The passage of alcohol into the blood takes place over a period ranging from 30 minutes to 2 hours. In contrast to solid or semi-liquid food, it does not produce reserves in the body but can indirectly cause them to build up, favouring the economy of sugars and fats.
Indeed, wine with its alcohol content aids digestion, accelerates respiratory movements, and has a euphoric action.
In elderly people wine stimulates organic turnover; it is called the 'milk of old men'.
The ease with which wine is metabolised in the body makes it worthwhile in the diet of the elderly because its absorption requires no digestion.
The administration of wine in both the elderly and the young causes, among other things, a decrease in calcium and cholesterol deposits in the arteries.
For the elderly who are bedridden for a long time by infirmity and constantly in danger of complications, wine can effectively prevent lung inflammation.
