fatty acids (TFAs) have been proven to have an adverse effect on human health by interfering with n-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) synthesis. LC-PUFA n-3 are necessary for the development and maturation of the nervous system and retina during the prenatal period and infancy. TFAs are not synthesized de novo in the human body. Their presence in body fluids arises from the diet. The aim of our study was to determine the content of TFAs in individual meals and in a whole-day hospital diet intended for pregnant and breastfeeding women. Samples were collected from six different hospitals in Poland which voluntarily applied to the "Mum's Diet" Pilot Program. The content of fatty acids, including TFAs, was determined by gas chromatography coupled with mass spectrometry (GC-MS). The TFAs content in the whole-day hospital diets ranged from 3.86 to 8.37% of all fatty acids (% /). Food products served for elevenses and afternoon snacks contributed the highest amounts of TFAs. These mainly included dairy products containing TFAs of natural origins. The estimated average intake of TFAs with the hospital diet was 0.72 g/person/day (range: 0.34-1.16 g/person/day) and did not exceed the maximum level of 1% of dietary energy recommended by the World Health Organization.
脂肪酸（TFAs）已被证明通过干扰 n-3 长链多不饱和脂肪酸（n-3 LC-PUFA）的合成对人体健康产生不利影响。LC-PUFA n-3 对于胎儿期和婴儿期神经系统和视网膜的发育和成熟是必需的。TFAs 不能在人体内从头合成。它们在体液中的存在源于饮食。我们的研究目的是确定个体餐和为孕妇和哺乳期妇女提供的全天医院饮食中 TFAs 的含量。样本取自波兰六家自愿参加“妈妈饮食”试点计划的不同医院。通过气相色谱-质谱联用（GC-MS）测定脂肪酸（包括 TFAs）的含量。全天医院饮食中的 TFAs 含量占所有脂肪酸的 3.86%至 8.37%（%/）。上午茶点和下午小吃供应的食品产品中 TFAs 含量最高。这些产品主要包括含有天然 TFAs 的乳制品。通过医院饮食估计的 TFAs 平均摄入量为 0.72 克/人/天（范围：0.34-1.16 克/人/天），未超过世界卫生组织推荐的饮食能量 1%的最大摄入量。
