Cool, I'll start smoking and eating Doritos!

I'm feeling healthier already!!!

Again, JOKING.

Seriously, maybe it is tolerated... but for how long? Just because there are "no problems" for several years... 5... 10... 20... doesn't mean that it isn't causing problems! If it's a neurotoxin then I'd like to eat as little as possible.
Glutamic acid naturally occurring in foods would be okay, though - like soy sauce. In moderation. Tweet
