咖啡对皮肤到底是有害还是有益

的确，喝咖啡好坏参半，但是根据哈弗大学公共卫生学院一项为时22年的研究，发现每天3~5杯的咖啡总的来说对身体还是有益的。
Coffee consumption has been shown to have minimal or no impact, positive or negative, on cancer development;[82] however, researchers involved in an ongoing 22-year study by the Harvard School of Public Health state that "the overall balance of risks and benefits [of coffee consumption] are on the side of benefits."[82] Various other studies have shown apparent reductions in the risks of Alzheimer's disease, Parkinson's disease, heart disease, diabetes mellitus type 2, cirrhosis of the liver,[83] and gout. A longitudinal study in 2009 showed that moderate drinkers of coffee (3-5 cups per day) had lower chances of developing dementia, in addition to Alzheimer's disease

虽然自己知道的也是道听途说,
但有一点自己是坚信的,
就是决无害.

因为本人自己就是咖啡爱好者,
自己的很多中外客户也都是咖啡爱好者,
年龄段从三十几岁到六十几岁的男女老少都有,
皮肤都一级棒就是最好的解释.
