【摘要】：基于28种果蔬消费量的基础数据(2003-2013年),借助R统计分析软件,采用等维灰数递补模型预测2016-2020年的果蔬消费量,分析不同果蔬的消费发展趋势.其次结合果蔬的消费量预测值估计我国居民未来5年膳食纤维、维生素和矿物质的摄入量,测算结果与《中国居民膳食营养素参考摄入量(DRIs)》中的平均需要量(EAR)作比较,结果显示,所有营养素的摄入量都在逐年增加;维生素A,抗坏血酸,铁和镁等微量元素的摄入量已经比较充足;维生素E和磷的摄入量逐渐达到合理范围;核黄素、锌、钙的摄入量占DRI的70%~80%;纤维和硫胺素的摄入量占DRI的60%~70%;硒的摄入量不足1/2DRI.表明我国居民的膳食营养结构存在一定程度失衡,在满足居民身体健康所需均衡营养的意义下,提出果蔬产业和居民营养均衡协同发展的调整战略.
[Abstract]:Based on the basic data of 28 kinds of fruit and vegetable consumption from 2003 to 2013, the consumption of fruits and vegetables from 2016 to 2020 was predicted by using the equal dimension grey number complementary model with the help of R statistical analysis software, and the trend of consumption of different fruits and vegetables was analyzed. Secondly, the estimated dietary fiber, vitamin and mineral intake of Chinese residents in the next 5 years were estimated by combining the predicted value of consumption of fruits and vegetables. The calculated results were compared with the average requirement in the reference dietary nutrient intake (DRIs) of Chinese residents. The results show that the intake of all nutrients is increasing year by year; the intake of trace elements such as vitamin A, ascorbic acid, iron and magnesium is more adequate; the intake of vitamin E and phosphorus gradually reaches a reasonable range; riboflavin, zinc, zinc, riboflavin, zinc, etc. Calcium intake accounted for 80% of DRI; fiber and thiamine intake accounted for 60% of DRI; selenium intake was less than 1 / 2 DRI. The results indicated that there was a certain degree of imbalance in the dietary nutrition structure of Chinese residents. In the sense of satisfying the needs of the residents' health balanced nutrition, the adjustment strategy of coordinated development of fruit and vegetable industry and residents' nutrition balance was put forward.
