作用类似于腺苷,咖啡因阻隔了神经系统中的受体接收要降低能量消耗的信号。当这种情况发生时,大脑中的神经刺激物质——多巴胺和谷氨酸酯——的水平会上升,我们会体验到喝下一大杯爪哇咖啡后对大脑产生的刺激效果。
Seen this way, coffee may act as a mild antidepressant — at least to an extent. Previous research has found similar correlations reinforcing the possibility that coffee–the most frequently ingested psychoactive substance in the world–can help alleviate depression.
从这方面看,咖啡的作用可能像一种温和的抗抑郁剂,至少某种程度上是这样。之前的研究也发现了类似的相关性,进一步表明咖啡——这一世界上被最频繁摄取的精神活性物质——能够帮助缓解抑郁的可能性。
All of this research, however, should be taken with an enormous caveat that the findings are anything but conclusive. And given the drawbacks of cohort studies, it’s possible that the latest study results are a “mirage” that wouldn’t hold true outside of this particular correlative fishbowl.
然而,必须对这项研究审慎看待,该研究的结果决不是结论性的。鉴于群组研究的缺陷,这一最新研究结果很可能是个“幻像”,在这一特定研究之外,此种相关性很可能并不成立。
