Scientists may have discovered the reason why red wine appears to protect the heart.
Numerous studies have suggested that moderate alcohol drinking helps to reduce the likelihood of heart disease.
The so-called "Mediterranean diet", which includes a larger intake of wine, has been credited with lower rates of heart disease in those countries, despite a higher intake of saturated fats. However, there is no clear evidence that red wine is any better than any other alcoholic drink.
But a team of scientists from Barts and the London School of Medicine, and the Queen Mary University in London, may have found a mechanism which points to the benefits of red wine.
They say it appears to interfere with the production of a body chemical which is vital to the process which clogs up arteries and increases the risk of a heart attack.
