Ahh nice straw man argument.
Nothing wrong with naturally occurring glutamate.
But see that is not what we are talking about.
MSG is added to processed foods in levels far above that which occurs naturally say like in a tomato.
The reason is it enhances the flavor of processed foods. BUT like anything one eats or ingests way too much of something is far more harmful than not eating it at all.
When researchers want fat mice they get ones that have been fed high levels of MSG.
Its not rocket science Sparky...
Anyone with an IQ above 70 can figure out that food you grow in your garden is better for you health-wise than the slop that is brewed in some factory that has all manner of crap added to it so it won't spoil or taste bad when it gets to the consumer.
You never bothered to learn much about biology and chemistry, did you? That being a fact, why are you here talking about biology and chemistry when you know absolutely nothing about it? Why is it the people who know the least about something are always the first to pretend like they do?
How is the chemical composition of added glutamate different from naturally occurring glutamate?
Since you ingest 10 times more glutamate from naturally occurring sources than you do from added sources, why are you afraid of it? Your fear makes absolutely no sense if you understand the subject, but you don't so you fear what you don't understand.
Scientists don't feed rodents MSG to make them fat.....unless they happen to be looking for grant money from scientific illiterates. Hmmm, are you in the business of allocating grant money?
