Red wine may not be as good for you as hoped, say scientists who have studied the drink's ingredient that is purported to confer good health.
The team tracked the health of nearly 800 villagers from the Chianti region of Italy to see if their local tipple had any discernable impact.
They found no proof that the wine ingredient resveratrol stops heart disease or prolongs life.
Experts say more research is needed to get a definitive answer.
The British Heart Foundation is carrying out its own resveratrol study.
