I recently came across your website while googling symptoms my 4 yr old daughter displayed after eating KFC chips. My partner had taken our children to town and as a treat got some KFC. When I came home from work both my kids were asleep which is a bit unusual for 6pm. My partner was in an incredibly cranky mood and said he felt like crap because of the KFC.

When my 4 yr old woke up her eyes were very red and swollen and weepy. At first I thought she had conjunctivitis and washed her eyes with a warm salty water mix. My partner then said her eyes swelled up immediately after eating the KFC. I believed straight away that she had an allergic reaction to the chips, which is all she ate. Our 1 yr old would not eat any of it. 2 weeks later we went to the movies and my 4 yr old ate a child size popcorn and had a similar but less severe reaction of red eyelids and drowsiness. I was now convinced she had developed a reaction to the salt used. Neither of these foods had labelling about what the ingredients were. Once I had read stories and information from your website it started to dawn on me how many other times she had reactions to foods. The biggest one being after eating a peanut butter sandwich some months before the KFC incident. After eating the sandwich she threw up, she had never had that reaction to peanut butter before. In fact she had never thrown up since being a baby.

I truly believe the 600 numbers have created her allergic reaction to peanuts and have since started to read all labels of the foods she eats. The doctor and nurse at my daughter's last check up did acknowledge that she could be allergic to those numbers but could offer very little advice except to cut them from our diets. On the peanut allergy they recommended not giving her peanuts for a while to let her immune system settle down. 

Since cutting out any food with those numbers and not eating fast food my daughter has not had any more reactions with swollen eyes or runny nose. - Rebecca, by email

COMMENT FROM SUE

Some experts think that food allergies are increasing, but they don't know why. The newer flavour enhancers called ribonucleotides (635, 627 and 631) are known to boost the immune system, so in theory it is possible they could lead to true allergies which are essentially an over-boosted immune system. This is not mentioned in the scientific literature but was suggested to me by an immunology graduate whose own child developed true allergies during two weeks of 635 reactions while her parents, doctors and caregivers tried to work out the cause of her rash. (It was chicken flavoured crackers with E635 given to her at the childcare centre). We have noticed that some other children and adults in our network have also developed true allergies after reactions to 635. We wonder whether these additives could contribute to an increase in allergies particularly since they are added to baby formulas. But is anyone looking? 

We would like to hear from anyone who has developed true allergies after suffering a reaction to the 600 number flavour enhancers.
