It has been suggested that France's high red wine consumption is a primary factor in the trend. This hypothesis was expounded in a "60 Minutes" broadcast in 1991. The program catalysed a large increase in North American demand for red wines from around the world. It is believed that one of the components of red wine potentially related to this effect is resveratrol; however, the authors of a 2003 study concluded that the amount of resveratrol absorbed by drinkers of red wine is small enough that it is unlikely to explain the paradox.
