摘要
目的了解吴江市公办小学和民工子弟小学的午餐营养素摄入状况。方法采用称量、记录相结合的方法对吴江市18所公办和民工子弟小学的午餐膳食营养素进行分析。结果公办小学午餐中维生素A仅占建议标准的32%;民工子弟小学午餐除热量和维生素C,其余均严重低于标准;公办小学午餐中蛋白质所占能量比为26%,超过标准;民工子弟小学午餐中蛋白质和脂肪来源能量分别为11%和12%,明显低于建议标准。公办小学和民工子弟小学午餐中动物食品所提供的钙、铁偏低。结论建议学校增加动物肝脏、动物全血等的供应来提供维生素A和吸收率高的铁。民工子弟小学学生多饮用牛奶,并且在学校午餐中增加价格相对便宜而营养价值较高的豆制品供应。政府部门应加强学生午餐营养方面的引导,加大资金投入。
