occasional drinkers or ex-drinkers were included as abstainers, resulting in the increased mortality in that group. However, the J-curve for total and CHD mortality was reconfirmed by studies that took the mentioned confounders into account. There seems to be little discussion of what proportion of individuals classified as abstainers are those already at greater risk of mortality due to chronic conditions and do not or cannot consume alcohol for reasons of health or harmful interactions with medication. The observed decrease in mortality of light-to-moderate drinkers compared to never drinkers might be partially explained by superior health and social status of the drinking group; however, the protective effect of alcohol in light to moderate drinkers remains significant even after adjusting for these confounders. Additionally, confounders such as underreporting of alcohol intake might lead to the underestimation of how much mortality is reduced in light-to-moderate drinkers. A 2010 study confirmed the beneficial effect of moderate alcohol consumption on mortality. Subjects were grouped into abstainers, light, moderate, and heavy drinkers. The order of mortality rates from lowest to highest were moderate, light, heavy, and abstainers. The increased risk for abstainers was twice the mortality rate as for moderate drinkers. This study specifically sought to control for confounding factors including the problem of ex-drinkers considered as non-drinkers. According to another study, drinkers with heavy drinking occasions (six or more drinks at a time) have a 57% higher all-cause mortality than drinkers without heavy drinking occasions. Mortality is lowest among young abstainers and highest among young heavy drinkers. According to a 2018 study people who had more than seven and up to 14 standard drinks per week, were likely to have their life expectancy shortened by around 6 months. Those who consumed over 14 drinks and up to 25 per week were likely to have 1–2 years taken off their lifespan, and a consumption of over 25 standard drinks per week correlated with 4–5 fewer years. In contrast to studies of Western cultures, research in other cultures has yielded some opposite findings. The landmark INTERHEART Study has revealed that alcohol consumption in South Asians was not protective against CAD in sharp contrast to other populations who benefit from it. In fact Asian Indians who consume alcohol had a 60% higher risk of heart attack which was greater with local spirits (80%) than branded spirits (50%). The harm was observed in alcohol users classified as occasional
