聊聊食品中添加剂问题？Yeast extract算是不好的添加剂吗？有人说是超级味精，是吗？

"Yeast extract has replaced monosodium glutamate, or MSG, as a taste-booster in most processed foods because it appears to be a natural ingredient on food labels. However, yeast extract contains the same concentrated free glutamic acid as MSG."

我现在生抽尽量买：

Lee Kum Kee Organic Premium Soy Sauce

老抽尽量买：

Lee Kum Kee Premium Dark Soy Sauce

这两个是不放添加剂、不放味精的。超市里能找到不放添加剂、不放味精的不多的。

其实，味精是种氨基酸，叫谷氨酸钠，为人类生长发育和代谢所需。少量味精对身体、尤其肝脏有益。只有少数人对大量味精过敏

总感觉这类化学物质不利于身体健康，家里炒菜或其它自制食品已经很多年不放味精了。

在外面买食物，有味精的基本不买。

差亦。生物体都是各种化学成分构成的。谷氨酸普遍存在于各种动植物中，每天进食中所含量远远超过所用的味精量

可能我应该说是人工合成的无机化学物质？可能我的叙述不够严谨？

食用和药用的谷氨酸钠，都是从谷物中提取的。不是合成的

你说错了. 谷氨酸和MSG虽然相似,但完全不是一个东西.

Glutamate vs Monosodium Glutamate.

一个是好东西. 一个是excitoxin.

现在的美国junkfood基本都是靠MSG. 基本就是垃圾+MSG打包的垃圾.

美国人常常怪中国食物. 其实美国人自己的食物MSG用的更多.

不得不说，你买的老抽是有添加剂的

Soy sauce (water, salt, soybean, wheat flour), caramel color, sugar, potassium sorbate added as a preservative, Disodium 5-Inosinate and Disodium 5-Guanylate as flavor enhancers.

我没有足够的知识在这个问题上作出正确的判断。但你说的和很长时间人们对味精的负面共识似乎相左呀：

"In conclusion we would like to state that although MSG has proven its value as an enhancer of flavour, different studies have hinted at possible toxic effects related to this popular food-additive. These toxic effects include CNS disorder, obesity, disruptions in adipose tissue physiology, hepatic damage, CRS and reproductive malfunctions. These threats might have hitherto been underestimated. In the meantime, people keep using ever larger amounts of MSG unaware of the possible consequences. Further studies need to be undertaken in order to assess the connection between MSG and cardiovascular disorders, headache, and hypertension in human models. MSG is a controversial food-additive used in canned food, crackers, meat, salad dressings, frozen dinners and a myriad of other products. It is found in local supermarkets, restaurants and school cafeterias alike. While MSG probably has huge benefits to the food industry, the ubiquitous use of this food-additive could have negative consequences for public health. If more substantive evidence of MSG-toxicity would be provided, a total ban on the use of MSG as a flavour enhancer would not be unwise to consider."

但我确实不知对否。

只懂事实. 一个是L-Glutamic Acid 一个是D-glutamic Acid
