应用总膳食研究方法对成都市城乡代表人群的膳食组成和16种营养素（碳水化合物、蛋白质、脂肪、视黄醇、硫胺素、核黄素、抗坏血酸、钙、铁、锌、镁、钾、钠、铜、锰、钻）进行了研究。结果表明：城市居民动物性食物消费普遍高于农村，其中，以猪肉为代表的肉类消费仍分别占城乡居民动物性食物消费总量的61．9％和87．6％；城乡代表性膳食组成仍以粮谷类和蔬菜等植物性为主；全市平均及城市多数食物消费水平已超过或接近推荐的2000年膳食目标，但农村与目标差距较大。全市平均及分城乡摄入的热量分别达到RDA的106．9％、102．1％和111．8％；蛋白质分别达到RDA的96．7％、104．7％和91，2％；铁、铜、锰、钴、钠的摄入量较充足，已分别达到我国RDA和WHO提出的ESADDI；但也存在全市平均及分城乡视黄醇当量、硫胺素、核黄素、抗坏血酸、钙、锌、钾均摄入不足以及城市脂肪摄入过高，农村蛋白质质量较差等值得重视的问题。与以往的研究结果比，居民的营养改善不明显。
The total dietary research method was applied to analyze the diet composition and the effects of 16 nutrients (carbohydrate, protein, fat, retinol, thiamine, riboflavin, ascorbate, calcium, iron, zinc, magnesium, Sodium, copper, manganese, diamond) were studied. The results showed that the consumption of animal food by urban residents was generally higher than that of rural areas, of which the consumption of meat represented by pork still accounted for 61.9% and 87.6% of the total consumption of animal food by urban and rural residents respectively. Composition is still dominated by cereals such as cereals and vegetables; the city average and most urban food consumption levels have exceeded or approached the recommended dietary targets in 2000, but the gap between rural areas and the larger target. The city’s average and sub-urban and rural areas respectively reached 106.9%, 102.1% and 111.8% of the RDA respectively; the proteins reached 96.7%, 104.7% and 91.2% of RDA respectively; The intakes of copper, manganese, cobalt and sodium are more abundant, and have reached the ESADDI proposed by China’s RDA and WHO separately. However, there are also the average and sub-urban retinal equivalents, thiamine, riboflavin, ascorbate, calcium, Inadequate intake of zinc and potassium and urban fat intake is too high, poor quality of rural protein, etc. worthy of attention. Compared with the results of previous studies, residents’ nutritional improvement is not obvious.
