"Ever hear the saying that drinking beer before wine can reduce hangover symptoms? It's just a myth, according to a small randomized study published Feb. 1, 2019, in The American Journal of Clinical Nutrition. Researchers found out by dividing 90 men and women (ages 19 to 40) into four groups. One group drank beer first, and then wine; another group drank wine first, and then beer; and the last two groups drank only beer or only wine. All of the participants drank until they were intoxicated (measured by a breath test), and then rated their hangover symptoms (like headache and nausea) on the day after drinking. The process was repeated a week later, but this time the beer-first group drank wine first; the wine-first group drank beer first; the wine-only group drank only beer; and the beer-only group drank only wine. The results: everyone experienced hangovers, no matter what they drank or the order in which they drank it. The strongest predictors for hangover intensity were perceived drunkenness and vomiting. The bottom line: Drinking too much is unhealthy for anyone. If you drink at all, drink in moderation. That means no more than one drink per day for women, no more than two drinks per day for men."
