Favorable effect of modest alcohol consumption to fatty liver disease

We previously reported that modest alcohol consumption was significantly inversely associated with fatty liver disease.Feng et al pointed out a discrepancy of statistical significance between our current larger scale cohort and a previous cohort.However,the prevalence of non-alcoholic fatty liver disease was higher in non or minimal drinkers than those in light drinkers in both cohorts.They also argue that some potential co-factors such as soft drink consumption and genetic variations should be discussed.
