It showed that when you simply compare alcohol consumption and health outcomes, you find a clear beneficial effect of moderate alcohol consumption. But if you take former drinkers out of the abstainers group, then the benefits don’t look so rosy – in fact, they all but disappear.
Meanwhile, another team of researchers studied people whose bodies cannot process alcohol properly – and therefore who generally don’t drink alcohol at all – and found those with this genetic marker had better cardiovascular health and a lower risk of coronary heart disease than those without it.
Hah! Causation and correlation, suckers.
