In their systematic review and meta-analysis, V. Houttu et al. (Amsterdam University Medical Center, The Netherlands) summarise and assess the evidence for dietary interventions NAFLD patients.
In these patients, Mediterranean and hypocaloric dietary interventions favouring unsaturated fatty acids result in improvements in intrahepatic lipid content and transaminases. Nevertheless, many dietary intervention studies are combined with exercise interventions. There is a paucity of ample-sized studies on the clinically relevant stages of NAFLD, with multiparametric imaging and liver histology as outcome measures. Hence, the optimal dietary invention in NAFLD remains to be defined.
