Mediterranean diet as the ideal model for preventing non-alcoholic fatty liver disease (NAFLD)

Abstract

The prevalence of nonalcoholic fatty liver disease (NAFLD) has dramatically increased in the 2–3 last decades and it represents the most frequent global cause of liver disease, affecting 25% to 45% of adults in most studies (1). The worldwide elevation in the population rates of NAFLD has come in parallel with rising unprecedented pandemics of obesity and diabetes. There is no specific medication for NAFLD and dietary/lifestyle modifications are the main foundations for the treatment of NAFLD. They are also very likely to be effective for its primary prevention. In this context, a dietary pattern that meets most requirements to become the ideal model for the prevention of NAFLD is the traditional Mediterranean diet (2). In addition to the potential for preventing NAFLD, the Mediterranean diet has sufficiently demonstrated its great ability to improve cardiovascular health. The accrual of prospective and well conducted studies showing cardiovascular benefits associated with better adherence to a high-quality food pattern is superior for the traditional Mediterranean food pattern than for any other dietary pattern (3).
