Official: Drinking Improves Thinking
It is guaranteed to raise a cheer among those who enjoy a tipple: moderate drinkers are better thinkers than teetotallers or those who overindulge.
Research by the Australian National University in Canberra suggests drinking in moderation boost your brainpower. But none at all, or too much, can make you a dullard.
A study of 7,000 people in their early 20s, 40s and 60s found that those who drank within safe limits had better verbal skills, memory and speed of thinking than those at the extremes of the drinking spectrum. The safe consumption level was considered to be 14 to 28 standard drinks a week for a man and seven to 14 for a woman.

Bryan Rodgers, from ANU's Centre for Mental Health Research, said moderate drinkers not only performed the best, but also seemed to be the healthiest. "This does not necessarily show moderate alcohol use is good for our brains - there may be other reasons we haven't measured to explain the poor performance of non-drinkers," Dr Rodgers said.
The results may reflect the fact that alcohol can reduce the risk of cardiovascular disease and increase blood flow to the brain - factors linked to improved mental function. They also support research that suggests moderate alcohol intake can reduce the risk of heart attacks and strokes by improving circulation.
