(Dailymail) - Alcohol guidelines should be updated to include a ‘binge drinking limit’ – the maximum amount that should be consumed in one day, an expert has told MPs. Nick Heather, a professor of alcohol and drug studies at Northumbria University, said that on no account should overall recommended drinking levels be raised. Instead, the Government should issue advice on safe drinking limits for a week – and give an upper limit for any one day. Professor Heather said the ‘binge drinking limit’ could be set to eight units a day, ‘or maybe a bit lower’. He suggested it could be six units for women.
