Implementing a Mediterranean-Style Diet Outside the Mediterranean Region.

PURPOSE OF REVIEW: Populations surrounding the Mediterranean basin have traditionally reaped health benefits from a Mediterranean diet (MedDiet), which may benefit Westernized countries plagued by chronic disease. But is it feasible to implement beyond the Mediterranean? To answer this question, we present evidence from randomized controlled trials that achieved high dietary compliance rates with subsequent physical and mental health benefits. RECENT
FINDINGS: In the 1960s, the Seven Countries Study identified dietary qualities of Mediterranean populations associated with healthy aging and longevity. The PREDIMED study confirmed reductions in CVD-related mortality with a MedDiet; a meta-analysis in over 4.7 million people showed reduced mortality, CVD-related mortality, and reduced risk of Parkinson's and Alzheimer's disease. Continually emerging research supports the MedDiet's benefits for chronic diseases including metabolic syndrome, cancers, liver disease, type 2 diabetes, depression, and anxiety. We summarize components of studies outside the Mediterranean that achieved high compliance to a Med-style diet: dietitian led, dietary education, goal setting, mindfulness; recipe books, meal plans, and food checklists; food hampers; regular contact between volunteers and staff through regular cooking classes; clinic visits; and recipes that are simple, palatable, and affordable. The next step is testing the MedDiet's feasibility in the community. Potential obstacles include access to dietetic/health care professionals, high meat intake, pervasive processed foods, and fast food outlets. For Western countries to promote a Med-style diet, collective support from government, key stakeholders and policy makers, food industry, retailers, and health professionals is needed to ensure the healthiest choice is the easiest choice.
