The Mediterranean diet is more than just a way of eating. It is a lifestyle that has been proven to offer numerous health benefits, from preventing chronic diseases to enhancing longevity. In this article, you will learn what the Mediterranean diet is, how it originated, and what are some of the most compelling reasons to adopt it.
What is the Mediterranean diet?
The Mediterranean diet is a style of eating that emphasizes minimally processed, plant-based foods. It includes fruits, vegetables, nuts, beans, whole grains, olive oil, and moderate amounts of fish, eggs, dairy, and meat. The Mediterranean diet also encourages the consumption of red wine in moderation, usually with meals.
The Mediterranean diet is not a rigid or strict regimen. Rather, it is a flexible and adaptable pattern that can vary depending on the region, culture, and personal preferences of the people who follow it. However, the common elements of the Mediterranean diet are:
- Plenty of vegetables and fruits, which provide vitamins, minerals, antioxidants, and fiber
- Whole grains, such as whole-wheat bread, pasta, couscous, bulgur, and oats, which provide complex carbohydrates, fiber, and phytochemicals
- Legumes, such as beans, lentils, chickpeas, and peas, which provide protein, fiber, and phytochemicals
- Nuts and seeds, such as almonds, walnuts, pistachios, sunflower seeds, and sesame seeds, which provide healthy fats, protein, fiber, and phytochemicals
- Olive oil, which is the main source of fat in the Mediterranean diet, and which provides monounsaturated fatty acids, antioxidants, and anti-inflammatory compounds
- Fish and seafood, which provide high-quality protein, omega-3 fatty acids, and other nutrients
- Eggs and dairy, which provide high-quality protein, calcium, and other nutrients
- Meat and poultry, which provide high-quality protein, iron, and other nutrients, but are consumed in smaller portions and less frequently than in other diets
- Red wine, which contains polyphenols, antioxidants, and other beneficial compounds, but is consumed in moderation and with meals
- Herbs and spices, such as basil, oregano, rosemary, thyme, garlic, onion, and pepper, which add flavor and aroma to the dishes, and which have antioxidant and anti-inflammatory properties
The Mediterranean diet also emphasizes the importance of enjoying food with family and friends, being physically active, and having a balanced and positive attitude towards life.
How did the Mediterranean diet originate?
The Mediterranean diet is inspired by the traditional eating habits and food culture of the people living in the countries bordering the Mediterranean Sea, especially the olive-growing regions of Southern Italy, Greece, and Crete. The Mediterranean diet as we know it today was first publicized in 1975 by the American biologist Ancel Keys and his wife, chemist Margaret Keys, who studied the dietary patterns and health outcomes of different populations around the world. They found that the people living in the Mediterranean regions had lower rates of heart disease, stroke, and other chronic diseases, and longer life expectancy, than the people living in other countries, such as the United States, Finland, and Japan. They attributed this to their diet, which was rich in plant foods, olive oil, fish, and wine, and low in animal fats, refined carbohydrates, and processed foods1
Since then, numerous studies have confirmed and expanded the findings of the Keys, and have shown that the Mediterranean diet is associated with a variety of health benefits, not only for the heart, but also for the brain, the gut, the bones, the skin, and the overall well-being.
What are the benefits of the Mediterranean diet?
