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.
| Food | Typical allergens | Typically suitable for |
|---|---|---|
| Tinned chilli | varies by recipe | check the label |
| Tinned soup | varies by recipe | vegetarian |
| Baked beans | none of the main allergens in its main ingredient | vegan |
| Microwave rice pouch 250g | none of the main allergens in its main ingredient | vegan |
| Tinned tuna | fish | check the label |
| Crackers | cereals containing gluten | vegan |
| Peanut butter | peanuts | vegan, gluten free |
| Dried fruit and nuts | tree nuts | vegan, gluten free |
| Cereal bars | varies by recipe | vegetarian |
| Tinned fruit | none of the main allergens in its main ingredient | vegan, gluten free |
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
