The following six kinds of people should not drink coffee:
Suffering from high blood pressure, coronary heart disease, atherosclerosis and other diseases - long-term or heavy drinking coffee can cause cardiovascular disease.
Older women - coffee reduces calcium and causes osteoporosis. After menopause, women need 10 times more calcium per day.
Stomach patients - drinking too much coffee can cause stomach problems to worsen.
Pregnant women - drinking too much coffee can cause fetal malformation or miscarriage.
Vitamin B1 deficiency - Vitamin B1 can maintain the balance and stability of the nervous system, while coffee has a destructive effect on it.
Cancer patients—drinking excessive coffee poses a cancer risk to normal people.
As coffee stimulates the role of the brain too strongly, directly affecting the state of mind, when coffee was first introduced to Europe in the sixteenth century, it was claimed that a doctor’s prescription is required to drink coffee. For four to five centuries, the vigorous development of the coffee culture has made people no longer have coffee without a day, but the medical community has continuously proposed that the impact of coffee on the human body is not only refreshing.
Let's talk about the refreshing effect of coffee. According to research, drinking 100-200 milligrams of caffeine per day is enough to refresh the body and harm the body. The best time to drink coffee is for an office worker to have breakfast in the early morning, just after arriving at the office, and after lunch break. Prepare for an afternoon of busy work. At this time, a cup of coffee will be able to get rid of the usual drowsy after dinner.
The study also found that for the average person, each cup of coffee in the morning and afternoon had the best refreshing effect. Exceeding this amount not only failed to achieve refreshing effect, but also made people feel restless.
Drinking too much coffee can also lead to the loss of calcium. For older people, especially middle-aged women, it is also a major threat to osteoporosis. Two or more cups of coffee a day will increase the probability of fracture by about 50%. It is startling. Experts believe that older people drink coffee and the cup is the safest one day.
