Average lifetime alcohol intake may determine risks of cancer, mortality
Light drinkers consuming an average of less than one drink per day across their lifetime has lowest risk of mortality and developing cancers.
Even light-to-moderate levels of alcohol intake have previously been linked to increased cancer risk.
At the same time, research has demonstrated a "J-shaped" risk curve relating alcohol intake to all-cause mortality, suggesting some protective effect of light-to-moderate drinking, particularly for death from cardiovascular disease.
During the study, conducted by Andrew Kunzmann of Queen's University Belfast, and colleagues 9,559 deaths and 12,763 primary cancers occurred among the participants.
The expected J-shaped relationship between overall mortality and alcohol consumption was seen: in comparison to lifetime light alcohol drinkers (1-3 drinks per week), lifetime never or infrequent drinkers (
