浙江省城市居民膳食营养摄入状况研究

目的了解浙江省城乡居民膳食营养摄入现状。方法 2008年根据不同经济水平、不同饮食习惯及地理分布,选择浙江省11个城市,以连续3 d 24 h回顾法为基础,3 d秤重法为补充收集居民膳食数据。结果膳食调查共4 949人。蛋白质(84.9 g/标准人日)、能量(9 653.7 kJ/标准人日)基本满足要求,谷类食物仍是膳食主体,优质蛋白质摄入有所改善,猪肉占的比例较高(75.5%),豆类摄入增加(36.2 g/标准人日);脂肪摄入量提高很快,达到87.7 g/标准人日;脂肪供能占总体供能的比例迅速提高,达到34.3%,已超过WHO的上限值(30.0%);油脂和食盐摄入量分别为41.3 g/标准人日、10.5 g/标准人日,高于推荐值;水果和部分微量营养素(如钙、膳食纤维等)摄入不足,奶制品摄入水平仍然偏低,仅有60.0 g/标准人日。结论浙江省城市居民膳食结构模式比较合理,但已出现高蛋白、高盐、高脂肪的趋势,部分营养素摄入不足,应加强营养知识教育普及,提倡合理膳食和健康的生活方式。
