Also from the study (emphasis mine):<p>&gt; The results suggest that large doses of MSG given <i>without food</i> may elicit more symptoms than a placebo in individuals who believe that they react adversely to MSG. However, the frequency of the responses was low and <i>the responses reported were inconsistent and were not reproducible</i>. The responses were <i>not observed when MSG was given with food</i>.<p>So, the study demonstrated that relatively high doses of MSG given straight to people causes a scattering of inconsistent reactions, but that MSG in food does nothing.
