味精的化学名称叫谷氨酸钠。最初生产味精多是采用天然蛋白质水解制成,随着现代科学的不断发展,逐渐将天然蛋白改成粮食与糖等原料经过发酵加工而成。日常食用味精,是没有什么毒副作用的,但少数人食后也会引起头晕、头痛。尤其是孕妇及婴儿,往往较为敏感,食后会出现一系列的其他症状。怀孕、哺乳期的妇女,随着胎儿及哺乳的需要,饮食结构明显改变,一般都进食含有较高蛋白质的食品,促使体内蛋白质的含量明显高于正常阶段。由于蛋白质含有丰富的氨基酸(其中包括谷氨酸),致使体内氨基酸代谢处于超负荷运转,大量谷氨酸随着乳汁进入婴儿体内,在婴儿胃酸的化学作用下与锌结合, MSG’s chemical name is sodium glutamate. The initial production of MSG is made using natural protein hydrolysis, with the continuous development of modern science, and gradually natural protein into food and sugar and other raw materials after fermentation process. Daily consumption of MSG, there is no side effects, but a few people will cause dizziness after eating, headache. Especially pregnant women and infants, are often more sensitive, there will be a series of other symptoms after eating. Pregnant and lactating women, with the needs of the fetus and breastfeeding, diet changes significantly, generally eat foods containing higher protein, prompting the body’s protein content was significantly higher than the normal stage. As the protein is rich in amino acids (including glutamic acid), resulting in the metabolism of the body in overload operation, a large number of glutamic acid into the baby with the milk in the baby under the chemical reaction of gastric acid with zinc,
