[Mediterranean diet and cardiovascular disease]

Area of Science:

• Nutritional Science
• Cardiovascular Epidemiology

Context:

• Cardiovascular disease (CVD) remains a leading cause of morbidity and mortality globally.
• Dietary patterns are increasingly recognized as significant modifiable risk factors for CVD.
• The Mediterranean diet is a well-established dietary pattern associated with various health benefits.

Purpose:

• To review the epidemiological and interventional evidence supporting the role of the Mediterranean diet in cardiovascular health.
• To identify the key components of the Mediterranean diet potentially responsible for its cardioprotective effects.
• To provide evidence-based recommendations regarding the Mediterranean diet for individuals at risk of CVD.

Summary:

• Epidemiological studies consistently link adherence to a Mediterranean dietary pattern with reduced CVD morbidity and mortality.
• While interventional evidence has been limited, a recent large-scale study provides strong support for the beneficial effects of this diet.
• The cardioprotective benefits are likely multifactorial, arising from the synergistic effects of various food components rather than a single nutrient.

Impact:

• Supports the recommendation of the Mediterranean diet as a primary or adjunct strategy for CVD prevention and management.
• Highlights the importance of whole dietary patterns over single nutrient approaches in public health nutrition.
• Provides a foundation for future research into the specific mechanisms underlying the Mediterranean diet's cardiovascular benefits.
