About us

The Food Intolerance Network consists of over 21,000 families, mostly in Australia and New Zealand but with members in USA, UK, EU, Canada and several other countries. A grateful member just summarised what we do as "helping families and taking corporations to task". We'd say that's exactly what we do.

The Network provides

  • independent information about the effects of food on behaviour, health and learning in both children and adults, and
  • support for families using a low-chemical elimination diet free of additives, low in salicylates, amines and flavour enhancers (FAILSAFE) for health, behaviour and learning problems.

The Network is run as a free service and is an unincorporated body whose costs have been met for the past 31 years from the sale of Sue Dengate's books and by giving talks. The business entity is Sue Dengate, registered for GST and Australian Business Number ABN 72 705 112 854. The mailing address is PO Box 718, Woolgoolga NSW 2456, Australia.

The Network runs an active Facebook page with over 21,000 members, sends an electronic newsletter to these families, has in the past arranged talks on demand, lobbies Ministers and food regulators and runs an active website which has seen nearly 14 million hits since 1999.
