So in other words, glutamate is very
总而言之 在我们的日常饮食中
abundant and a very common part of our diet. Funny
谷氨酸盐是非常丰富且普遍存在的

有趣的是 味精就是一种钠盐形式的谷氨酸
So basically the mono sodium part just

if your body makes this compound and
如果你的身体自身就在产这个物质
it’s so common, then how come everyone

thinks this stuff is bad for you?
为什么你会认为它有害呢?
It all started in a letter to The New

written by a scientist to describe
给新英格兰医学院写了一封信
the unpleasant after effects
