(ThaAge) - SERGE Renaud, who has died aged 84, was a research scientist who became a hero of the French wine industry when he announced on American television that drinking red wine is good for the heart. Renaud's name was closely associated with the "French Paradox" - the observation that French people live longer than Americans and have fewer heart attacks despite the fact that they smoke more, take less exercise and enjoy delights such as foie gras, confit de canard and Brillat-Savarin - so fatty that it is known as "triple-cream" cheese.
