Western-style diets are associated with an increased risk of colorectal cancer (CRC). In particular, a strong correlation has been documented between CRC and the consumption of large amounts of red meat, especially processed red meat. Compared with white meat, red meat contains high levels of haem iron, a molecule that can exert a variety of genotoxic and other adverse effects on the colonic epithelium. According to current international guidelines, the reduction of red meat intake combined with the consumption of food containing antioxidant and chemoprotective substances may significantly reduce the risk of developing CRC. The dietary strategies that can help to contrast the harmful effects of haem iron are reported and discussed in this review.
西式饮食与结直肠癌(CRC)的风险增加有关。特别是,已经有大量文献证明 CRC 与大量食用红色肉类(尤其是加工过的红色肉类)之间存在很强的相关性。与白色肉类相比,红色肉类含有高水平的血红素铁,这种分子会对结肠上皮细胞产生多种遗传毒性和其他不良影响。根据当前的国际指南,减少红色肉类的摄入,同时食用含有抗氧化剂和化学保护物质的食物,可能会显著降低患 CRC 的风险。本文综述了有助于对抗血红素铁有害作用的饮食策略,并对其进行了讨论。
