Mediterranean Diet: A Pathway to Health and Wellness

As someone with Italian roots, my deep passion for both food and health naturally led me to pursue a career as a nutritionist and dietitian. Growing up with a Mediterranean diet was more than just a way of eating – it was a way of life. Now, I'm excited to share the incredible benefits of this diet with you. Let's explore the wonderful world of the Mediterranean diet together.

In a world where fad diets come and go, the Mediterranean diet stands as a timeless example of balanced nutrition and general well-being. Rooted in the culinary traditions of countries bordering the Mediterranean Sea, this diet has garnered widespread attention for its numerous health benefits and well-researched scientific support. This review delves into the specifics of the Mediterranean diet, its components, benefits, and the scientific studies supporting its positive effects on health.

The Mediterranean diet emerged from the wisdom of long-living adults. It has been recognized by UNESCO as an Intangible Cultural Heritage of Humanity, highlighting its role in sustaining and enriching the cultural fabric of communities across Cyprus, Croatia, Spain, Greece, Italy, Morocco, and Portugal. This recognition emphasizes the diet's role in shaping the essence of these regions.

Understanding the Mediterranean Diet:

The Mediterranean diet encompasses a variety of dietary traditions practised in countries bordering the Mediterranean Sea. While there are slight variations across regions, the common thread lies in emphasising whole, natural foods. In 1993, was introduced as a guide, highlighting the foods prevalent in the dietary traditions of Crete, Greece, and southern Italy during the mid-20th century. This eating pattern is rich in fruits, vegetables, beans, nuts, whole grains, fish, olive oil, and moderate wine consumption. Physical activity and communal meals are also central components.

How the Mediterranean Diet Operates:

Central to the Mediterranean diet is the practice of eating together. This act of communal dining goes beyond nourishment; it serves as a foundation for cultural identity and continuity. Meals become moments of social exchange, where families, groups, or communities affirm and renew their bonds. The act of sharing food becomes a symbol of fostering intercultural dialogue and unity.

The Mediterranean diet promotes daily consumption of whole grains, olive oil, fruits, vegetables, legumes, nuts, and herbs. It encourages a limited intake of animal proteins, with a focus on fish and seafood. The diet’s unique features include:

• Healthy Fat Emphasis: Olive oil, avocados, nuts, and oily fish are recommended, primarily due to their beneficial omega-3 fatty acids 🌰🥜

• Fish as Preferred Protein: Fish is chosen as the primary animal protein, with limited poultry, eggs, and dairy consumption. Red meat is enjoyed occasionally🐔🎣

• Moderate Wine Intake: While water remains the main beverage, moderate wine consumption is allowed, known to complement meals. Red wine tends to be included more often than white wine (up to two small glasses 125 ml a day for men and one glass for women) 🍷

• Active Lifestyle: Daily physical activity is highlighted, encouraging enjoyable exercises. 🏃🏻‍♂️

Research Backing the Mediterranean Diet

The seminal Seven Countries Study conducted by Ancel Keys and colleagues played a pivotal role in recognizing, defining, and popularizing the Mediterranean diet as we know it today. This study carried out in the 1950s and '60s, was instrumental in highlighting the cardiovascular health benefits of the dietary pattern observed in Italy and Greece during that time. However, it's important to acknowledge that the Mediterranean diet is not uniform across the Mediterranean region due to variations in geography, economic status, health, lifestyle, and diet among the 18 countries bordering the Mediterranean Sea (Keys et al., 1986).

The traditional Mediterranean diets, as illuminated by the Seven Countries Study, featured olive oil as the principal fat source. These diets were rich in cereal products, legumes, fruits, and vegetables, moderate in fish, and low in dairy and meat products. Moderate wine consumption was also a notable aspect, particularly when enjoyed alongside meals. Nutritional analysis revealed that these diets were well-balanced, with varying total fat content, low saturated fat, very little trans fat, and abundant fibre and antioxidant vitamins (Keys et al., 1986).

The Seven Countries Study specifically focused on several Mediterranean cohorts, including Crete and Corfu in Greece, Dalmatia in Croatia, and Montegiorgio in Italy. The dietary habits in these regions were diverse but shared key elements. For instance, the Greek diet had the highest olive oil content and was characterized by elevated fruit consumption. Dalmatia, on the other hand, had a diet rich in fish, and the Italian cohort emphasized vegetable consumption. Importantly, these dietary patterns were associated with remarkably low rates of mortality from coronary heart disease, underscoring the protective effects of Mediterranean diets on heart health (Keys et al., 1986).

