I didn't realise that my two year old's frequent tantrums, inconsolable crying and inability to listen to instructions were due to food until our local supermarket ran out of Zach's favourite flavoured rice cakes. He used to eat those ricecakes every day for morning tea. When the ricecakes went off the shelf and he wasn't eating them, you'd tell him to stop and he would stop, you'd say no and he'd accept it- he wouldn't have a meltdown or a tantrum. He was also vomiting five nights out of seven and we didn't know why but when we cut out salicylates and glutamates, that stopped too. The culprits for Zach turned out to be flavour enhancers (621, 627, 631, 635) and fruit such as grapes and strawberries. - Kim, NSW
