If the elderly drink coffee in moderation, it is beneficial to the body, but if it is consumed in excess for a long period of time, it may affect sleep and so on.
Coffee is a beverage made from coffee beans, and it is beneficial to the health of the elderly to drink coffee in moderation. On average, every 100g of coffee contains nutrients such as 68.9g of carbohydrates, 17.1g of proteins, 0.132g of magnesium, 2.013g of potassium, etc., and moderate drinking of coffee by the elderly can provide the body with the above mentioned nutrients.
However, since coffee contains a large amount of caffeine, tea polyphenols, etc., if the elderly drink too much for a long period of time, it is easy to stimulate the central nervous system and vasomotor center, which may lead to emotional tension, shortness of breath, and elevated blood pressure.
If the elderly drink too much coffee at night, it is also easy to make the brain in a long-term state of excitement, affecting the quality of sleep, especially insomnia.
Elderly people who suffer from arteriosclerosis, hypertension, excessive stomach acid, and peptic ulcers are advised to drink less or try not to drink coffee.
