Well you'll have to explain me how you fit "greater longevity" claimed by the page you linked with the indisputable fact that alcohol consumption drives the rate of cancers, which are one of the leading causes of death in the developed world. There is clear evidence that alcohol contents cause mutations, which in turn cause cancers when out of control. A number of deadly cancers are directly correlated with alcohol intake, such as oesophagus, stomach and digestive tract cancer. Plus, all alcohol drinks contain some amounts of formaldehyde which is a powerful poison for humans (http://www.niehs.nih.gov/health/materials/formaldehyde_508.p...).
So I'm not sure how a doctor can say with a straight face that 1-2 drinks a day has no detrimental effect on your health at all.
