Coffee, usually considered a refreshing drink, because of work, I especially like to drink coffee, sometimes a person slowly tasting, sometimes a large sip, depending on their momentary interest. Drinking for decades, I have a special feeling for coffee, there are many benefits, I do not advertise for coffee, but I will tell you her benefits, it will certainly help. Coffee has the effect of improving the immune function of the body, and may have some anti-viral effect. I basically do not catch a cold, rarely rarely have a fever, may be related to long-term coffee drinking. So far there are no reports about coffee improving the body’s immune function, but I speculate that it may be related to coffee excites the central nervous system and plays a positive regulatory role on immune function. We know that some of the treatment of cold and flu drugs contain more or less caffeine, so once you feel particularly tired, or have a cold aura, or have a headache, runny nose, sneezing, drink a cup of hot coffee, both refreshing, but also to relieve the symptoms of khat, the most important thing is that there is no drug payment effect. Coffee has a protective effect on the liver China is a region with a high incidence of viral hepatitis, the reasons for which are related to geographical distribution, demographic factors, race, genes, hygiene habits, in addition to dietary patterns and habits. In Europe and America, the incidence of viral hepatitis is lower, especially hepatitis B. Personally, I do not rule out that it has something to do with their fondness for coffee. During my stay in the United States, every day when I arrived at the laboratory, I could smell the fragrant coffee, and as soon as my American boss came to work, the first thing he did was to make coffee (which might be a bit exaggerated). The lab lounge (for lunch) was equipped with an automatic coffee machine, and we often saw our foreign colleagues discussing problems while working and drinking coffee. I did a search on the internet to find out whether coffee has a protective effect on the liver, and there were several articles about coffee reducing the risk of cirrhosis and liver cancer. One of the studies from Japan found that Chinese green tea also has some effect, which may be related to the fact that green tea also contains a small amount of caffeine. A recent article from HEPATOLOGY (2010;51:201-209.), a leading American journal in the field of liver disease, discusses “Increased Caffeine Consumption Is Associated with Reduced Hepatic Fibrosis” (Increased Caffeine Consumption Is Associated with Reduced Hepatic Fibrosis), which does not elaborate on the mechanism by which coffee reduces hepatic fibrosis, but it should be plausible and an indisputable fact that this conclusion was reached through follow-up observations and statistical analysis of a large sample. It also coincides with what I have slowly experienced and felt over the years in my work. Coffee is both a favorite beverage, but also has such a magical effect, there is no pay effect, perhaps some friends say, I do not sleep well, can not drink, it is recommended that you drink in the morning or drink at noon, do not have to worry about coffee caused insomnia pay effect, drink more than a miracle, can improve sleep, remember, everything is possible! Told so much, it is better to act quickly, for your health, for your liver, drink more coffee it! Please believe: coffee is bitter, and life is sweet! By the way, I forgot to tell you all, what kind of coffee to choose? General commercially available instant coffee, coffee powder can be, but the best or coffee beans, freshly ground and boiled, not only to maintain the unique flavor of coffee, but also to avoid the intake of some additives, especially for some people who are fat or have hyperlipidemia, it is recommended to drink no sugar, partners, creamer “pure coffee” more appropriate, this unique bitter taste This unique bitterness really makes people aftertaste.
