中国不同地区膳食脂质摄入量的分析

１９９２年中国总膳食研究在１９９０年的基础上做了适当的改进,将城市和农村的样品分别进行分析。本文报道了该项研究中膳食脂质部分的结果（包括总脂肪、胆固醇、脂肪酸）。除南方二区外,同一地区的城市和农村居民在脂肪、胆固醇的摄入量上有较大的差异。北方二区农村居民的脂肪摄入量明显不足,而北方一区城市居民脂质的摄入量较高,胆固醇摄入量已超过每人每日３００ｍ ｇ 的水平。南方居民膳食脂肪中多不饱和脂肪酸所占比例低而单不饱和脂肪酸所占比例高。基于以上分析,作者认为我国居民膳食脂质摄入情况基本合理,但由于地域差异较大,在进行膳食指导时（如关于补充ＥＰＡ,ＤＨＡ 的问题）应对不同地区的情况进行具体分析,有针对性地提出建议

Analysis on the dietary lipid pattern in different areas of China

Based on the "Total Diet Study" conducted in 1990, food samples from urban and rural inhabitants in the four regions of China(North I, North II, South I and South II) were analyzed separately. The results showed that, except the status in South II, the amount of fat and cholesterol intake existed obvious differences between urban and rural inhabitants in the same region. The dietary fat and cholesterol intake of rural inhabitants in North II region was obvious inadequate. Dietary fat intake of urban inhabitants was high and the cholesterol intake was higher than the level of 300 mg per capita. The results showed that the ratio of polyunsaturated fatty acids was relatively low but the ratio of monounsaturated fatty acids was relatively high for dietary fat in two southern regions. It might be beneficial to increase plant oil which contains high amount of polyunsaturated fatty acids for the inhabitants in southern regions. From these results, we concluded that the dietary lipids intake of Chinese inhabitants was generally appropriate. Considering the great difference in economic development and dietetic culture, the dietary suggestions should be different regions to regions.
