Key Components of the Mediterranean Diet
The Mediterranean diet is characterized by high consumption of olive oil, vegetables, fruits, whole grains, legumes, nuts, fish, and moderate wine consumption, while limiting red meat, processed foods, and sweets. 1
Core Food Components
- High intake of olive oil: Extra virgin olive oil serves as the primary source of fat in the Mediterranean diet 1
- Abundant consumption of plant foods:
- Regular consumption of nuts and seeds 1
- Moderate to high consumption of fish and seafood 1
- Low to moderate consumption of dairy products, primarily in the form of cheese and yogurt 1, 2
- Limited consumption of red meat 1, 3, 2
- Moderate consumption of wine, typically with meals 1, 3, 2
Nutritional Characteristics
- High in monounsaturated fats primarily from olive oil 3, 2
- Low in saturated fats from animal sources 3, 2
- Rich in dietary fiber from plant foods 1
- High in antioxidants from fruits, vegetables, olive oil, and wine 3, 4
- Balanced omega-6/omega-3 fatty acid ratio 3
- Rich in polyphenols from olive oil, fruits, vegetables, and wine 1, 4
Eating Patterns and Culinary Practices
- Home-cooked meals prepared using traditional methods 5
- Moist, lower-temperature cooking methods rather than high-heat methods 5
- Eating meals in company as a social activity 5
- Limited snacking between meals 5
- Seasonal and local food consumption 4, 5

Health Benefits
- Cardiovascular protection: The Mediterranean diet has been shown to reduce the risk of myocardial infarction, stroke, and cardiovascular mortality 1
- Reduced mortality: Studies have demonstrated lower all-cause mortality rates among those adhering to the Mediterranean diet 1, 4
- Prevention of heart failure: The Mediterranean diet has been associated with lower rates of heart failure development 1
- Anti-inflammatory effects: Components of the diet have been shown to reduce inflammation 1, 4
- Improved gut health: The diet promotes beneficial gut microbiota through its high fiber content and polyphenols 1
Implementation Considerations
- Mediterranean diet score: Adherence can be measured using scoring systems that assess intake of key components 1
- Adaptability: The diet can be adapted to different cultural contexts while maintaining core principles 3, 5
- Sustainability: The Mediterranean diet is considered environmentally sustainable 4
Comparison with Other Healthy Dietary Patterns
- Similarities with DASH diet: Both emphasize fruits, vegetables, whole grains, and limited red meat 1
- Differences from DASH diet: The Mediterranean diet places more emphasis on olive oil and moderate wine consumption, while DASH focuses more on low-fat dairy and sodium restriction 1
The Mediterranean diet represents not just a set of food recommendations but a cultural approach to eating that emphasizes whole, minimally processed foods and traditional preparation methods. Its health benefits are attributed to the synergistic effects of its components rather than any single food or nutrient 4, 5.