Incorporating the findings of the Seven Countries Study, along with subsequent research, has led to the recognition and endorsement of the Mediterranean diet as a cornerstone of healthy eating. While regional variations exist, the overarching theme of emphasizing whole, minimally processed foods, plant-based ingredients, and healthy fats remains consistent in promoting cardiovascular health and overall well-being.

Research consistently underscores the effectiveness of the Mediterranean diet in mitigating the risk of cardiovascular diseases and overall mortality (Willett et al., 1995; Fung et al., 2009; Lopez-Garcia et al., 2013). A comprehensive study involving nearly 26,000 women discovered that those who adhered to this dietary pattern exhibited a 25% lower likelihood of developing cardiovascular disease over a 12-year period (Ahmad et al., 2018). A closer examination of underlying mechanisms revealed that reductions in inflammation, blood sugar levels, and body mass index were the primary contributors to this risk reduction (Ahmad et al., 2018). Similar benefits emerged from a meta-analysis encompassing 16 prospective cohort studies that monitored over 22,000 women for an average of 12.5 years. The analysis disclosed a 24% decrease in cardiovascular disease risk and a 23% reduction in premature death risk among those with the highest adherence to the Mediterranean diet, compared to those with the lowest adherence (Pant et al., 2023).

An intriguing aspect of this dietary regimen dispels the misconception that individuals with or prone to heart disease must adhere to low-fat diets. While the quality of fats matters, the percentage of calories derived from fat carries less significance. The PREDIMED study, a primary prevention trial involving individuals with diabetes or heart disease risk factors, highlighted that a Mediterranean diet supplemented with extra virgin olive oil or nuts, without any fat or calorie constraints, lowered stroke-related mortality rates by approximately 30% (Estruch et al., 2018). The dietary fats primarily comprised healthful sources, including fatty fish, olive oil, and nuts. Remarkably, total fat intake ranged from 39% to 42% of daily calories, significantly exceeding the Institute of Medicine's recommended 20-35% fat guideline (Food and Nutrition Board, 2005). The PREDIMED trial also revealed a diminished risk of type 2 diabetes among participants (Salas-Salvadó et al., 2011).

Furthermore, interest in the Mediterranean diet's impact on ageing and cognitive function has surged (Loughrey et al., 2017; Aridi et al., 2017; Bhushan et al., 2017). Cell damage caused by stress and inflammation, contributing to age-related diseases, has been linked to telomeres specific DNA segments (telomeres are repetitive sequences of DNA found at the ends of chromosomes). Longer telomeres, associated with a lower risk of chronic diseases and longer lifespan, can be preserved by antioxidants found in foods such as fruits, vegetables, nuts, and whole grains prevalent in the Mediterranean diet (Crous-Bou et al., 2014). In a study involving 4,676 healthy middle-aged women from the Nurses' Health Study, those closely adhering to the Mediterranean diet exhibited longer telomere lengths (Crous-Bou et al., 2014).

In another Nurses' Health Study involving 10,670 women aged 57-61, dietary patterns' influence on aging was examined (Samieri et al., 2013). Healthy aging, defined as living beyond 70 years without chronic diseases or major cognitive, mental health, or physical function declines, was notably more likely among women adopting a Mediterranean-type eating regimen (Samieri et al., 2013). The increased consumption of plant foods, whole grains, and fish, moderate alcohol intake, and minimal red and processed meat intake were deemed contributing factors (Samieri et al., 2013).

Nevertheless, certain pitfalls warrant consideration. Without specific food amounts and portion sizes emphasized, there's a risk of excessive calorie intake and potential weight gain. Utilizing resources like the Mediterranean Diet Pyramid can offer guidance on food choices and proportions (Gifford, 2002). Notably, the Mediterranean diet's rich olive oil content and minimally processed foods foster satiety and long-term adherence, as demonstrated in a successful six-year weight loss trial (Shai et al., 2008).

