Mediterranean diet and metabolic diseases

PURPOSE OF REVIEW: The objective of this article is to present evidence illustrating the relationship between Mediterranean diets and metabolic diseases, including obesity, type 2 diabetes, and the metabolic syndrome, and to briefly discuss potential mechanisms by which these diets can help in disease prevention and treatment. RECENT FINDINGS: Although the Mediterranean diet has long been celebrated for its impact on cardiovascular health, mounting evidence indicates a favorable effect on obesity and type 2 diabetes, as well. While health promotion strategies aimed at preventing adult obesity are emphasizing components of Mediterranean dietary patterns, a role for Mediterranean diets in attenuating the inflammatory burden associated with type 2 diabetes is also emerging. Moreover, a lower prevalence of the metabolic syndrome is associated with dietary patterns rich in fruits, vegetables, whole grains, dairy products, and unsaturated fats. Both epidemiological and interventional studies have revealed a protective effect of the Mediterranean diet against mild chronic inflammation and its metabolic complications. SUMMARY: Mounting evidence suggests that Mediterranean diets could serve as an anti-inflammatory dietary pattern, which could help fighting diseases that are related to chronic inflammation, including visceral obesity, type 2 diabetes and the metabolic syndrome.
