由美国国家癌症研究所(NCI)和芬兰国家公共卫生研究所进行一项研究证实:维生素E能减少参与试验的芬兰男性吸烟者前列腺癌发病率。芬兰α-生育酚、β-胡萝卜素癌症预防研究(即著名的ATBC研究)显示,日服50mg α-生育酚参试者与未服用者相比,前列腺癌发病率下降32％。α-生育酚是维生素E最主要组份。另外,在试验期间,在接受α-生育酚试验男人中死亡率降低42％。所用维生素E剂量约为美国推荐规定准许服用量3倍。
A study conducted by the National Cancer Institute (NCI) and the Finnish National Institute of Public Health confirmed that vitamin E can reduce the incidence of prostate cancer in Finnish male smokers who participated in the trial. The Finnish α-tocopherol and β-carotene cancer prevention studies (known as the ATBC study) showed that the incidence of prostate cancer decreased by 32% when compared with those who did not take 50 mg of α-tocopherol. Alpha-tocopherol is the most important component of vitamin E. In addition, there was a 42% reduction in mortality among men receiving alpha-tocopherol during the trial. The dose of vitamin E used is approximately 3 times the amount recommended in the United States.
