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.
- UK food law names 14 major allergens, including cereals containing gluten, milk, eggs, fish, peanuts, tree nuts, soya, sesame, celery, mustard and sulphites.7
- On pre-packed food in the UK, these allergens must be emphasised in the ingredients list, for example in bold.7
- 'May contain' warnings aren't a legal requirement, so a missing warning doesn't guarantee a food is free of an allergen.7
