A percepção dos efeitos do álcool mudou muito em 20 anos e o RU alterou radicalmente as suas linha orientadoras de consumo (em Janeiro de 2016) para 14 volumes de álcool por semana, uma das mais restritivas na Europa. Detalhes da decisão e das quantidades recomendadas:

Citando:
"The review found that the benefits of alcohol for heart health only apply for women aged 55 and over - and even then it's in very small amounts, around five units a week.
The guidelines say: "There is no justification for recommending drinking on health grounds - nor for starting drinking for health reasons."
It also says that evidence in support for drinking alcohol in small amounts to maintain good health was "weaker than it was at the time of 1995"."
(...)
Is there a safe drinking level?
No. The new recommendations are at pains to point out that these guidelines are not for "safe" drinking, but rather just at minimising risk of illness.
All alcohol consumption carries some risk, the guidance says.
"The vast majority of the population can reduce health risks further if they reduce drinking below the guideline levels, or do not drink at all," the guidance says.
Drinking above the new recommended 14 units a week is the point at which a person's risk of an early death increases by 1% - the equivalent amount of risk as driving a car."
PS. Muito interessante a tabela com os limites de diversos países (Espanha, 38; RU, 14). Se a ciência e investigação é a mesma, porque é que não há consenso nos limites, nem sequer na Europa?
