Is drinking wine in moderation good for health or not?

[Canada's guidance on alcohol and health : A paradigm shift]

Alcohol is a socially accepted food and beverage and as a cultural asset is also part of religious rituals. It can be an intoxicant and an addictive substance. It is also a noxious substance as around 3 million people worldwide die every year as a result of alcohol consumption. With the publication by Zhao et al. 2023 the relationship between the quantity of alcohol consumption and mortality reached a new level and changed the recommendations of Canada's Guidance on Alcohol and Health. The J‑curve of the French paradox became a linear relationship between alcohol consumption and mortality because the review of several control groups in previous studies revealed a recruitment error from abstinent ex-drinkers. In their systematic analysis, taking this bias into account the assessment of small amounts of alcohol as a cardioprotective stimulant had to be revised. This is a paradigm shift.
