Beer is a relatively low alcoholic beverage: from 2.3 to 7% Vol, less than wine. This does not prevent it from having devastating effects on health when you drink a lot of it. But if you consume it in moderation, it can be beneficial.
How many alcohol and calories in beer?
The alcohol content of a drink is always expressed in % Volume: it indicates the number of milliliters of alcohol per liter of drink. In everyday language, we speak of an alcoholic degree.
In terms of nutrition, we use grams of alcohol to calculate the calories of an alcoholic beverage: 1 g of alcohol = 7 calories.
But what complicates the calculation is that alcohol is lighter than water: 1 ml of alcohol does not weigh 1 g. To determine the number of grams of alcohol in a beverage, multiply by 0.8, which is the density of the alcohol.
The average contents are for 1 liter:
Table beer: 2.3 to 2.6%Vol = 18.4 to 20.8 g alcohol
Bock beer: 3.7 to 5% Vol = 29.6 to 40 g
Luxury beer: above 5.5% Vol = 44 g
Non-alcoholic beer: 1.2% Vol. Approx. = 0.96 g
Thus, when you drink a 250 ml can of beer at 7% vol., you absorb 13 g of alcohol or 91 calories provided by it. There are also more or fewer carbohydrates in beer: from 1.5 to 7%, depending on the variety (there are more than 4500 varieties worldwide). The caloric intake of 250 ml can varies between 80 and 160 calories.
If a beer from time to time is without any damage to the dietary balance and health, it is not the same when you drink it several times a day.
Including so-called “light” or “light” beers: they are made of carbohydrates but not alcohol unless they are also “alcohol-free”.
Beer: good for the heart?
Various studies have shown that one beer a day can have beneficial effects on the good state of the cardiovascular system.
This effect seems to be due to alcohol, which, in small regular doses, increases the “good” cholesterol and reduces the risk of platelet aggregation. In addition, beer contains B-group vitamins that reduce the formation of amino acid, homocysteine, which is considered a risk factor.
In the meantime, this reduction in homocysteine would also have a positive effect on the risk of osteoporosis and depression.
