研究显示,硒是人类生命中必需的微量元素,与人类的生长、发育和健康有着密切的关系。如果人体缺少硒,容易导致各种疾病。肿瘤据医学调查表明,肿瘤的发生、死亡率与人体的硒水平呈负相关。硒具有抗氧化作用,能够阻止体内自由基的累积。由于体内的自由基在细胞癌变过程中起着重要作用,即自由基参与了诱发癌变和发展进程,所以,硒有预防癌症的作用。另外,科学研究揭示,硒不仅能有效降低致癌物质诱发的多种DNA的损伤,而且能促进DNA损伤的修复。由此
Studies have shown that selenium is an essential trace element in human life, and has a close relationship with human growth, development and health. If the body lacks selenium, easily lead to various diseases. According to the medical survey of tumors, tumor occurrence and mortality are negatively correlated with selenium levels in the human body. Selenium has an anti-oxidant effect that stops free radicals from accumulating in the body. Because of the body’s free radicals play an important role in canceration of cells, that is, free radicals are involved in the process of inducing carcinogenesis and progression, therefore, selenium has the effect of preventing cancer. In addition, scientific research reveals that selenium not only can effectively reduce the damage caused by carcinogen-induced multiple DNA, but also can promote DNA damage repair. thus
