根据致癌作用的自由基理论,抗氧剂的抗癌作用是通过抑制致癌物在体内的氧化活化来完成的.实验证明,在一定条件下,天然抗氧剂维生素E、某些合成抗氧剂和硒(硒是过氧化物降解酶的成份)在动物体内有抗癌作用。抗氧化剂的抗癌作用可能通过抑制致癌物在体内的氧化过程,使潜在致癌物及协同致癌物如多不饱和脂肪酸趋于稳定,并可作为清除剂去除
According to the carcinogenic free radical theory, the anti-cancer effect of antioxidants is accomplished by inhibiting the oxidative activation of carcinogens in the body.Experiments show that under certain conditions, the natural antioxidant vitamin E, some synthetic antioxidants And selenium (selenium is a peroxide-degrading enzyme component) has an anti-cancer effect in animals. Anti-cancer effects of antioxidants may stabilize potential carcinogens and co-carcinogens such as polyunsaturated fatty acids by inhibiting the oxidation of carcinogens in the body and may be removed as scavengers
