In the present study, in the female volunteers, the ingestion of beer produced the smallest BAL over the 6 h of the experiment.This can be explained by the presence of non-alcoholic components in the beer and by the fact that this beverage has the lowest
alcohol content of those used in the study. As has been mentioned previously, the beer used contains 3.6% total sugars and 5% alcohol.Then, in this case, the first-pass metabolism (FPM) by hepatic and gastric enzymes seems to happen with greater efficiency, because, although the amount of alcohol ingested was equal for all the
beverages used in the study, the concentration of alcohol relative to the drink volume is different. Therefore the beer, with the lowest alcohol content (% v/v), will have a greater dilution effect,