Importantly, the research underscores the Mediterranean diet's health benefits when it involves a diverse array of foods. Its protective effects appear to stem from the combined impact of these foods, as the benefits are less pronounced when examining individual items or nutrients (Crous-Bou et al., 2014). Therefore, embracing the Mediterranean diet comprehensively is key, rather than merely incorporating olive oil or nuts into an existing diet (Crous-Bou et al., 2014).

In conclusion, research substantiates the Mediterranean diet as a prudent dietary pattern for preventing cardiovascular diseases, promoting longevity, and fostering healthy ageing. When complemented by caloric moderation, this diet can also support healthy weight loss (Gifford, 2002).

As a nutritionist on the path to becoming a registered dietitian, I'm beyond thrilled to spill the beans (and olives! 🫒) on 15 actionable tips.

1. Start with Small Changes:

Begin by making gradual adjustments to your eating habits. Swap one or two meals per week to reflect Mediterranean-style choices. (Remember the pyramid)

2. Embrace Whole Foods:

Base your meals on whole foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds. These provide a variety of nutrients and fibre.

3. Choose Healthy Fats:

Opt for heart-healthy fats like extra virgin olive oil, avocados, and nuts, which are central to the Mediterranean diet, Limit saturated fats such as those found in fatty cuts of meat, butter, lard and full-fat dairy products.

4. Include Fatty Fish:

Aim to eat fatty fish like salmon, mackerel, and sardines at least twice a week for their omega-3 fatty acids.

5. Add More Plant Protein:

Substitute some of your meat-based meals with plant protein sources like beans, lentils, and tofu.

6. Use Herbs and Spices:

Flavour your dishes with herbs and spices like oregano, basil, garlic, and turmeric instead of relying heavily on salt.

7. Snack on Nuts:

Keep a variety of nuts like almonds, walnuts, and pistachios on hand for a nutritious and satisfying snack.

8. Go for Whole Grains:

Choose whole grains like quinoa, whole wheat, and brown rice over refined grains for added fibre and nutrients.

9. Enjoy Fresh Fruits:

Incorporate a variety of fruits into your meals and snacks, not only for their natural sweetness but also for their abundance of antioxidants. Transform fruits into your new favourite dessert. Enjoy them raw or stewed. For an extra treat, pair them with low-fat yoghurt and a sprinkle of cinnamon, creating a taste sensation that's sure to be the best you've ever experienced. (you can tell that I love fruits 😜)

10. Eat Colorful Veggies:

Fill your plate with a colourful variety of vegetables to ensure a wide range of vitamins and minerals.

11. Social Dining:

Embrace the heartwarming Mediterranean tradition of communal eating. Gather with friends and family to share meals and cultivate a strong sense of connection and joy. If you find yourself challenged by portion control or overindulging during social occasions, don't worry. I'll be sharing valuable tips on mindful eating in a separate post.

12. Stay Hydrated:

Water is the beverage of choice. You can also enjoy herbal teas and infusions for added flavour and variety.

13. Moderate Red Wine:

If you choose to include alcohol, opt for moderate consumption of red wine, aligning with the recommended intake of 1 small glass (125) for females and 2 small glasses for males. However, if you don't currently consume alcohol, there's no need to start. It's perfectly fine to maintain an alcohol-free approach to the Mediterranean diet, as abstinence can often be a healthier choice than daily consumption.

14. Stay Active:

Incorporate regular physical activity into your routine, whether it's a leisurely walk, invigorating swim, or a refreshing bike ride. A minimum of 150 minutes of moderate-intensity exercise each week is recommended. Remember, every bit adds up, so even short 10-minute bursts of activity throughout the day can contribute to your overall fitness. Challenge yourself to get your heart pumping, as this not only enhances your cardiovascular strength but also boosts your overall well-being.

15. Prioritize Enjoyment:

Always keep in mind that the Mediterranean diet goes beyond nutrients, it's an invitation to relish the joy of eating. Take the time to savour each bite and fully appreciate the cultural richness of your meals. Food is a celebration of culture and a symbol of passion, often best enjoyed when shared. Prioritize high-quality, whole foods, and steer clear of highly processed options that could compromise the essence of this eating style. Let your choices reflect the authenticity and depth of the Mediterranean culinary tradition.

Remember, adopting a new eating pattern takes time. Be patient with yourself and focus on building sustainable habits that you can enjoy for the long term. Gradually incorporating these tips into your routine can help you transition to a Mediterranean-style way of eating with confidence.
