The advantages and disadvantages of drinking coffee in a healthy life

According to relevant data, healthy people drinking a cup of instant coffee (about 2-3 teaspoons) can lead to tachycardia. If you drink at night, it will cause insomnia. For people suffering from some kind of cardiovascular disease, there will also be a high blood pressure phenomenon. Drinking coffee for people with gastric and duodenal ulcers will increase gastric acid and stimulate gastric mucosa and ulcer surface, which is disadvantageous to wound healing. So, when is the best time to drink coffee? According to foreign materials, the best time to drink coffee is: summer and autumn festival at 4: 00 p.m. and winter and spring festival at 3: 00 p.m. to 5 p.m. As this is the time when the human body feels the most tired, drinking a cup of coffee at this time can not only increase nutrition, but also lift spirits and benefit work.

Coffee and Cancer French researchers have found that coffee drinkers will greatly increase the incidence of pancreatic cancer. According to their survey, people who drank up to 60,000 cups of coffee were twice as dangerous as those who did not drink coffee. Greek cancer researchers found in 1981 that women who drank coffee were twice as likely to have ovarian cancer as women who did not drink coffee. Drinking coffee can also lead to breast cysts in women. Although breast cysts are different from cancer, they can also turn into cancer. It is reported that women with cysts are four times more likely to develop breast cancer than normal women. Coffee and premenstrual syndrome refers to a series of abnormal symptoms of women before menstruation, such as emotional instability, mental tension, irritability, anxiety, lack of concentration, insomnia, headache, breast pain and so on.

According to a recent report in the American Journal of Public Health, women who drink caffeinated drinks are prone to premenstrual syndrome. Therefore, for women with PMS or women who are in the habit of drinking caffeine, it is best not to drink caffeinated drinks such as coffee and tea before menstruation, let alone strong coffee and strong tea. Coffee and coronary heart disease, doctors from the Johns Hopkins Institute of Medicine and other units conducted a study on 1130 male medical students to see if coffee consumption is related to the occurrence of coronary heart disease.

After 19 to 35 years of follow-up, it was found that people who drank five or more cups of coffee a day were 2.8 times more likely to suffer from coronary heart disease than those who did not drink coffee. if other possible causes of coronary heart disease (such as age, smoking, high blood pressure, serum cholesterol concentration, etc.) are excluded, the relative risk is as high as 2.49 times. According to this, experts believe that there is a certain relationship between coffee consumption and the occurrence of coronary heart disease, and people who drink more coffee (5 or more cups a day) have an increased risk of coronary heart disease, which is 2 to 3 times higher than those who do not drink coffee.
