J Curve Relationship

A relationship between the risk of death from a particular process or activity, in which the mortality initially falls to a nadir, after which it rises. The classic J curve relationship occurs with alcohol—especially wine—consumption, in which cardiovascular mortality is higher in non-drinkers than in those who consume one or two glasses of wine per day. When alcohol consumption exceeds 50 g/day, the health benefit of alcohol consumption disappears and the mortality related to increased alcohol consumption rises
