Just in time for the season of excess, new draft alcohol guidelines have cut the recommended weekly limit by four standard drinks.

In the first update in a decade, draft NHMRC guidelines released on Monday advise sticking to a maximum of 10 standard drinks (10g alcohol per drink, equivalent to 100ml wine) in total a week.

This is a departure from the previous guidelines, set in 2009, which advised “no more than two standard drinks” on any day — or 14 per week.

Australia’s Chief Medical Officer, Professor Brendan Murphy, said the proposed guidelines were the result of a robust and comprehensive review process over the past three years.
