Did you try the things I suggested here?<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;edit?id=10866718" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;edit?id=10866718</a><p>It would be really interesting to discover someone who was genuinely sensitive to monosodium glutamate but <i>not</i> to sodium or free glutamates in other foods. I&#x27;m not sure how that would be explainable.<p>There have been many blinded experiments looking for glutamate reactions (using MSG as the vector), and they&#x27;re not inconclusive; they appear to refute &quot;Chinese Restaurant Syndrome&quot;.
