%. Depending on the type of cancer, the daily consumption of ingredients like cabbage, broccoli, carrots, etc.—meaning foods rich in vitamins, minerals, and antioxidants—can drastically impact prevention.

The Mediterranean diet contains a large number of ingredients rich in substances that assist in fighting cellular degeneration, which leads to the onset of cancer. Due to the loose definition of the Mediterranean diet, scientists face challenges in isolating its precise efficacy in cancer prevention, but multiple studies have demonstrated a powerful correlation between the Mediterranean diet and a reduced risk of malignancies.

Other Diseases

With varying degrees of data reliability and diverse outcomes, the impact of the Mediterranean dietary regimen is being evaluated against numerous other illnesses. Some of the conditions showing indications of being alleviated or prevented by the Mediterranean diet include: asthma, cognitive decline, metabolic syndrome, rheumatoid arthritis, type 2 diabetes mellitus, and others.

A study conducted in 2018 looked into the underlying causes behind the positive health effects of the Mediterranean diet. They examined metabolic paths and molecular mechanisms, concluding that a Mediterranean-type diet leads to:

• A reduction in lipids and a positive modification of their biological effects
• Anti-inflammatory, antioxidant, and anti-aggregatory effects
• Modulation of cancer-promoting mediators (hormones and growth factors)
• Favorable alterations in gut microbiota

Meal Examples

• Breakfast: Greek yogurt with berries and hazelnuts
• Lunch: Salmon with garlic and honey
• Dinner: Steamed vegetables
• Breakfast: Eggs with spinach and tomatoes
• Lunch: Chicken cooked in olive oil with garlic, olives, and herbs
• Dinner: Whole-wheat pasta paired with a seasonal salad
• Breakfast: Scrambled eggs with zucchini and tomatoes
• Lunch: Seafood soup
• Dinner: Polenta with roasted eggplant, mushrooms, and red bell peppers

Concluding Words

When it comes to the Mediterranean diet, even I previously only knew in general terms that it was recommended for people struggling with heart issues and arthritis, and that it incorporates plenty of culinary herbs. However, once I initially became interested and dove deeper into this topic, I realized that the benefits provided by this dietary regimen are far greater and more significant. The dietary pattern itself should, naturally, be adapted to our local regions by incorporating as many healthy domestic plants as possible—for example, nettle, wild mushrooms, plums, etc.
