Selenium (Se) is largely associated with the protein component of foods. The processing of elemental feeds and artificial formulations used in clinical dietetic practice can, therefore, result in significant losses of Se from these products and the Se status of patients consuming these feeds may be compromised. A selection of commercial formulas typically used for enteral feeding, and for patients with cystic fibrosis, phenylketonuria and maple syrup urine disease were analysed for Se micro-fluorimetrically. Low Se contents were found in all food supplements except for Peptisorbon (0.09 mg Se/2000 kcal) and Clinifeed Protein Rich (0.08 mg Se/2000 kcal) which contained adequate daily Se levels according to the American RDI. The results show that a number of feeds are low in Se, especially those used for patients with cystic fibrosis and maple syrup urine disease. An investigation of the Se status of patients on these formulations may indicate the need for Se supplementation.
硒（Se）在很大程度上与食物的蛋白质成分相关。因此，临床饮食实践中使用的元素饲料和人工配方的加工过程可能会导致这些产品中的硒大量流失，食用这些饲料的患者的硒状况可能会受到影响。采用微量荧光法对一系列通常用于肠内喂养以及患有囊性纤维化、苯丙酮尿症和枫糖尿症患者的商业配方进行了硒含量分析。除了Peptisorbon（0.09毫克硒/2000千卡）和富含蛋白质的Clinifeed（0.08毫克硒/2000千卡），根据美国推荐膳食摄入量，这两种产品含有足够的每日硒含量外，所有食品补充剂中的硒含量都很低。结果表明，许多饲料的硒含量较低，尤其是用于囊性纤维化和枫糖尿症患者的饲料。对使用这些配方的患者的硒状况进行调查可能表明需要补充硒。
