Briefly noted: V Ajmera et al. Clin Gastroenterol Hepatol 2018; 16: 1511-20. This study with 285 participants showed that modest alcohol consumption was associated with a lower odds of NASH resolution on biopsy over 4 years compared with no alcohol consumption (OR 0.32). The associated editorial (pg 1404-6) provides a table with 8 studies that reveal conflicting results on this issue.
My take (borrowed from editorial): “Clinicians should not recommend modest drinking” as a way of improving liver health.
