Basic knowledge of Coffee what should the elderly pay attention to when drinking coffee

Coffee is the most consumed beverage in the world today. In recent years, there seems to be a "coffee craze" in our country. A considerable number of elderly people, especially elderly intellectuals, have also formed the habit of drinking coffee.

Coffee contains caffeine, which can exhilarate people, eliminate fatigue, improve the activity of the brain, increase appetite and promote digestion. Regular moderate consumption of coffee, but also lose weight, improve exercise ability, improve learning efficiency and other functions. However, if the elderly drink coffee improperly, it can also have an adverse impact on their health. Therefore, we should pay attention to the following points:

1. The coffee drunk by the elderly should not be too strong. Espresso can speed up the heartbeat, cause premature beats, arrhythmia and excessive excitement, insomnia, etc., thus affecting rest and recovery of physical strength. It is even more inappropriate to drink coffee in the evening.

2. Elderly people with arteriosclerosis, high blood pressure and heart disease had better not drink coffee. Research by scientists in the United States shows that patients with heart disease who drink an average of 1 to 5 cups of coffee a day are about 50% more likely to have a heart attack than those who do not drink coffee. Those who drink more than 6 cups a day on average are twice as likely to develop the disease.

Japanese scholars have also proved that coffee drinkers have an increase in blood free fatty acids and blood sugar, lactic acid and pyruvate 2 hours after meals, because caffeine can increase blood lipids.

3. The elderly who suffer from ulcers should not drink coffee. Because, coffee has the effect of stimulating gastric acid secretion, and gastric acid can cause the aggravation of ulcer disease, leading to pain, bleeding and so on.

4. Old people who often drink coffee should pay attention to calcium supplements. It has been determined that drinking 2 cups of coffee will lose 15 milligrams of calcium. Therefore, the researchers pointed out that adults who drink coffee regularly need to supplement 100 milligrams of calcium every day, or drink 1 or 2 cups of milk, and can also eat calcium-rich foods such as beans, cauliflower, sesame paste, shrimp skin and kelp to make up for the loss of calcium caused by drinking coffee.

5. Old people who have drinking habits should not drink coffee after drinking, because caffeine can increase the damage caused by alcohol. Sober up with coffee after drinking is very bad for your health.

6. For the elderly with diabetes, sugar is not suitable for coffee.
