Back to the future: the Mediterranean diet paradigm

Area of Science:

• Nutritional Science
• Public Health
• Epidemiology

Background:

• The Mediterranean diet, characterized by high olive oil, plant, and fish intake, has been linked to reduced chronic disease risk.
• The Seven Countries study first introduced the Mediterranean diet to the scientific community, establishing its health associations.
• Dietary patterns are often quantified using scores like the Mediterranean Diet Score and KIDMED index.

Purpose of the Study:

• To review the evidence on the Mediterranean diet's association with cardiovascular disease, cancer, and other chronic conditions.
• To highlight the alarming trend of Mediterranean populations abandoning traditional dietary habits.
• To examine changes in dietary patterns over time, particularly among younger generations.

Main Methods:

• Review of observational studies and intervention trials on the Mediterranean diet.
• Analysis of publications tracking dietary changes in populations from the Seven Countries Study.
• Examination of studies focusing on children and adolescents in the Mediterranean region.

Main Results:

• Accumulating data supports an inverse association between the Mediterranean diet and chronic diseases, risk factors, and mortality.
• Mediterranean populations are increasingly adopting Westernized diets, characterized by higher processed food and saturated fat intake.
• Younger generations in the Mediterranean region show poor adherence to traditional dietary patterns.

Conclusions:

• The traditional Mediterranean diet's protective effects are being undermined by widespread dietary changes.
• There is an urgent need to address the declining adherence to the Mediterranean diet, especially among youth.
• Public health interventions are crucial to reverse this trend and promote the health benefits of the Mediterranean lifestyle.
