"Congratulations on an excellent website, I wish I'd found it a few months ago when I was scratching myself until I was bleeding from the worst rash I have ever had. Just in case some people think that food additives only affect children, I'm 56 and another victim of 635.

"I believe that packet soup was what triggered the rash, then things like BBQ chicken from Woolies, pizza and even KFC, although I can't prove that it contains 635 (but I bet it does) … The most amazing thing is that neither my allergist nor my dermatologist had heard of 635. I could have saved the $1000 that I spent at the specialists. My allergy specialist says I can now safely eat those foods again because the rash has gone but I won't be charging into a 635 diet to see if it comes back. Nine months of hell was long enough for me." – by email.
