The study reveals an inverse association between Mediterranean diet and NAFLD. Mediterranean diet offers protection against diabetes and CVD among subjects with NAFLD.
Background and aims: We assessed the association of Mediterranean diet with NAFLD and their interaction in predicting ten-year diabetes onset and first fatal/non-fatal cardiovascular disease (CVD) incidence. Methods: The ATTICA prospective observational study in Athens, Greece included 1,514 men and 1,528 women (> 18 years old) free-of-CVD at baseline. Liver steatosis and fibrosis indices were calculated. Mediterranean diet adherence was assessed through MedDietScore. At the ten-year follow-up visit, CVD evaluation was performed in an a priori specified subgroup of n = 2,020 participants and diabetes onset in n = 1,485 free-of-diabetes participants. Results: MedDietScore was inversely associated with steatosis and fibrosis; e.g. in the case of the TyG index the Odds Ratio (OR) of the 3rd vs. 1st MedDietScore tertile was = 0.53, [95% Confidence Interval (95% CI) (0.29, 0.95)] and the associations persisted in multi-adjusted models. NAFLD predicted incident diabetes prospectively over a ten year period [HR = 1.87, 95% CI (0.75, 4.61)] and the association remained significant only in subjects with low MedDietScore (below median) whereas diabetes onset among subjects with higher MedDietScore was not influenced by NAFLD. Similarly, NAFLD predicted CVD [Hazard Ratio (HR) = 3.01, 95%CI(2.28, 3.95)]; the effect remained significant only in subjects with MedDietScore below median [HR = 1.38, 95% CI (1.00, 1.93)] whereas it was essentially null [HR = 1.00,95% CI (0.38, 2.63)] among subjects with higher score. Mediation analysis revealed that adiponectin and adiponectin-to-leptin ratio were the strongest mediators. Conclusions: We report an inverse association between Mediterranean diet and NAFLD. Mediterranean diet protected against diabetes and CVD prospectively among subjects with NAFLD. (c) 2020 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.
