The lipid fraction of margarines and fast food French fries, two types of foods traditionally high in fatty acids (TFA), is assessed. TFA data reported worldwide during the last 20 years have been gathered and show that some countries still report high TFA amounts in these products. The content of TFA was analysed in margarines (two store and four premium brands) and French-fries from fast-food restaurants (five chains). All samples were collected in Pamplona (Navarra, Spain). The margarines showed mean values of 0.68% and 0.43% (g TFA/100 g fat) for the store and premium brands, respectively. The French fries' values ranged from 0.49% to 0.89%. All samples were lower than the 2% set by some European countries as the maximum legal content of TFA in fats, and contained less than 0.5 g/serving, so they could also be considered " free products". This work confirmed that the presence of TFA is not significant in the two analysed products and contributes updated food composition tables, key tools for epidemiological and nutrition studies.
对人造黄油和快餐薯条这两种传统上富含反式脂肪酸（TFA）的食品的脂质部分进行了评估。收集了过去20年全球范围内报告的TFA数据，结果显示一些国家报告称这些产品中的TFA含量仍然很高。分析了人造黄油（两个普通品牌和四个优质品牌）以及快餐店薯条（五个连锁店）中的TFA含量。所有样品均在西班牙纳瓦拉省潘普洛纳采集。普通品牌人造黄油的TFA平均值分别为0.68%和0.43%（g TFA/100 g脂肪），优质品牌的分别为0.43%。薯条的TFA含量在0.49%至0.89%之间。所有样品均低于一些欧洲国家规定的脂肪中TFA的最大法定含量2%，且每份含量低于0.5 g，因此它们也可被视为“无反式脂肪酸产品”。这项研究证实，在这两种被分析的产品中，反式脂肪酸的含量并不显著，并为流行病学和营养研究的关键工具——食品成分表提供了最新数据。
