摘要
目的研究儿童膳食中脂肪和脂肪酸的食物来源分布,为儿童肥胖及其慢性病的预防提供资料。方法共有6 826名7-17岁被调查者完成膳食调查。通过连续3 d 24 h回顾法记录食物数据及称重法记录家庭调味品消费量数据,获得平均每人每日各种食物的摄入量。根据食物成分表计算平均每人每日膳食中脂肪和脂肪酸的摄入量。结果每天儿童膳食脂肪摄入量平均为67.4 g,饱和脂肪酸、单不饱和脂肪酸和多不饱和脂肪酸摄入量分别为16.4,26.5和16.4 g,比例为1.0∶1.6∶1.0。饱和脂肪酸的主要食物来源为肉类,占35.4%;其次为植物油和动物油,各占24.4%和21.3%。单不饱和脂肪酸的主要食物来源是植物油,占43.8%。结论儿童肥胖及高血压、糖尿病等慢性疾病的增加与饱和脂肪酸的过多摄入有关,肉类是饱和脂肪酸的主要食物来源,应该适当控制。
