蔬果中的槲皮素(Quercetin)有抗癌 作用
Quercetin’s Anti-Carcinogenic Properties
槲皮素(Quercetin)是一种天然的黄酮类化合物,存在于多种植物的花、叶、果实中,具有抗炎、抗氧化、清除氧自由基、抗粘附、抗血栓、抗病毒、抗肿瘤、降血糖、降血脂、降低血压以及免疫调节作用。
槲皮素在某些研究中还被发现可以治疗和预防癌症。2009年6月11日的《实验与临床癌症研究杂志》(Journal of Experimental and Clinical Cancer Research)显示,槲皮素被发现可以预防肝癌细胞的形成,主要是由于它作为一种抗氧化剂的作用。在2009年5月18日的医学杂志《植物疗法研究》中,槲皮素还被发现可以通过引起细胞凋亡或“细胞死亡”来治疗癌症。
虽然这些研究很有希望,但大多数都是在老鼠和老鼠身上进行的,而不是在人类身上。
美国癌症协会(ACS)报告了一项人类研究,其中槲皮素和姜黄素(Curcumin)的结合可以减少直肠肿瘤的大小和数量。美国癌症协会的立场是,他们希望在推荐补充剂之前,能看到更多关于槲皮素对人类癌症影响的临床试验。然而,他们确实通过增加每天新鲜水果和蔬菜的摄入量来增加槲皮素的摄入量。
含槲皮素的蔬果包括:苹果皮、莲藕、洋葱、蓝莓、越橘、黑莓、菠菜、豆角、柑橘等。获取槲皮素的最好方式是榨汁。

Quercetin’s Anti-Carcinogenic Properties
Quercetin has been found to both treat and prevent cancers in certain studies. The June 11, 2009 issue of the "Journal of Experimental and Clinical Cancer Research" showed that quercetin is found to be protective against the formation of liver cancer cells, mainly due to its role as an antioxidant. Quercetin is also found to treat cancer by causing apoptosis, or "cell death," as reported in the May 18, 2009 edition of the medical journal, "Phytotherapy Research." While these studies are promising, most have been performed on mice and rats but not on humans. The American Cancer Society (ACS) reports a human study in which the combination of quercetin and curcumin supplements decrease the size and quantity of rectal tumors. The stand of the ACS is that they would like to see more clinical trials on the effects of quercetin on cancer in humans before recommending supplements. However, they do promote adding quercetin to the diet by increasing your daily intake of fresh fruit and vegetables.
