Antidote

Another rumor about MSG is that one could treat (or prevent) the Chinese restaurant syndrome by drinking Coca-Cola.

On the face of it, that's entirely reasonable. Coke contains caffeine, which would effectively combat the headache induced by MSG; the sheer amount of water obviously relieves the thirst sensation. In fact, a cup of light coffee should do the same.

But, you know what, if you search MSG and Coca-Cola together in Google, the most widely advocated effect is, the combination becomes an aphrodisiac.

Of course that's not true. Neither MSG nor Coke has that effect, and the two certainly do not have a chemical reaction when mixed together. (Otherwise Pfizer could not have make so much money from Viagra.) But, the plot is ingenious - once again, what could make a better advertisement and induce people having that sweet brown beverage when they go to a Chinese restaurant?

Maybe that's the rare occasion when an antidote is the same as an aphrodisiac.
