Plos Med: 吃“不健康”食物,成“不健康”人...

2018-09-24 佚名 中国生物技术网

关于营养与癌症风险之间的联系一直是一复杂的话题。当然,很明显健康的食物要比不健康的食物更好。但是食物有多健康或不健康以及它的影响到底有多大是一直是一个难以量化的问题。考虑到这一点,英国食品标准局已经开发出一种营养素分析系统(FSAm-NPS),该系统正是为此而使用的。

首先,祝大家中秋快乐!

在这个大吃大喝的节日里,就给大家推送一篇关于“吃”的文章:一项新研究证实一个常识性观点,即如果你吃的不健康,那么你就有可能不健康,甚至患癌几率大增。

关于营养与癌症风险之间的联系一直是一复杂的话题。当然,很明显健康的食物要比不健康的食物更好。但是食物有多健康或不健康以及它的影响到底有多大是一直是一个难以量化的问题。考虑到这一点,英国食品标准局已经开发出一种营养素分析系统(FSAm-NPS),该系统正是为此而使用的。这个系统比较复杂,但实质上就是在给不同种类的食物打分。可以把它看作一种营养指数,几乎可以应用于所有的食物。发表在《PLOS Medicine》上的这项研究分析了这个分级系统,并发现了它在预测癌症发病率的出色性。该研究由法国国家卫生与医学研究所的Mélanie Deschasaux及其同事与世界卫生组织国际癌症研究中心合作完成。研究表明,使用基于FSAm-NPS的包装标识(比如Nutri-Score)对于促进消费者选择健康食品具有广泛的前景。

帮助消费者选择更健康的食品是预防癌症和其他疾病的关键问题。欧洲当局正在考虑实施一项独特的营养标签作为反映食品营养质量的体系,比如FSAm-NPS制定的五色Nutri-Score营养评分,目前在法国使用,最近也得到比利时政府的认可。FSAm-NPS评分体系与癌症风险之间的关系已经在很多国家和地区的人群中进行了研究,这项研究是针对全欧洲人口。

Deschasaux及其同事分析了来自欧洲癌症与营养前瞻性研究(EPIC, 1992-2014,中位数随访:15.3年)的471495名成年人的食物摄入数据,其中有49794名癌症患者,包括乳腺癌12063例、前列腺癌6745例和直肠癌5806例。研究人员们评估了每位参与者基于FSAm-NPS的饮食指数,并计算了多次调整的Cox比例风险模型,以描述FSAm-NPS饮食指数和癌症风险之间的关系。

在FSAm-NPS饮食指数高和低(以5分位法的5分和1分)的人群中,绝对癌症发病率分别为81.4和69.5例/万人年。研究人员发现,较高的FSAm-NPS饮食指数高(代表食品营养质量较低)与癌症整体风险增高之间存在关联。对于男性而言,较高的FSAm-NPS饮食指数尤其与直肠癌、上呼吸道、癌和肺癌相关;对于女性而言,则是肝癌和绝经后乳腺癌。该研究的主要不足之处在于使用了参与者自己报告的饮食数据,且只在基线时收集一次。

但研究人员仍表示,FSAm-NPS饮食指数适合作为食品包装前面的标签,也适合用于其他的公共卫生营养测量。”

说了那么多,其实就想表达:月饼别吃太多,别只顾满足口腹之欲,而懈怠了自己的健康!
