如果你認為，每周里有幾個夜晚喝上一杯葡萄酒對身體沒有什么壞處，請把它類比為抽上5至10支香煙。這是期刊《BMC公共衛生》（BMC Public Health）的一項新研究得出的結論。研究人員在其中將導致癌癥的惡習之一——吸煙與另一種惡習進行了對比。
不過這并不意味著飲用酒精就沒有缺點。美國國家癌癥研究所（National Cancer Institute）指出，美國衛生與公共服務部（U.S. Department of Health and Human Services）將飲用酒精列為了已知致癌因素，并認為它與乳腺癌、結腸癌、食道癌與肝癌都有關系。（財富中文網）
If you think a glass of wine a few nights a week can’t be that bad for your health, consider that it could be the healthy equivalent of smoking five to 10 cigarettes. That’s according to a new study published in the journal BMC Public Health, in which researchers looked at how one type of vice that causes cancer—smoking—compared with another.
The research focused on the absolute lifetime risk of drinking one bottle of wine a week. Absolute risk, as defined by the Mayo Clinic, is how likely a person is to develop a condition over their entire life. So for example, on average, American men have a 12% absolute risk of developing prostate cancer, meaning 12 out of 100 will develop the cancer, and 88 out of 100 men will not.
In the case of drinking a bottle of wine every week, non-smoking men’s absolute risk increased 1%, or roughly the equivalent of smoking five cigarettes. In non-smoking women, the absolute risk rose 1.4%, the equivalent of smoking 10 cigarettes, with a 0.8% absolute risk of breast cancer. In other words, depending on an individual’s other risk factors and lifestyle choices related to their likelihood of developing cancer, drinking that much wine could further elevate their risk rate.
The link between cancer and using tobacco products and smoking is relatively well understood, but when it comes to drinking, the study authors noted that the risks of even somewhat moderate alcohol consumption are often a little less obvious to the public.
But that doesn’t mean that drinking alcohol doesn’t have its drawbacks. The National Cancer Institute notes that the U.S. Department of Health and Human Services lists the consumption of alcohol as a known human carcinogen and accordingly, it is linked to various cancers including those of the breast, colon, esophagus, and liver.
