Above all, because of the limited number of studies that examined the association between ARC and alcohol consumption, studies in different ethnicities remain warranted 4 . (nature.com)
Several studies have found a J-shaped relationship between alcohol consumption and health, meaning that risk is minimized at a certain (non-zero) consumption level, and drinking below or above this level increases risk, with the risk level of drinking a large amount of alcohol greater than the risk level of abstinence. (wikipedia.org)
Other studies have found a dose-response relationship, with lifetime abstention from alcohol being the optimal strategy and more consumption incurring more risk. (wikipedia.org)
