Allergies, dietary needs and children

Plan around everyone at home: allergies, intolerances and diets come first, and familiar food matters most for children. Recipes vary between brands, so always read the label of the product you buy.

Typical allergens and diets are SupKit's guide to the main ingredient, not a product's label.

  • Under the joint Australia New Zealand code, labels must declare wheat, fish, shellfish, egg, milk, lupin, peanut, soy, sesame, named tree nuts, gluten cereals and added sulphites.3
  • Allergens must be in bold in the ingredient list, plus a separate bold summary starting with 'Contains' near the ingredients.3
  • 'May contain' statements are voluntary and not regulated by the Food Standards Code.3
