为什么老爱喝抹茶,可能是为了缓解焦虑!

2019-07-29 佚名 细胞

很多国家都有茶文化,日本抹茶在世界范围内越来越受欢迎。在日本,抹茶有着悠久的药用历史。人们一直怀疑它对健康有各种有益的影响,但只有相对较少的科学证据支持这种说法。如今,熊本大学的一组日本研究人员发现,食用抹茶粉或抹茶提取物后,老鼠的焦虑行为有所减少。它的镇静作用似乎是由于激活多巴胺D1受体和血清素5-HT1A受体的机制,这两者都与焦虑行为密切相关。

很多国家都有茶文化,日本抹茶在世界范围内越来越受欢迎。在日本,抹茶有着悠久的药用历史。人们一直怀疑它对健康有各种有益的影响,但只有相对较少的科学证据支持这种说法。如今,熊本大学的一组日本研究人员发现,食用抹茶粉或抹茶提取物后,老鼠的焦虑行为有所减少。它的镇静作用似乎是由于激活多巴胺D1受体和血清素5-HT1A受体的机制,这两者都与焦虑行为密切相关。

抹茶是一种由生长在阴凉处(90%阴凉处)的中国茶树的新叶子磨成的细粉。茶(和食物调味料)在世界各地都很受欢迎。在日本,抹茶的历史药用价值包括帮助人们放松、预防肥胖和治疗皮肤疾病。因此,研究人员试图确定它的各种有益作用。

"高架加迷宫"测试是一个高架、加长形、狭窄的平台,有两个有墙的手臂,为测试对象(通常是老鼠)提供了安全保障。它被作为一种对啮齿类动物的焦虑测试,其理念是,经历更高焦虑的动物会在更安全的围栏区域待更长时间。通过这项测试,研究人员发现,食用抹茶粉或抹茶提取物后,老鼠的焦虑程度有所降低。此外,当评价不同抹茶提取物的抗焦虑活性时,与仅从热水中提取的提取物相比,80%乙醇提取的提取物具有更强的抗焦虑活性。换句话说,水溶性差的抹茶成分比易溶于水的成分具有更强的抗焦虑作用。行为药理学分析进一步揭示抹茶和抹茶提取物通过激活多巴胺D1和血清素5-HT1A受体来减轻焦虑。

研究负责人Yuki Kurauchi博士说:"虽然还需要做进一步的流行病学研究,但我们的研究结果表明,抹茶作为一种药物已经使用多年,它可能对人体有益。我们希望我们对抹茶的研究能给全世界的健康带来益处。"参考资料:
