河南省三市郊区居民营养状况评价

The evaluation of the nutritional status of the residents in 3 Henan suburbs

对三市郊区居民87户306人3 d称重法膳食调查,发现蛋白质、碳水化物、热能、铁、维生素B_1、PP、C的摄入量接近或达到供给量标准,而脂肪、钙、维生素A、B_2摄入量不足。生化检测结果显示,三市郊区健康成年人(90例)体内血红蛋白、血清总蛋白、胆固醇、锌、铜、铁含量达到生理需要,而血清钙、维生素B_1、B_2含量在不同地区人群间存在不同程度的不足。提示膳食结构应做进一步调整,以满足居民各种营养素的需要。
