Alcohol drinks, especially wine, have been described since 6,000 B.C. For many years in modern medicine,
wine in moderation has been considered healthy for cardiovascular prevention, i.e., recommended by
nutrition committees. Some regional guidelines still recommend one to two standard drinks per day. By the
very recent (January 2023), World Health Organization and Canadian Guidance on alcohol emphasize that
any alcoholic drink is hazardous to the health and the safe amount is zero. The risk starts with every single
drop. It was also nicely summarized in the manuscript “Alcohol-dose question and the weakest link in a
chemical interplay” (Explor Cardiol. 2023;1:15–25. doi: 10.37349/ec.2023.00003) especially from the
standpoint of a researcher in the cardiovascular arena. The newest recommendations are based on
observational studies and their meta-analysis, therefore establishing associations, pointing out that alcohol
may somewhat prevent cardiovascular diseases and diabetes type 2, but with a significant increase in
non-cardiovascular morbidity and mortality, especially cancers. Previous recommendations, therefore, may
be obsolete as they were based on studies where abstainers from alcoholic beverages had inherent higher
risks. The current controversy with conflicting guidelines for alcoholic beverage consumption in the era of
precision medicine may stimulate more fundamental investigations up to genetic ones and find the
cause-effect relations. In the era of precision medicine, it may come closer to discovering the causes of
cancers and many other diseases, enabling predictions of reactions to alcoholic beverages by each person,
not just in the population.
