AJCN:地中海饮食或可降低结直肠癌的发病率

2020-07-27 Zhao Lei MedSci原创

地中海式饮食是居住在地中海地区的居民所特有的,意大利南部和希腊为代表的饮食习惯,它并不是一种特殊的饮食计划或饮食过程,而是一种营养学家所推荐的膳食模式。

     地中海式饮食(Mediterranean dietMD)是居住在地中海地区的居民所特有的,意大利南部和希腊为代表的饮食习惯,它并不是一种特殊的饮食计划或饮食过程,而是一种营养学家所推荐的膳食模式。最少有16个国家属于地中海地区,但是因这些国家的文化、种族背景和宗教信仰的不同其饮食模式也不尽相同。但是,其在不同中却有着许多共同的特征。欧洲食品信息委员会(The European Food Information Council, EUFIC)指出:地中海式饮食是指有利于健康的,简单、清淡以及富含营养的饮食。这种独特的饮食结构强调多吃蔬菜、水果、鱼、海鲜、豆类、坚果类食物,其次才是谷类,并且烹饪时要用植物油(含不饱和脂肪酸)来代替动物油(含饱合脂肪酸),尤其提倡食用橄榄油。地中海式饮食以自然的营养物质为基础,包括橄榄油、蔬菜、水果、鱼、海鲜、豆类,加上适量的红酒和大蒜,再辅以独特调料的烹饪方式。

     越来越多的流行病学研究显示地中海饮食(MD)依从性与结直肠癌(Colorectal cancer,CRC)发病率和死亡率之间呈负相关。近日,发表在《The American Journal of Clinical Nutrition》的一项Meta分析就地中海饮食(MD)与结直肠癌(CRC)的发病率和死亡率之间的关系进行了进一步研究。该项Meta分析分别从PubMed,Embase和Web of Science进行文献搜索,分析截至2019年9月的合格研究。使用随机效应模型估算总RR值(Risk ratio)和95%置信区间(95%Confidence interval)。研究共纳入13项前瞻性队列研究,其中9项研究报告了结直肠癌的发病率,5项研究报告了结直肠的死亡率。研究发现,与低MD依从性相比,高MD依从性的人群CRC发生率降低了13%。有趣的是,未发现地中海饮食(MD)依从性与结直肠癌(Colorectal cancer,CRC)死亡率相关。

     最后,该研究指出需要在更广泛的地理区域中进行地中海饮食的依从性与结直肠癌患病风险和死亡率之间关系高质量研究,以检验该结论。
