绿茶因其含有抗氧化物质槲皮素和氨基酸茶氨酸,也能抵抗流感。多项实验表明,茶氨酸是抗病毒的潜在因素,能阻止很多呼吸道病毒复制,比如流感病毒。《药用食材期刊》(Journal of Medicinal Food )做过实验,发现茶氨酸可以在感冒病毒感染初期抑制病毒复制。
A study completed by researchers at University of Florida and the Nutritional Science Research Institute and published in the Journal of the American College of Nutrition found that L-theanine and decaffeinated green tea catechins are capable of boosting the body’s immune system. The results suggest that green tea can decrease the incidence and duration of cold and flu symptoms.
佛罗里达大学和营养科学研究院(Nutritional Science Research Institute)合作进行了一项实验,结果发表在《美国营养学院期刊》上。实验表明,茶氨酸和去咖啡因的绿茶儿茶酚都能提高人体免疫力。绿茶能降低感冒和流感症状发生的可能性,也能缩短症状周期。
“With this study, we were able to show that ingestion of a specific combination of decaffeinated tea polyphenols standardized to 45 percent EGCg and L-theanine, would enhance systemic immunity, and prevent cold and flu symptoms in healthy individuals. This is a significant finding,” said lead study author Susan S. Percival, PhD.
实验主创苏珊·S·皮思温博士说:“我们在这个实验中发现,摄入去咖啡因茶多酚中45%的茶多酚和儿茶酚,能够提高免疫力,帮助健康的人抵抗感冒和流感。这项发现意义重大。”
