Choline is an essential nutrient and the liver is a central organ responsible for choline metabolism. Hepatosteatosis and liver cell death occur when humans are deprived of choline. In the last few years there have been significant advances in our understanding of the mechanisms that influence choline requirements in humans and in our understanding of choline’s effects on liver function. These advances are useful in elucidating why non-alcoholic fatty liver disease (NAFLD) occurs and progresses sometimes to hepatocarcinogenesis
