The association between non-alcoholic fatty liver disease (NAFLD) and advanced fibrosis with blood selenium level based on the NHANES 2017-2018

Abstract

This study showed that blood selenium level were positively association with NAFLD among US population. Participants with lower blood selenium level showed a higher percentage of advanced liver fibrosis. Blood selenium is more likely to cause NAFLD and liver fibrosis due to imbalances in selenium homeostasis rather than dietary selenium intake.Key messagesHigh blood selenium level was association with NAFLD diagnosed by vibration controlled transient elastography.Participants with lower blood selenium level had high percentage of advanced liver fibrosis.NAFLD and liver fibrosis are caused by an imbalance of selenium homeostasis, not by dietary selenium intake.
