In addition, a nonlinear relationship between tea intake and AD was reported by the association analysis, suggesting daily consumption of 5–6 cups to be the most protective and indicating possible increased risk effects for daily consumption of greater than 13 cups of tea.
最近看到一个关于茶与奥兹海默症的关系的新研究。
其中最有意思的一段是这样的：
In addition, a nonlinear relationship between tea intake and AD was reported by the association analysis, suggesting daily consumption of 5–6 cups to be the most protective and indicating possible increased risk effects for daily consumption of greater than 13 cups of tea.
每天五六杯茶降低失智风险，但是喝13杯以上，每增加一杯就增加一分风险。
问题是一杯茶是什么意思。
中国式喝茶，沏一杯浓茶，喝完续五次水，算六杯？

以前写过，看最后几段

但我一杯茶续13次以上的水是有的，最后完全没有茶味了。
这是好几个姓名是汉语拼音的人，根据“UK Biobank (N = 447,485), and AD was from the International Genomics of Alzheimer’s Project (N = 54,162).”里面的数据来做的分析研究。
既然是UK的数据库，那基本上就是英国人的饮茶习惯了。
英国式喝茶，不同于“中国式喝茶”，不但茶不一样，喝法也大相径庭。
