Abstract

The Mediterranean diet is characterized by a high intake of fruits and vegetables, whole grains, legumes, nuts, fish, and olive oil.

This dietary pattern promotes a low intake of saturated fats and animal protein.
Moderate consumption of fermented dairy products and red meat is recommended.
The diet is rich in antioxidants, fiber, and monounsaturated fats.
It may support an adequate balance of omega-6 and omega-3 fatty acids.
Key bioactive compounds associated with health benefits include phytosterols and probiotics.
Awareness of local agricultural and culinary traditions may enhance health outcomes in regions with Mediterranean-like climates.

Simplified

The Mediterranean diet is currently considered a healthy dietary pattern. It includes a great variety of foods, which are eaten in moderation and within a positive social environment. The generic term "Mediterranean diet" was born after the "Seven Countries Study" led by Ancel Keys around 1960. This dietary pattern is characterized by a high intake of fruits and vegetables, whole grains, legumes, nuts, fish, white meats and olive oil. It also includes moderate consumption of fermented dairy products, low intake of red meat and drinking wine with moderation during meals. Nutritionally, this diet is low in saturated fats and animal protein, high in antioxidants, fiber and monounsaturated fats, and exhibits an adequate omega-6/omega-3 fatty acid balance. The main bioactive compounds, which explain the health benefits of this dietary pattern, are antioxidants, fiber, monounsaturated and omega-3 fatty acids, phytosterols and probiotics. This diet is not exclusively confined to the Mediterranean Basin. Central Chile has a Mediterranean climate and our agriculture and culinary traditions are similar to those found in Mediterranean countries. Therefore, it is fundamental to increase awareness about the richness of our natural produce as well as our culinary culture, which may bring many health benefits and improve the quality of life in our population.
