自从发现哺喂各类配方食品的早产儿比喂集合人奶的婴儿尿及血浆中牛磺酸的含量低以来,β-氨基酸在人类营养中的重要性受到重视。人们最感兴趣的是包括以牛奶和大豆蛋白为基础的婴儿配方食品中,加入与人奶中浓度大至相同的牛磺酸后结果怎样。喂予增补(强化)了牛磺酸(强化量为30μM/100ml)配方的婴儿,血浆和尿中的牛磺酸浓度与人奶喂养婴儿基本相同。此外,还使婴儿生后5周内,牛磺酸结合含胆酸与甘氨酸结合胆酸的比例(G/T)增高,然而,并未改变或增进脂肪吸收,也未改变胆酸动力学和影响婴儿的生长。本文将讨论牛磺酸是否有利于人类营养的问题。
The importance of beta-amino acids in human nutrition has been valued since it has been found that the content of taurine in preterm infants fed various types of formula is lower than in urine collected from human milk and fed in human milk. What is of most interest is the result of adding, to milk formula and soy protein-based infant formulas, the same concentrations of taurine as in human milk. Infants fed supplementation (fortification) with taurine (fortified amount of 30 μM / 100 ml) had approximately the same concentrations of taurine in plasma and urine as those fed to human milk fed infants. In addition, the ratio of taurine-bound cholic acid to glycine-bound cholic acid (G / T) was also increased within 5 weeks of birth, however, fat absorption was unchanged or improved, and cholic acid kinetics and Affect the baby’s growth. This article will discuss whether taurine is beneficial to human nutrition.
