Several studies have also reported correlations between brain glutamate levels and overall level of social and occupational functioning (Table 1). In genetically high risk subjects, lower levels of Glx/Cr in the mPFC were associated with lower levels of overall functioning (59). A longitudinal study at 4 T showed that loss of glutamate and glutamine in the thalamus, but not the ACC, over 7 years since first presentation correlated with impaired social functioning (34).
And while their names sound similar, and they both come from the same family of amino acids known as the glutamates, they are different. Glutamic acid is best known as a component of monosodium glutamate, while L-glutamine may be known as a supplement used by athletes to help improve immune health and recovery.

东亚国家普遍使用味精，这可能是东亚人智商高的一个一个原因。
谷氨酸钠（MSG）作为一种调味品已经使用了一个多世纪，它所提供的鲜味已被确认为第五种基本口味（仅次于甜味、咸味、酸味和苦味），对人的味觉和食欲有潜在的影响。随着年龄的增长，人们对鲜味的敏感性降低，与味觉紊乱相关疾病的发病率增加。这可能是由于老年人血清中的锌含量低于年轻人群。味精通过口腔或胃受体向大脑传递味觉信号，从而增加腮腺和胃液的唾液分泌，进而促进消化。
因此，摄入味精可以增加锌从肠道的吸收，增强食物的味道。此外，来自舌头上谷氨酸受体的输入可在初级味觉皮层中得到处理；有报道称，功能性磁共振成像显示，鲜味刺激激活了味觉皮层区域的活性。因此，研究人员推测，摄入味精可能会激活肠-脑轴。
日本鸟取大学健康科学学院医学系的Minoru Kouzuki等人发现，味精不仅仅可以满足人们的味蕾，中餐外卖食品（如鸡丝炒面、菠萝咕咾肉和糖醋排骨等菜肴）中普遍使用的味精可以帮助病人治疗痴呆症。

Glutamate levels predicted task performance in patients, such that lower glutamate levels were related to impaired cognitive control functioning.

有没感觉不如以前聪明了？
作为维生素卖，标注提高不免疫力
价格贵8倍
普通调味味精，1刀4盎司
地沟油应该确实不会损害智商
根据第四版美国精神病学会第五版的《精神疾病诊断与统计手册》的研究表明：美国人年度发病率为26%，终身发病率46%。大概是世界最高。
你见过标注glutamate的酱料吗？
中国标注含谷氨酸钠的食物非常多。
价格比食盐贵几十倍，比味精贵两倍。

国内人吃抗生素跟味精一样多，肠道BT菌早都死绝了，赖不到味精头上。
很多年不吃了
本楼，到目前为止，最佳回复。
有吗? 我怎么记得是没有什么不好，除了它本身是钠，咸味却比食盐低很多很多，所以一不小心放多了，容易摄入过量的钠。除此之外没有什么。就当盐来吃不就得了。
谷氨酸是氨基酸，吃多了应该也没啥。
中国人不吃味精几乎不可能因为酱油里含有大量味精=谷氨酸钠
美国食物总体来说就是难吃没味道，导致我整体感官敏锐度下降
只要没断酱油，恭喜你，你还在不断吃大量味精，患老年痴呆和精神病的可能性比美国人大大降低。
顺便看了一眼酱油的历史：
早在周代,贵为天子的饮食,少不了酱油。《周礼·天官·膳夫》有载,天子的饮食分为饭、饮、膳、馐、珍、酱六大类。那时酱油,是动物肉剁成肉泥再发酵生成的油,和现在鱼露的制作方法类似,被称为“醢”(hǎi三声)；还有一个在造酱时加入动物血液的重口味版本,叫做“醓”(tǎn),它们共同构成诗经《大雅-行苇》篇中的“醓醢以荐”,也就是《礼记-内则》记录的周天子饮食中的八珍之二,“淳熬”和“淳毋”,看上去好像很高大上,但其实就是肉酱油盖浇米饭。
几千年前就能在天子饮食中占有重要一席,酱油在中华民族烹饪文化中的地位可见一斑,此后,先人们又尝试在肉类之外,用黄豆、小麦发酵制酱,这一工艺经过汉唐数代人的发展,终于在南宋臻于完善,在《山家清供》一书中首次以“酱油”之名进入中华文明的记忆,而代表菜,则是用芝麻油和酱油炒春笋,颇有现在油焖笋的意思。
当然,好客又好吃的中国人不会不让他人专美。唐朝时,东渡日本的鉴真和尚带去了酱油酿造方法,从此日本人不蘸酱油就不吃鱼生。随后,酱油制作之法又相继传入朝鲜、越南、泰国、马来西亚、菲律宾、印度、孟加拉等国。
谢谢

不是，但到了体内就变成它了，味道不一样但是生理作用差别不大。
调料里有卖， accent之类的。
