A study has suggested that drinking alcohol every day may cut the risk of heart disease in men by more than a third. But the research has come under fire from scientists who say the study is flawed and should not encourage anyone to drink more.

The controversial study found that men who drank moderate, high and very high levels of alcohol had a lower risk of coronary heart disease.

Heavy drinking can damage organs and lead to early death. According to the World Health Organization, 76 million of the estimated 2 billion people in the world who drink alcohol suffer ill health as a result, and alcohol causes around 1.8 million deaths every year.
