Does more alcohol remain in the blood of men or women?

The correct answer is that women retain more alcohol in their blood compared to men. This difference is primarily due to physiological and biological factors. Women generally have a higher percentage of body fat and a lower percentage of water than men. Since alcohol is water-soluble and not fat-soluble, this means that when women consume the same amount of alcohol as men, it tends to be more concentrated in their system.

Additionally, women often produce lower levels of the enzyme alcohol dehydrogenase, which breaks down alcohol in the stomach. As a result, a greater proportion of the alcohol consumed by women enters the bloodstream rather than being metabolized before absorption.

While age and other factors can influence alcohol metabolism, the fundamental biological differences between men and women are the primary reasons for the variation in blood alcohol concentration.
