MSG Functions Like Ketamine by Flooding Brain With Glutamate to Enhance Taste

What was said

"MSG is lighting up your brain with glutamate, which is the same kind of thing that something like ketamine does. Okay, you're lighting up your brain. You're putting a surge of glutamate. And in this case, it's obviously not going to the extreme like it is with ketamine, but similar mechanism, a flood of glutamate to make your brain feel good and almost disassociate from whatever you're eating."

The speaker compares MSG's neurological effect to ketamine, stating both flood the brain with glutamate to create pleasurable sensations. He argues MSG causes the brain to 'disassociate' from food while eating, borrowing tomorrow's reward for today's meal. Despite acknowledging lack of randomized controlled trials proving harm, he cites mechanistic and rodent studies showing concerning brain activity patterns.
