Diet quality and its association with nonalcoholic fatty liver disease and all-cause and cause-specific mortality.

Commentary

Healthy diet has been recommended for NAFLD, although it is not clear whether improving diet quality can prevent mortality. ER Yoo et al. aim to assess the impact of quality of diet on NAFLD and mortality in subjects with and without NAFLD.

High diet quality was inversely associated with NAFLD and was positively associated with a lower risk for cancer-related and all-cause mortality in subjects without NAFLD. Primary prevention against NAFLD with high diet quality in those without the condition may be the ideal way to reduce all-cause mortality in subjects without NAFLD and curb the rising incidence of NAFLD.
