味精的主要成分是谷氨酸钠,在肝脏中的谷氨酸丙酮酸转氨酶的代谢作用下,转化生成人体特别需要的氨基酸,它对成年人来说是没有什么危害的。但对12周以内的婴儿不利。如果乳母在摄入高蛋白饮食的同时,又食用过多的味精,谷氨酸钠就会通过乳汁进入婴儿体内,与婴儿血液中的锌发生特异性结合,生成不能被机体吸收利用的谷氨酸而随尿液排出体外,从而导致婴儿缺锌,使其出现味觉差、厌食等症状;还会造成智力减退、生长发育
The main component of MSG is sodium glutamate, which is metabolized by the glutamate pyruvate transaminase in the liver to produce amino acids that are particularly needed by the human body. It is harmless to adults. But not for infants within 12 weeks. If the lactating maternal intake of high-protein diet at the same time, eat too much MSG, monosodium glutamate will enter the baby through the milk, with the baby’s blood in the zinc binding occurs specifically to generate the body can not absorb the use of ammonia Acid and excreted with the urine, resulting in zinc deficiency in infants, making it appear bad taste, anorexia and other symptoms; will result in mental retardation, growth and development
