为了正确引导集体学龄前儿童合理膳食和提高营养水平,我们采用记帐法对山东外经委幼儿园进行了6年膳食调查,同时检测了在园儿童的部分生长发育指标.结果显示,该园儿童的热能摄入量范围是6.56～7.23mj/d,均超过供给量标准的100%,可以满足儿童的生长发育需要.但三大营养素的供热比不甚合理,脂肪供热比过高(范围:36.77%～46.13%),且呈逐年上升的趋势(r=0.96,P<0.001).蛋白质的摄入量均达到供给量标准,优质蛋白质(动物类蛋白和豆类蛋白)的百分比分别是 36.65%,42.12%,49.01%,52.91%,45.77%,56.41%,年均增长率为10.77%,无机盐中铁1991～1996年的摄入量均超过了供给量标准的80%,但Ca的摄入量.1996年最高,也仅占供给量标准的60.25%,锌1991～1996年的摄入量均低于供给量标准
In order to properly guide the reasonable preschool children’s diet and improve the nutrition level, we conducted a 6-year dietary survey by using the accounting method in Shandong KFF nursery school and detected some of the growth and development indicators of children in the park.The results showed that the children’s Thermal energy intake range is 6.56 ~ 7.23mj / d, are more than the supply of 100% of the standard, can meet the growth and development needs of children, but the three nutrients is not reasonable heating, fat heating is too high (range : 36.77% ~ 46.13%), and showed an increasing trend year by year (r = 0.96, P <0.001) .The intake of protein reached the supply standard, and the percentages of high quality protein (animal protein and pulse protein) 36.65%, 42.12%, 49.01%, 52.91%, 45.77%, 56.41% respectively, with an average annual growth rate of 10.77%. The intake of inorganic salts from 1991 to 1996 exceeded the supply standard by 80% Intake in 1996, the highest, only 60.25% of the standard supply, zinc intake in 1991 to 1996 were lower than the supply standards
