不可以,维生素E过量能致癌
近年来,维生素E特别受中老年人的宠爱,他们用维生素E防治心脑血管疾病、防癌抗癌和抗衰老,但该药并非多多益善。
适量服用维生素E有抗癌作用,但如果摄入过量的维生素E反而有诱发癌症的可能性。这一重大发现是由日本三重大学医学院的川西正佑教授领导的研究小组经过长期的研究证实的。川西教授
他们在白血病患者的细胞里加入相当于正常血液10倍量的维生素E,经过培养,发现DNA里有与
致癌有关的损伤。川西教授指出,维生素E致癌的原因是由于维生素E形成的氧化物损伤了两种构成DNA的胸腺嘧啶和胞嘧啶。美国国立癌症研究所以29000名吸烟者为对象进行了临床试验,摄入β胡罗卜素(体内可转化成维生素A)肺癌的发生率却上升了18%;服用维生素E却使前列腺癌和直肠癌的发生率下降了。但在试验中也发现,维生素E与β胡罗卜素相同,有抑癌和致癌双重作用,关键在于摄入量的多少。川西教授说:“不能否认维生素E有抑制癌症的作用,但摄入量过多将会产生副作用,有可能诱发癌症。希望那些认为服用维生素E越多越好的人,特别注意遵照医嘱。”我国学者认为,服用维生素E不宜超过每日3次,每次100毫克
病情分析:
你好,你的这种情况是可以服用维生素E胶丸的。
指导意见:
根据你的叙述,你的这种情况可以服用维生素E,因为做了次囊肿手术,可以长期服用维生素E。
不可以,过量补充维生素E会致癌。
美国科罗拉多大学癌症研究中心的癌病专家拜尔斯及其团队,查阅30年间的相关文献,并对维他命E、β-胡萝卜素和叶酸3种最普遍的非处方药片或补充剂进行研究。结果发现,每天摄入过量的维他命补充剂,反而可能弄巧反拙,增加患癌风险高达56%。
这只是一项前瞻性研究,只能说明对于维生素等膳食补充剂的作用和机制,还需要进一步的研究,不要盲目添加。
在中国西部地区,主要针对当地食道癌发病率较高的问题,所以膳食补充胡萝卜素。结果一段时间后,研究人员发现,食道癌的发病率有所下降,可肺癌发病率却高了起来。
