Funny that I can confirm that part of this is actually true, Chinese Hot Pot is addicting due to the chemicals that are dropped inside of the "soup", one of them is MSG, an excitotoxin, which makes your brain think that the shit you are eating is amazingly delicious.

I dunno about becoming green, but a few researchers suggest that MSG overexcites the brain so much that it causes the damage or death of the cells, leading to Alzheimer's, Parkison's or other diseases.
