For those asking how to work out if you or your child is affected by preservatives and additives, the best way is to do an elimination and challenge diet- cut them all out for a few weeks, then trial them one at a time for a few days to see if you have any reaction. You can try it the opposite way- cut out one at a time to see if you or your children feel/ behave any "better", but I think this is more confusing because you're never quite sure what you're reacting to.

The RPA Hospital has a great elimination/challenge diet that I am working myself up to try, to see if my chronic health issues are diet related.

Note that while artificial preservatives/ additives are undoubtedly bad, there are natural components of many foods that are similar in nature to the additives and which sensitive people can react to as well. The RPA diet actually eliminates those as well so you can really get a good picture of what, if anything, you react to. The book "Fed Up" by Sue Dengate is a great resource, or check out her website for more info.

Its so scary what they put in our food!!!
