摘　　要：目的了解上海市常见市售食品中反式脂肪酸(TFAs)含量,评估上海15岁及以上居民膳食TFAs的摄入水平及其潜在健康风险。方法在本市超市、农贸市场、餐饮店等采样点采集11大类664份食品样品,采用《食品安全国家标准食品中反式脂肪酸的测定》(GB 5009.257—2016)检测TFAs含量。结合“2013年上海市居民膳食与健康状况监测”消费量数据,采用简单分布模型(确定性评估)方法,计算每个个体每日TFAs摄入量及其供能比。结果在各类食品中,植物油中TFAs平均含量最高,达0.7 g/100 g,乳及乳制品中TFAs平均含量次之,为0.67 g/100 g,牛羊肉及其制品中的TFAs平均含量也较高,为0.51 g/100 g。上海市15岁及以上人群TFAs平均摄入量为0.34 g/d,平均供能比为0.18%,远低于WHO的建议水平(1%)。从个体TFAs供能比在人群中的分布来看,大部分居民供能比在0.1%~0.3%范围内,最大值为0.68%。从不同类食品对TFAs摄入的贡献率来看,加工食品占总摄入水平的75.16%,其中植物油贡献率最高,约占51.58%。结论植物油是上海市15岁及以上居民膳食TFAs的最主要来源;上海市15岁及以上人群膳食摄入TFAs的健康风险很低。Objective The aim of this study was to determine the content of trans fatty acids(TFAs)in common foods sold in Shanghai and the consumption of these foods,and to assess the dietary intake of TFAs and its potential health risks among residents aged 15 years and older in Shanghai.Methods Six hundred and sixty-four food samples from 11 categories were collected from supermarkets,farmers’markets,restaurants,and other sampling sites in Shanghai.The TFA content was determined using the standard method GB 5009.257—2016.Combined with food consumption data from the“2013 Shanghai Diet and Health Survey”,the daily TFA intake and energy supply ratio of each individual were calculated using a simple distribution model(deterministic assessment).Results The average TFA content was highest in vegetable oil(0.7 g/100 g),followed by milk and dairy products(0.67 g/100 g).The average TFA contents of beef,mutton,and their products were also high(0.51 g/100 g).The average TFA intake was 0.34 g/d,and the average energy supply ratio was 0.18%,which is well below the ratio recommended by the World Health Organization(1%).The TFA energy supply ratio of most residents was in the range of 0.1%-0.3%,with a maximum value of 0.69%.Processed foods accounted for 75.16% of the total intake,with vegetable oil contributing the most at 51.58%.Conclusion Vegetable oil is the main source of dietary TFAs for residents aged 15 years and older in Shanghai.The health risks of dietary TFA intake in the population aged over 15 years in Shanghai are very low.
