We all know not only from biology class that women’s bodies are different from men’s.
First of all on average women way less than men. But that is not the only important difference.
Let’s take a closure look at the differences in metabolism of alcohol:
Females have less “alcohol dehydrogenase enzyme” in their stomachs, an enzyme your body needs to break down the alcohol you consume. Which is why women can only drink half of what a male can drink over the same amount of time. Leading to the conclusion that women face higher risks of alcohol poisoning while attempting to keep up with their male peers.
Your brain can only tolerate a certain amount of alcohol until it shuts off due to the toxic levels. Literally, your brain is poisoned by the alcohol (which is why we call it alcohol poisoning) to the point that you are killing brain cells. And it’s the ones you use that you lose.
Low-risk drinking limits defined by the NIAAA include women should have no more than 7 drinks per week and no more than 3 drinks on any single day.
Just like girls and guys are different in their metabolism of alcohol, certain ethnic groups are also different.
People with Asian ancestry often have genetic differences in one of their metabolic enzymes for alcohol – alcohol dehydrogenase therefore will become intoxicated and “poisoned” by the build-up of an intermediary bi-product [acedaldehyde – a metabolite of alcohol] faster than Caucasians. [http://www.wisegeek.org/do-people-of-asian-descent-have-difficulty-metabolizing-alcohol.htm]. This build-up of acetaldehyde leads to a “flushing” response then profuse vomiting.
