Studies investigating "sensitivity"



Purpose:
To test the validity of Chinese Restaurant Syndrome among self-reported sufferers.
Research Institution:
Department of Physiology, George Washington University, School of Medicine and Health Services
Scientist(s):
R.A. Kenney
Results Published:
"The Chinese Restaurant Syndrome: An Anecdote Revisited," Food and Chemical Toxicology, 1985.
Study Design:
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.
Study Results:
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.
