Six people presenting Chinese Restaurant Syndrome symptoms consumed a liquid solution containing 6 grams of MSG and an MSG-free control solution for comparison in a double-blind test.
None responded only to MSG. Two of the six subjects reacted slightly to both the control solution and to the MSG solution, while the remaining four people had no reaction to either solution. The study confirmed that MSG does not cause Chinese Restaurant Syndrome in most people who claimed to suffer from the syndrome.
