【摘要】：通过走访深圳主要农贸市场和各大超市,共采集常见食物(如谷类及谷类产品、蔬菜、豆制品和肉类等)共340批次,按照GB/T 5009.6—2003"食品中脂肪的测定"第一法和微波消解-电感耦合等离子体发射光谱法,对样品中的脂肪、钠进行测定,并结合深圳居民每日膳食摄入量,对深圳居民膳食中脂肪、钠的日均摄入量进行估算。结果显示,深圳市居民脂肪摄入的主要来源为植物油和猪肉,脂肪日均摄入量为102 g,钠摄入的主要来源为食盐、酱及酱油,日均钠的摄入量为4 737 mg,均高于《中国居民膳食营养素参考摄入量》(2013版)中建议的RNI/AI值。建议深圳居民适当减少高脂肪、高钠食物的摄入,优化膳食结构,预防和控制营养相关的慢性病。
[Abstract]:By visiting major farmers' markets and supermarkets in Shenzhen, 340 batches of common foods (such as cereals and cereals, vegetables, beans and meat) were collected. According to the first method of GB / T 5009.6-2003 "determination of Fat in Food" and the microwave digestion-inductively coupled plasma emission spectrometry (ICP-AES), the fat and sodium in the sample were determined, combined with the daily dietary intake of Shenzhen residents. The daily intake of fat and sodium in the diet of Shenzhen residents was estimated. The results showed that the main sources of fat intake in Shenzhen residents were vegetable oil and pork, and the average daily fat intake was 102 g. The main sources of sodium intake were salt, sauce and soy sauce. The daily average sodium intake was 4 737 mg, which was higher than the RNI / AI value suggested in the reference intake of Dietary Nutrition for Chinese residents (2013). It is suggested that Shenzhen residents should reduce the intake of high fat and sodium foods, optimize their dietary structure, and prevent and control nutrition-related chronic diseases.
