Sharp's video is actually a response to a 2008 viral video "The Truth about MSG", in which chiropractor and nutritionist Vincent Bellonzi makes a series of scientific-sounding claims on how MSG is a toxin that "excites the reward system", makes people fat and unable to control their emotions, and much more.
夏普的视频实际上是对2008年疯传的“关于味精的真相”的一个视频的回应。在这个视频中,脊椎按摩师兼营养学家文森特·贝伦兹发表了一系列听起来符合科学规律的主张,他表示,味精是一种可以“刺激奖励系统”的毒素,使人们发胖,还使人们无法控制他们的情绪等等。
As a quick recap, here's what you need to know about MSG. Naturally occurring in many protein-rich foods is glutamic acid, a chemical widely used by living organisms to make proteins in the body.
简单概括一下你需要了解的关于味精的内容。谷氨酸原本就存在于许多富含蛋白质的食物中,它是生物体用来在体内合成蛋白质的一种被广泛应用的化学物质。
When you dissolve this acid or one of its salts in water, you end up with negative ions called glutamates, responsible for that savoury umami flavour. Classic examples of naturally glutamate-rich foods are canned tomatoes, soy sauce, and aged cheese.
当你在水中溶解这种酸或它的盐类物质的时候,你就会得到谷氨酸盐负离子,就是它使食物产生鲜味的。原本就富含谷氨酸的典型食物有罐装西红柿、酱油和陈年奶酪。
