It is ...if you recall exactly what was said on the radio ! I'm not convinced about moderate drinking increasing longevity compared to "teetotalers" - are the latter life-long, or ex-alcoholics?
I've already said it may raise "good" cholesterol and lower "bad" cholesterol.
I'm cautious about putting a figure (20%) on the benefits.
Nobody should justify taking up drinking on health grounds.
The limits thought to be safe for women are lower than for men because of how their body treats alcohol, but as 1/5 women ( and 1/3 men ) in the UK drink more than the recommended amounts, there is clearly a problem in the UK.
As for the Philippines (never forgetting this is FILIPINO UK forum), maybe it's a reflection of the conservative filipinos I know, but I don't think alcohol is such a problem, compared to UK.
Several filipina friends don't drink at all, unlike my British friends. Even at the Aegis Band concert which I was at last May, drinking was much more restrained than at similar events in UK. This has to be my opinion, because hard facts are more difficult to obtain from Philippines than UK.