The Mediterranean diet has been extensively researched and has been shown to offer many advantages for your health and well-being. Here are some of the most amazing benefits of following this lifestyle:
1. It lowers your risk of heart disease and stroke
One of the most well-known and well-established benefits of the Mediterranean diet is its protective effect on the cardiovascular system. The Mediterranean diet can lower your blood pressure, cholesterol, triglycerides, and inflammation, which are all risk factors for heart disease and stroke. The Mediterranean diet can also improve your blood vessel function, prevent blood clots, and reduce oxidative stress, which are all beneficial for your heart health23
Several studies have demonstrated that the Mediterranean diet can reduce the incidence and mortality of cardiovascular events, such as heart attacks and strokes, in different populations and settings. For example, a large randomized trial called PREDIMED, which involved more than 7,000 people at high risk of cardiovascular disease, found that those who followed a Mediterranean diet supplemented with either extra virgin olive oil or nuts had a 30% lower risk of having a major cardiovascular event, compared to those who followed a low-fat diet4
Another study, called the Lyon Diet Heart Study, which involved more than 600 people who had survived a heart attack, found that those who followed a Mediterranean diet had a 50% to 70% lower risk of having a recurrent heart attack, compared to those who followed a Western-style diet5
2. It may prevent or delay cognitive decline and dementia
Another remarkable benefit of the Mediterranean diet is its positive impact on the brain and cognitive function. The Mediterranean diet can nourish your brain with essential nutrients, such as omega-3 fatty acids, antioxidants, and anti-inflammatory compounds, which can protect your brain cells from damage and aging. The Mediterranean diet can also improve your blood flow to the brain, which can enhance your cognitive performance and memory67
Several studies have suggested that the Mediterranean diet can prevent or delay cognitive decline and dementia, especially Alzheimer’s disease, in older adults. For example, a study that followed more than 1,600 people for an average of five years found that those who adhered to the Mediterranean diet had a 34% lower risk of developing Alzheimer’s disease, compared to those who did not8
Another study that followed more than 2,000 people for an average of four years found that those who adhered to the Mediterranean diet had a 28% lower risk of developing mild cognitive impairment, a condition that often precedes dementia, compared to those who did not. Moreover, those who had mild cognitive impairment and adhered to the Mediterranean diet had a 48% lower risk of progressing to Alzheimer’s disease, compared to those who did not9
3. It may help you lose weight and maintain a healthy weight
The Mediterranean diet can also help you lose weight and maintain a healthy weight, which can have many benefits for your health and well-being. The Mediterranean diet can help you control your appetite, regulate your blood sugar, and boost your metabolism, which can all facilitate weight loss and prevent weight regain. The Mediterranean diet can also improve your body composition, by increasing your muscle mass and decreasing your fat mass, especially your abdominal fat, which is linked to many health problems.
Several studies have shown that the Mediterranean diet can be effective for weight loss and weight management, in different populations and settings. For example, a meta-analysis of 21 randomized trials, which involved more than 3,000 people, found that those who followed a Mediterranean diet lost more weight and had greater reductions in their body mass index, waist circumference, and body fat percentage, compared to those who followed other diets, such as low-fat, low-carb, or high-protein diets.
Another study, which involved more than 800 people with overweight or obesity, found that those who followed a Mediterranean diet had greater weight loss and improvements in their cardiometabolic risk factors, such as blood pressure, cholesterol, and insulin sensitivity, compared to those who followed a low-fat diet, after one and two years of follow-up.
4. It may reduce your risk of certain types of cancer
The Mediterranean diet may also reduce your risk of certain types of cancer, by providing you with antioxidants, anti-inflammatory compounds, and phytochemicals, which can modulate your immune system, inhibit tumor growth, and prevent DNA damage. The Mediterranean diet may also lower your exposure to carcinogens, such as nitrosamines, heterocyclic amines, and polycyclic aromatic hydrocarbons, which are formed when meat is cooked at high temperatures or smoked.
Several studies have indicated that the Mediterranean diet may lower the risk of various cancers, such as breast, colorectal, prostate, gastric, liver, and pancreatic cancer, in different populations and settings. For example, a meta-analysis of 83 studies, which involved more than 2 million people, found that those who adhered to the Mediterranean diet had a 13% lower risk of developing cancer overall, and a 17% lower risk of developing colorectal cancer, compared to those who did not.
Another study, which involved more than 4,000 women, found that those who followed a Mediterranean diet supplemented with extra virgin olive oil had a 68% lower risk of developing breast cancer, compared to those who followed a low-fat diet.
