The National Institute of Alcohol Abuse and Alcoholism recently pointed out that moderate drinking is good for some people, but people should consult their doctors about the amount of alcohol that suits them, and then use it as a way to keep healthy. This study summarizes and analyzes the scientific literature about drinking and health, and draws the conclusion that alcohol can not be simply said to be beneficial or harmful to health, and drinking has both advantages and disadvantages. Compared with abstainers or alcoholics, moderate drinkers are less threatened by heart disease, but alcohol also has disadvantages such as unfavorable wound healing and increasing the incidence of breast cancer and liver disease. Generally speaking, the advantages of moderate drinking outweigh the disadvantages, but the benefits vary from person to person. People over 40 are more or less threatened by heart disease, so moderate drinking will benefit them more, while young people will benefit little. It can be seen that drinking one or two glasses of wine every day can not nourish everyone. Samir, one of the authors of the research report, pointed out that there is no uniform standard for healthy drinking, and drinkers should ask doctors for specific suggestions according to their age, gender and overall health status. According to the website of the British magazine Nature, this research result is likely to be the basis of the health guidelines issued by the US government next year. However, some experts believe that instead of arguing about the standard of moderate drinking, it is better to publicize the knowledge of healthy drinking to drinkers. For example, the label of wine should be printed with a suggestion that it should not exceed one or two glasses a day, or the bar staff should remind customers not to drink too much.
