许多人期望通过服用维生素来预防慢性病(如肿瘤等),而Vit-E、Vit-C是其中最常用的药物之一。一些大规模随机试验表明Vit-E可能会降低前列腺癌的发病风险,然而没有试验进一步证实这一可能,而且在人群中先前也没有试验明确vit-c可以单独预防恶性肿瘤。 Many expect to prevent chronic diseases (such as cancer) by taking vitamins, one of the most commonly used drugs. A number of large-scale randomized trials have shown that Vit-E may reduce the risk of prostate cancer. However, no further study confirms this possibility and no previous study in the population has demonstrated that vit-c alone can prevent malignancies.
