A term used to describe the phenomenon that the French suffer to a lesser extent from circulatory and cardiac diseases than other countries, which is attributed to regular consumption of red wine. It was discovered in the 1980s by the French professor Serge Renaud and then, within a very short time, became a winged word in the wine world through the media. In the USA, red wine consumption increased by 40% virtually overnight. The "Copenhagen City Heart Study" carried out in1995 produced a similarly positive result. One of the main reasons for the possible positive effect is the substance resveratrol, which is particularly present in large quantities in red wine. However, critical minds argue that although the French may not suffer from circulatory and cardiac diseases, they do suffer more from cirrhosis of the liver.
