Beer is natural alchogolic drink which contains many connections established in the process of fermention and coming into it from plant material. The main components of beer are water (91-93%), carbohydrates (1,5-4,5%), ethanol (3-7%) and nitrogen-containing substances (0,2-0,65%). Other components are denoted as minor.
Ethanol which is coming to an organism with a beer does not have a dehydrating effect, due to the high content of water in this drink, in other words, the use of beer, unlike vodka, you can not inject a lethal dose of alcohol.
However, it should be noted that in recent years on the market of alcoholic beverages is a new kind of beer with high alcohol content - up to 12% (strong beer). Use of this beer in the same amount as usual, of course, entails a chain of negative effects resulting from concurrent toxic effects of alcohol and other biologically active compounds.
