Coffee is one of the most widely consumed beverages in the world today. In recent years, a "coffee craze" seems to have quietly emerged in our country as well. A considerable number of elderly people, especially those with certain health conditions, have also started to enjoy coffee.
Coffee contains caffeine, which can invigorate the spirit, eliminate fatigue, improve brain activity, and also stimulate appetite and promote digestion. Regular and moderate consumption of coffee can also aid in weight loss, enhance athletic performance, and improve learning efficiency. However, improper coffee consumption by the elderly can adversely affect their health. Therefore, the following points should be noted:
1. The coffee consumed by the elderly should not be too strong. Strong coffee can accelerate the heart rate, causing premature beats, arrhythmia, over-excitement, and insomnia, thereby affecting rest and physical recovery. It is particularly not advisable to drink coffee in the evening.
2. Elderly individuals with arteriosclerosis, high blood pressure, or heart disease should preferably avoid coffee. Research by American scientists has shown that heart disease patients who drink an average of 1 to 5 cups of coffee per day have about a 50% higher chance of having a myocardial infarction than non-drinkers; for those who drink an average of more than 6 cups per day, their risk of the condition doubles.
Research by Japanese scholars has also proven that for coffee drinkers, free fatty acids in the blood increase two hours after a meal, while blood sugar, lactic acid, and pyruvic acid also rise. This is because caffeine has the effect of increasing blood lipids.
3. Elderly people with ulcers should also avoid drinking coffee. This is because coffee stimulates the secretion of gastric acid, which can aggravate ulcers, leading to pain and bleeding.
4. Elderly people who regularly drink coffee should pay attention to calcium supplementation. It has been determined that drinking 2 cups of coffee results in a loss of 15 mg of calcium. Therefore, researchers point out that adults who regularly drink coffee need to supplement 100 mg of calcium daily, or drink 1 to 2 glasses of milk. They can also eat calcium-rich foods such as legumes, daylilies, sesame paste, dried small shrimps, and kelp to make up for the calcium loss caused by coffee consumption.
5. Elderly people who drink alcohol should not have coffee after drinking, as caffeine can increase the damage caused by alcohol. Using coffee to sober up after drinking is very detrimental to health.
6. Elderly individuals with diabetes should not add sugar to their coffee.
