The assumptions

Each person's daily energy comes from their age band, the same figures the SupKit app uses.

Babies are planned separately: their milk and food go on the checklist as feeding supplies.

The shopping list

Calories for each item are SupKit's catalogue estimates. SupKit estimate Swap in what your household actually likes eating.

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.

• UK food law names 14 major allergens, including cereals containing gluten, milk, eggs, fish, peanuts, tree nuts, soya, sesame, celery, mustard and sulphites.²
• On pre-packed food in the UK, these allergens must be emphasised in the ingredients list, for example in bold.²
• 'May contain' warnings aren't a legal requirement, so a missing warning doesn't guarantee a food is free of an allergen.²

Young children

• The NHS advises not giving whole nuts to children under 5, because they can choke on them.³
• If allergies run in the family, the NHS suggests talking to a GP or health visitor before introducing nuts.³
• Babies shouldn't eat much salt, so salty tinned and packet foods aren't suitable for them.³
