    Welcome to the Food Intolerance Network

    Hello Everyone

    Here are some great kids paying tribute to the cover of the Failsafe Cookbook – thanks Jodie!

    The Food Intolerance Network provides support for a membership of over 20,000 families managing food after using an elimination and challenge protocol developed by Sydney's Royal Prince Alfred Hospital Allergy Unit.

    We help both children and adults with independent information about the effects of food on behaviour, health and learning. We identify and avoid harmful food additives and show you how to choose foods low in salicylates, amines and flavour enhancers, all based on the best science.

    The latest newsletter provides news, research, reader reports, recipes and highlights an overlooked cause for the causes of rising violence- read it now.
