Our body treats alcohol as a poison, and like any organism begins to deal with it, producing the enzyme alcohol dehydrogenase (the main provider of it is the liver). The enzyme becomes active when the alcohol comes to your stomach.Development of this enzyme depends on the sex, age and genetic predisposition. That is why men get drunk more slowly than women. However, with age, this ability is reduced.
When you eat, the valve between the stomach and the small intestine closed - the body knows that the food should be well digested, so the enzyme has a lot of time left to work on alcohol.
If you decide to drink a glass on empty stomach, alcohol is almost non-stop passes the stomach and enters the small intestine, where the surface area of over 200 m2.
Do not combine alcohol and aspirin, if you do not like a hangover. Aspirin reduces the production of the enzyme. Studies in the 90s of the 20th century showed that the level of alcohol in the blood of those who took a couple of aspirin before drinking, 26% higher than those who did not take the drug.
In some measure alcohol prolongs life. Of course, this does not apply to chronic alcoholics. Almost every month there are new studies that show that moderate alcohol consumption prolongs life. I think that all at least once stumbled in magazines on the advice to drink a glass of dry red wine a day or even a couple of times a week (unless contraindicated).
Alcohol does not kill brain cells, but suppresses them. If you drink a standard dose, only 0.08% of alcohol reaches to your brain with blood, and if you visit a major party - get as much as 0.25%. But these percentages do not affect the cells of the brain (chronic alcoholism and its effects on the cells of the liver and other organs is another story altogether).
