Antioxidants maintain redox homeostasis and prevent ROS-/RNS-induced damages that have been associated with cancer development. In the body, antioxidant defence systems include endogenous (enzymatic and non-enzymatic antioxidants) and exogenous antioxidants supplied by plant foods. Antioxidants are widely used to protect cells from damage induced by reactive oxygen species (ROS). The concept that antioxidants can help fight cancer is deeply rooted in the general population, The most common natural antioxidants are antioxidative enzymes [ 10] whereas others are well represented in different spices and herbs [ 11 ].

The purpose of this review is to survey the literature on modern biological theories of cancer and the roles of dietary antioxidants in cancer. The roles and functions of antioxidant micronutrients, such as vitamin C (ascorbate), vitamin E (alpha-tocopherol), selenium, and vitamin A, provided through diet for the prevention of cancer are discussed in the present work. For cancers of the colon, breast, and prostate, the current data do not support a protective effect of antioxidants. More definite conclusions about the benefits of antioxidants in cancer prevention will be derived from on-going intervention trials. PMID: 8522720 [Indexed for MEDLINE] Publication Types: Review; MeSH terms. Antioxidants/therapeutic use* This review presents an extensive analysis of the key findings from studies on the effects of dietary antioxidants such as tea polyphenols, curcumin, genistein, resveratrol, lycopene, pomegranate, and lupeol against cancers of the skin, prostate, breast, lung, and liver.