5. It may protect your bones and joints
The Mediterranean diet may also protect your bones and joints, by providing you with calcium, vitamin D, magnesium, and other nutrients that are essential for bone health. The Mediterranean diet may also prevent bone loss, by reducing inflammation, oxidative stress, and hormonal imbalances, which can all contribute to osteoporosis and fractures. The Mediterranean diet may also prevent joint damage, by reducing inflammation, oxidative stress, and autoimmunity, which can all cause arthritis and rheumatic diseases.
Several studies have suggested that the Mediterranean diet may improve bone density and quality, and reduce the risk of fractures, in older adults. For example, a study that followed more than 1,000 people for an average of six years found that those who adhered to the Mediterranean diet had a 25% lower risk of hip fractures, compared to those who did not.
Another study, which involved more than 200 people with rheumatoid arthritis, found that those who followed a Mediterranean diet had less pain, stiffness, and inflammation, and better physical function, compared to those who followed a control diet.
6. It may support your gut health and immunity
The Mediterranean diet may also support your gut health and immunity, by providing you with prebiotics, probiotics, and fiber, which can nourish your gut microbiome and enhance its diversity and function. The gut microbiome is a complex community of bacteria, fungi, viruses, and other microorganisms that live in your digestive tract, and that play a vital role in your digestion, metabolism, immunity, and mood. The Mediterranean diet may also modulate your immune system, by reducing inflammation, oxidative stress, and autoimmunity, which can all impair your immune response and increase your susceptibility to infections and diseases.
Several studies have shown that the Mediterranean diet can improve the composition and activity of the gut microbiome, and increase the production of beneficial metabolites, such as short-chain fatty acids, which can have anti-inflammatory, anti-cancer, and anti-obesity effects. For example, a study that involved more than 600 people found that those who followed a Mediterranean diet had higher levels of beneficial bacteria, such as Bifidobacterium and Lactobacillus, and lower levels of harmful bacteria, such as Clostridium and Enterobacteriaceae, compared to those who followed a Western-style diet.
Another study, which involved more than 300 people, found that those who followed a Mediterranean diet had higher levels of short-chain fatty acids, such as butyrate and propionate, and lower levels of inflammatory markers, such as interleukin-6 and C-reactive protein, compared to those who followed a control diet.
7. It may enhance your mood and mental health
The Mediterranean diet may also enhance your mood and mental health, by providing you with nutrients, such as omega-3 fatty acids, antioxidants, and B vitamins, which can support your brain function and neurotransmitter production. The Mediterranean diet may also improve your blood flow to the brain, which can enhance your cognitive performance and emotional regulation. The Mediterranean diet may also reduce your stress levels, by promoting a positive and relaxed attitude towards life, and by encouraging social interaction and support.
Several studies have indicated that the Mediterranean diet can improve the symptoms and outcomes of various mental disorders, such as depression, anxiety, bipolar disorder, and schizophrenia, in different populations and settings. For example, a meta-analysis of 21 studies, which involved more than 117,000 people, found that those who adhered to the Mediterranean diet had a 33% lower risk of developing depression, compared to those who did not.
Another study, which involved more than 15,000 people, found that those who followed a Mediterranean diet had lower levels of anxiety, and higher levels of happiness, optimism, and self-esteem, compared to those who followed a Western-style diet.
Conclusion
The Mediterranean diet is a style of eating that emphasizes minimally processed, plant-based foods, olive oil, fish, and wine, and that also values physical activity, social interaction, and enjoyment of life. The Mediterranean diet has been proven to offer numerous health benefits, such as lowering your risk of heart disease and stroke, preventing or delaying cognitive decline and dementia, helping you lose weight and maintain a healthy weight, reducing your risk of certain types of cancer, protecting your bones and joints, supporting your gut health and immunity, and enhancing your mood and mental health. The Mediterranean diet is not only good for your body, but also for your mind and soul.
