Dietary Patterns Are Associated with Likelihood of Hepatic #Steatosis among US Adults

Non‐alcoholic fatty liver disease (NAFLD) is a rapidly growing public health problem. In this study, we explored the association between dietary patterns (DPs) and fatty liver and liver function tests..

..Of the 20643 eligible participants, 45.7% had prevalent fatty liver. Three DPs collectively explained 50.8% of variance in dietary nutrients consumption. The first DP was representative of a diet containing high levels of saturated and mono‐unsaturated fatty acids; the second DP comprised vitamins and trace elements; and the third DP was mainly representative of polyunsaturated fatty acids.

In adjusted multivariable regression models, participants in the top quarter of the second DP had 34% lower odds of prevalent fatty liver [odds ratio 0.66 (95% confidence interval [CI] 0.43‐0.71)], while those in the quarter of the first DP subject had 86% higher odds [1.86 (95% CI: 1.42‐2.95)] of prevalent fatty liver, relative to participants in the bottom quarter of each of the DPs.

Our findings suggest that a diet with high load of vitamins, minerals and fiber content is associated with lower NAFLD prevalence.
