摘要
在1982、1992和2002中国膳食调查数据的基础上,结合统计资料分析中国居民膳食的种类和数量,利用气相色谱测定食物脂肪酸含量,计算每日摄入膳食脂肪酸含量。结果表明,近20年来,中国居民膳食中摄入总脂肪酸含量显著升高,饱和脂肪酸的比例升高,而单不饱和与多不饱和脂肪酸的比例下降,胞和脂肪酸(SFA):单不饱和脂肪酸(MUFA):多不饱和脂肪酸(PUFA)为处于合理范围,但n-6/n-3变化不甚明显,在8.8:1~9.56:1之间,达不到较合适的比例。
Based on the national dietary survey in of Chinese food intake was analyzed. The fatty 1982, 1992 and 2002, the diversity and quantity acids were measured by GC--MS and used for further analysis. The results showed that the total fatty acid intake increased prominently. The SFA : MUFA : PUFA is changed from 1 : 1.5 : 1.4 (1982) to 1 : 1.4 : 1.05 (1992) and 1 : 1.3 : 1.1 (2002). The SFA : MUFA : PUFA was kept in a reasonable range. The n-6/n-3 in 8.8 : 1~9.56 : 1 was not in a reasonable range.
