Drinking: Men and Women are Unequal

When it comes to alcohol, men and women are inherently unequal and no legislation can impose sexual equality on them. It's absolutely essential for the health and safety of women to understand this inequality and act accordingly.

Contrary to common myth, not even men and women of the same height and weight experience the same effects from consuming identical amounts of alcohol.

Women are affected by alcohol more rapidly because they tend to have a higher proportion of body fat than men. As fat cannot absorb alcohol, it is concentrated at higher levels in the blood. Women also have less of a gastric or stomach enzyme (dehydrogenase) that metabolizes or breaks down alcohol before it enters the bloodstream. Because of this, women absorb up to nearly 30% more alcohol into their bloodstream than men of the same height and weight who drink the same amount of alcohol. Women are also usually shorter and lighter than men, further concentrating alcohol in their blood. Therefore, when women of average size consume one drink, it will have almost the same effect as two drinks do for the average-size man. If women eat little or skip food entirely, that compounds the effects of drinking alcohol.

Hormone changes during the menstrual cycle can also affect alcohol metabolism adversely, increasing the impact of alcohol.

The bottom line is that a woman who hopes to "hold her own" in drinking against a man is putting herself at great risk.

Although men and women are unequal when it comes to the effects of alcohol, that's not true of alcohol beverages themselves. Standard drinks of beer, wine or distilled spirits all contain equivalent amounts of alcohol... they're all the same to a breathalyzer.

There are a number of things both men and women can do to avoid problems with alcohol: For example:

The good news is that, contrary to common myth, alcohol is not fattening and research has demonstrated that for many women, drinking leads to slight weight loss. [see Alcohol, Calories and Weight]

It pays to know the facts, good or bad.
