最近看到一個關於茶與奧茲海默症的關係的新研究。
其中最有意思的一段是這樣的:
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風險,但是喝13杯以上,每增加一杯就增加一分風險。
問題是一杯茶是什麽意思。
中國式喝茶,沏一杯濃茶,喝完續五次水,算六杯?
