So many questions...
How do rates of cancer and cardiovascular disorders compare between populations using alcohol and those who don't e.g. Muslim?
Why do the limits ignore biological differences between men and women?
How do more complete lifestyle indicators throw light on causality attributed to alcohol e,g, good diet, exercise and alcohol consumption vs poor diet, sedentary and alcohol consumption?
Was the research leading to the new limits "cooked"? El Reg passim.
Why is alcohol described as having no beneficial effects? We've been doing it for over 5000 years. Stress relief? Social cohesion? And yes, I'm aware of the negative effects from excessive consumption.
