E\u011fer DNA do\u011fru bir \u015fekilde kopyalanmazsa, yanl\u0131\u015f ve bozuk DNA elde edilir bu da genlerin genel yap\u0131s\u0131nda bir bozuklu\u011fa yol a\u00e7ar. Bu bozukluklar da \u00e7e\u015fitli kanserlere neden olur.\u00a0 Kanser riskini azalt\u0131yor.<\/p>\n
\u00c7ay\u0131n, flavinoid denilen anti oksidanlar a\u00e7\u0131s\u0131ndan zengin oldu\u011fu \u00f6teden beri bilinmektedir.
