(Independent) - A new government campaign is to warn drinkers that consuming two large glasses of wine or two strong pints of beer a day triples their risk of developing mouth cancer. New adverts aim to show that even drinking just over the recommended daily limit for alcohol increases the risk of serious health problems. NHS recommendations are that men should not regularly drink more than three to four units a day, and women not more than two to three. Adverts will run under the Change4Life banner and people will be able to access a new online calculator to work out how much they are drinking. Two million leaflets will also be made available to Change4Life supporters and health professionals across England.
