    摘要:

    目的 以河南省肉及肉制品中铜为例,演示采用简单分布评估方法,评价河南省居民肉及肉制品饮食中铜摄入情况及其潜在的健康风险。方法 2014—2015年在河南省16个省辖市随机采集肉及肉制品309份,按照食品中铜测定的原子吸收光谱法标准操作程序进行检测,结合河南省2010—2012年开展的居民营养与健康状况监测中肉及肉制品的消费量数据,采用简单分布模型(确定性评估)方法,借鉴文献发表的肉及肉制品对膳食中铜的贡献率,计算河南省不同年龄组人群全膳食中铜摄入水平及其潜在的健康风险。结果 肉及肉制品中铜的平均含量为0.556 mg/100 g,中位数为0.060 mg/100 g,不同肉及肉制品中铜平均含量最高为内脏(1.561 mg/100 g),铜平均含量最低的为猪肉(0.068 mg/100 g)。河南省居民每天通过进食肉及肉制品的铜平均摄入量为0.046 mg/d,高端(P95)摄入量为0.144 mg/d。利用文献报道的肉及肉制品贡献率外推全膳食中铜摄入量后发现,河南省居民全膳食中铜的平均和P95摄入量分别为0.638和1.977 mg/d。个体评估结果显示,全人群铜摄入量处于推荐摄入量(RNI)与可耐受最高摄入量(UL)之间的个体比例为21.12%(801/3 792),处于EAR和RNI之间的个体比例为8.10%(307/3 792),而低于平均需要量(EAR)、大于UL的人群比例分别为69.75%(2 645/3 792)和1.03%(39/3 792)。结论 河南省全人群膳食中铜摄入量缺乏的风险较高,铜过量的风险较低。

    Abstract:

    Objective Taking the content of copper in meat and meat product in Henan Province as an example, to demonstrate how to evaluate the dietary intake of copper from meat and meat product and its potential health risks in Henan population using the simple distribution assessment method. Methods 309 meat and meat product were randomed collected in 16 cities in Henan Province from 2014 to 2015. The copper contents were detected according to National Food Contamination and Harmful Factors in Risk Monitoring Manual. Using the published contribution rate of meat and meat products to dietary copper for reference, the dietary intake of copper in Henan population was evaluated by simple distribution model method with the 2010-2012 Chinese nutrition and health surveillance data. Results The mean concentration of copper in meat and meat product was 0.556 mg/100 g, and the median of that was 0.060 mg/100 g, the mean concentration of copper in entrails (1.561 mg/100 g) was the highest, while that in pork (0.068 mg/100 g) was the lowest. The mean and high level (P95) daily intake of copper from meat and meat product by Henan population were 0.046 and 0.144 mg/d, respectively. The copper intake from meat and meat product was adjusted to the copper intake from the full diet using a published data, and the result showed that the mean and P95 daily copper intakes from the full diet were 0.638 and 1.977 mg/d, respectively. The individual copper intake assessment result showed that 21.12% (801/3 792) of the population had a diet copper intake between recommended nutrient intake (RNI) and tolerable upper intake level (UL), 8.10% (307/3 792) of the population had a diet copper intake between estimated average requirement (EAR) and RNI, 69.75% (2 645/3 792) of the population had a diet copper intake below EAR, only 1.03% (39/3 792) of the population had a diet copper intake over UL. Conclusion There was a high risk of dietary copper deficiency in the whole Henan population, while the risk of excess dietary copper was very low.
