科克大学APC微生物研究所的研究团队在《自然通讯》上发表的最新研究表明，咖啡因和无咖啡因咖啡都能改变肠道微生物群，进而通过肠脑轴影响人体的情绪、压力反应、记忆和注意力1。该研究对62名参与者进行了对照试验，其中包括31名定期咖啡饮用者和31名非饮用者1。研究发现，咖啡饮用者在停用咖啡两周后，肠道代谢物出现显著变化；重新摄入咖啡后，参与者的压力和抑郁感随之降低1。
含咖啡因和无咖啡因咖啡在对大脑功能的影响上存在差异1。无咖啡因咖啡与学习和记忆改善相关，而含咖啡因咖啡则与焦虑减少和注意力改善相关1。此外，两种咖啡都与压力、抑郁和冲动性的降低相关1。根据欧洲食品安全局的标准，日均3-5杯被定义为安全适度的咖啡摄入量1。该研究由国际咖啡科学信息研究所赞助1。
Researchers from University College Cork's APC Microbiome Institute have published findings in Nature Communications demonstrating that both caffeinated and decaffeinated coffee alter the composition of gut microbiota and influence brain function through the gut-brain axis 1. The controlled trial involved 62 participants—31 regular coffee drinkers and 31 non-coffee drinkers—who were monitored to assess how coffee consumption affects mood, stress, memory, and attention 1.
The study showed that when regular coffee consumers stopped drinking coffee for two weeks, significant changes occurred in their intestinal metabolites 1. Upon resuming coffee intake, participants experienced reduced stress and depression symptoms 1. The research revealed distinct benefits depending on coffee type: decaffeinated coffee was associated with improvements in learning and memory, while caffeinated coffee correlated with decreased anxiety and enhanced alertness and attention 1. Both varieties of coffee were linked to lower levels of stress, depression, and impulsivity 1.
According to European Food Safety Authority standards, the researchers defined safe moderate coffee consumption as three to five cups daily 1. The study was sponsored by the International Scientific Information Institute for Coffee (ISIC) 1.
