Consumption and responsible service of alcohol. It can be our best ally or our worst enemy.
Although the majority of people use alcohol very responsibly, the abuse of this interesting product, for a small minority of individuals, can cause physical harm with health risks, lead to illegality and lead to antisocial conduct. The professional bartender, in his work, can play a very important role - and must do - in the intelligent service and promotion of alcohol. He will also have to know well the laws that regulate consumption to apply them in the workplace.
Alcohol or ethanol is one of the main constituents of alcoholic beverages and characterizes their type. Consumption concerns the private behavior of people but bartenders and waiters play an important role since with their behavior they can influence their consumption.
It is not essential for humans, it provides about 7 calories per gram, a little less than fat and almost double the sugar. It is important to know how much alcohol there is in a dose of drink served to the customer, how much is the acceptable dose of daily consumption and other notions.
Alcohol is metabolized almost entirely by the liver and our body can assimilate it without consequences only if certain quantities are not exceeded. The acceptable daily consumption dose is 0.6 grams per kg of body weight while the limit not to be exceeded is approximately 1 gram per kg of body weight.
Normally a 70 kg person can metabolize about 6 grams of alcohol every hour, it is therefore preferable to distribute the alcohol intake as much time as possible.
The abuse of alcohol is dangerous, the ingestion of considerable and continuous quantities, especially on an empty stomach and perhaps high-alcohol drinks can cause: injuries to the digestive system, alterations to the central nervous system (coordination of movements, slowed reflexes, visual disturbances, etc. .), disorders of sexuality, create addiction phenomena, increase the risk of serious diseases.
