22 Jan 2018 --- Adolescent drinking can predict the risk of developing liver disease later in life, confirms a major new study conducted in Sweden. Alcohol is the leading cause of liver cirrhosis and liver-related deaths, and guidelines for safe alcohol intake in men might have to be revised downwards, the researchers report in the Journal of Hepatology. Current recommended cut-off levels in some countries suggest that safe alcohol consumption for men to avoid alcoholic liver disease is 30 grams per day, roughly equivalent to three drinks.
