“Men and women are obviously different, but did you know that this is true even when it comes to how alcohol affects them? There’s a reason why the U.S.D.A. Dietary Guidelines recommend up to two drinks a day for men and up to only one for women: Women have less body water than men, and therefore are more likely to have a higher blood-alcohol content (BAC) than men after drinking the same amounts. Further, estrogen, the primary female sex hormone, suppresses the process that leads to the breakdown of alcohol, another contributor to a higher BAC in women.”
