每天喝一杯酒會增加癌症風險嗎？

【30秒重點】

• 不抽菸，喝酒維持在低風險範圍內或不喝。
• 英國研究追蹤23到55歲的人：一直在低風險指引內喝酒、而且不抽菸的人，整體健康最好。
• 但到55歲時，幾乎所有「不喝酒」的人其實是以前喝過、後來戒掉的。
• 所以少量喝酒看起來比較健康的結果，可信度被削弱。

Alcohol and Cigarette Use From Ages 23 to 55: Links With Health and Well-Being in the Long-Term National Child Development Study: Journal of Studies on Alcohol and Drugs: Vol 78, No 3

Conclusions:

British adults who consistently drank within new lower risk guidelines and abstained from smoking from young adulthood to midlife reported the best overall health and well-being across numerous indicators. However, apparent observed health benefits of stable low-dose alcohol use (vs. abstention) are weakened by the fact that by age 55 almost all alcohol “abstainers” in the National Child Development Study sample were former drinkers, and that respondents who followed infrequent drinking/abstention paths were the mostly likely to report poor health, psychological distress, and low educational qualifications in early adulthood.


Alcohol Consumption and Mortality From Coronary Heart Disease: An Updated Meta-Analysis of Cohort Studies: Journal of Studies on Alcohol and Drugs: Vol 78, No 3

Conclusions:

Pooled analysis of all identified studies suggested an association between alcohol use and reduced CHD risk. However, this association was not observed in studies of those age 55 years or younger at baseline, in higher quality studies, or in studies that controlled for heart health. The appearance of cardio-protection among older people may reflect systematic selection biases that accumulate over the life course.

Diet, nutrition, physical activity and breast cancer

簡單說：就算每天一杯，也會增加癌症風險。
