Ever since coffee was discovered by humans in the 15th century, health devotees of different eras and nationalities have tirelessly exhorted lovers of this dark beverage to give up their "vice." Unfortunately, all this has been in vain. They do so,无非是 following the creed of some: whatever brings joy to people must be harmful to health.
The first coffee ban on the grounds of being "unhealthy" was issued in Mecca in 1511. However, due to an expert opinion reaching the opposite conclusion and the emergence of a coffee-loving Sultan, the ban was lifted. In Turkey in 1633, drinking coffee could even be punishable by death. But even so, it was to no avail, and various punishments were gradually replaced by taxes, with the tax targets being coffee houses. In Europe, as this beverage became all the rage, physicians also condemned this dark drink. Dr. Colom of Marseilles issued a medical judgment on coffee in 1679. He believed that these roasted black beans would dehydrate the kidneys, nerves, and brain, and he predicted that this would eventually lead to exhaustion, muscle paralysis, and even impotence.
Even today, the "harmful" ghost of coffee is still cursed. Arno Dominé, president of the Society for Naturopathic Medicine, pointed out in 1995 that coffee burdens the adrenal glands and obstructs subcutaneous blood circulation. It makes the nervous system restless, causing people to sweat under their arms and frequently have diarrhea. And even more terrifyingly, he believed that whoever does not experience these symptoms "whose nervous system has already become completely numb." How awful!
A small medical encyclopedia rather vaguely states that coffee must at least bear joint responsibility for these tormenting dysfunctions. The book's accusations against coffee are extensive, ranging from metabolic disorders, gastrointestinal and liver diseases, to heart and vascular ailments and rheumatism. In addition, coffee will (of course!) cause cancer. But where is the evidence?
With the exception of alcohol, no other beverage has been studied so carefully and frequently by nutritionists as coffee. We always hear accusations that coffee increases the incidence of myocardial infarction. This impressive causal relationship was first discovered in a Norwegian study, although the reasons were not explained, but in Germany, the advice "don't drink coffee" immediately spread like wildfire. But six years later, Norwegian scientists announced they were retracting their conclusion, because the relationship between coffee and myocardial infarction, after careful calculation, completely disappeared.
Today, based on the results of numerous experiments, it has been proven that coffee neither causes myocardial infarction and stroke, nor induces gout and diabetes. On the issue of cancer, the World Cancer Research Foundation, based on an assessment of countless current studies, believes that coffee does not increase the incidence of cancer. Only in observations of bladder cancer was it found that coffee might slightly increase the risk of this type of cancer. But when observed in conjunction with smoking, the link between coffee and bladder cancer is found to be much weaker than that between smoking and it.
Another new conclusion was discovered in this experiment. For obvious reasons, many people are unwilling to say much about it. This conclusion is: after heavy drinking, coffee may have a protective effect on the liver, reducing adverse consequences. Not only are regular coffee drinkers less likely to suffer from cirrhosis, but these people also have higher liver function indicators (GGT).
So, before experts finally decide to recommend that everyone drink coffee, we might still only be able to sip one or two small cups of coffee.
