Is fresh coffee good for your health? Drinking too much is harmful

It is reported that Taiwan launched the "traffic light" of instant coffee in August this year, indicating that coffee shops should indicate the caffeine content of each type of coffee on the menu, with a green light of less than 100 mg, a yellow light of 100 to 200 mg, and a red light of more than 200 mg. It's best not to drink more than one cup a day. However, none of the major coffee shops in Hong Kong has disclosed the caffeine content of their coffee drinks, making it difficult for the public to make a healthy consumption choice.

As to whether Hong Kong will make reference to Taiwan's experience and encourage business operators to implement a similar "traffic light" system, the Fehd said that "this is not a food safety concern, but it is also a good thing for consumers to provide more information on food ingredients, and the Department welcomes it". The Consumer Council agrees that this is conducive to consumer rights and interests.

According to the EU Food Scientific Committee, caffeine affects the central nervous system, kidney and cardiopulmonary circulatory system. Li Jingyi, a registered dietitian of the Nutrition Research Center of the School of Public Health of the Chinese University of Hong Kong, and Liu Feilong, Director of the Hong Kong poisoning Counseling Centre, both pointed out that according to comprehensive medical literature, adult caffeine intake had better not exceed 300 to 400 mg.

Long-term excessive caffeine intake may lead to chronic caffeine poisoning before you know it, that is, "caffeine syndrome". Symptoms include mental tension, anxiety, handshake, muscle tension, insomnia, heart palpitations and so on. The cause is that the central nervous system is overly alert to the effects of caffeine. He agrees with the caffeine content of open drinks in coffee shops.
