What is moderate drinking?

Moderate drinking refers to reasonably controlling alcohol intake within a certain range to reduce health risks and possibly obtain small benefits. The World Health Organization (WHO) and health agencies in various countries generally recommend that men’s daily alcohol intake should not exceed 25 grams (about 2 glasses of beer or 1 glass of wine), and women should not exceed 15 grams. Excessive drinking can cause health problems such as liver disease and cardiovascular disease, while abstaining from alcohol altogether or drinking in moderation may have certain positive effects on social and mental health. This article will start from four aspects: scientific definition, health effects, precautions and common misunderstandings to help readers establish a rational concept of drinking.

Scientific Definitions and Standards

The core of moderate drinking lies in the definition of "quantity". According to the "Dietary Guidelines for Chinese Residents" from the Chinese Nutrition Society, daily alcohol intake should be ≤25 grams for adult men and ≤15 grams for women, which is equivalent to 750 ml of beer, 250 ml of wine, or 50 ml of liquor. The alcohol content of different wines varies greatly (see table below), so please pay attention to the conversion. The U.S. CDC emphasizes that "moderate drinking" should be based on individual physique, such as weight, metabolic capacity, etc. In addition, pregnant women, teenagers and people with liver disease should avoid drinking alcohol altogether.

The dual nature of health effects

Moderate drinking may provide modest benefits, such as the polyphenols in red wine that may help cardiovascular health (more research is needed). However, the World Health Organization points out that alcohol is a clear carcinogen, and even small amounts may increase the risk of oral cancer, breast cancer, etc. Short-term overdose can lead to drunkenness and liver damage, while long-term overdose is closely related to liver cirrhosis and hypertension. The Harvard School of Public Health recommends that if it is not necessary, it is best to choose zero alcohol intake, because there is no absolute standard for "safe drinking amount".

Things to note and common misunderstandings

When drinking alcohol, avoid taking it on an empty stomach, mixing alcohol with alcohol, or taking medicines together. Common misunderstandings include "drinking to warm up" (actually dilation of blood vessels leads to heat loss) and "red wine to maintain health" (need to limit it to a small cup a day). Some manufacturers, such as Changyu and Tsingtao Beer, have launched low-alcohol products, but consumers still need to refer to the alcohol content on the label. The China Alcoholic Drinks Association reminds you not to believe exaggerated propaganda such as "moderate drinking can cure diseases".

Practical advice on responsible drinking

Taken together, the key to moderate drinking is self-control and scientific understanding. You can choose low-alcohol alcohol, drink with food, and monitor liver function regularly. In social situations, non-alcoholic beverages can be substituted. If you have any health concerns, it is recommended to consult a doctor. Remember, alcohol is not a necessity, a healthy lifestyle is fundamental.
