这个研究的思路倒是挺有意思的，里面说之前的研究发现食品来源的黄酮类物质摄入和认知功能的改善有关（包括减少痴呆之类的），而黄酮类中有一类是黄烷醇，在可可、绿茶、红酒之类的里面都比较丰富，它们似乎有延缓甚至逆转随年龄增长的认知功能减退的作用。 但是讨论部分，作者自己也在解释不能说明这货是因果关系 “Of course, a correlation between X and Y does not prove causation but indicates that either X influences Y, Y influences X, or X and Y are influenced by a common underlying mechanism.” 最后还写了个纯属恶意卖萌的“研究局限性” STUDY LIMITATIONS The present data are based on country averages, and the specific chocolate intake of individual Nobel laureates of the past and present remains unknown. The cumulative dose of chocolate that is needed to sufficiently increase the odds of being asked to travel to Stockholm is uncertain. This research is evolving, since both the number of Nobel laureates and chocolate consumption are time-dependent variables and change from year to year. 总之这个东西不是什么正经的研究，看上去更像个玩笑吧。从他提到的机制来讲，即使黄烷醇类物质真的具有延缓认知功能减退的作用，也不代表会让人变得更聪明，更何况更聪明也未必会让人得诺奖。 参考资料[1]国家人均巧克力销量越大，诺贝尔奖得主越多，这是真的吗？ ApoE，果壳网果壳问答 |
