By the SupKit teamUpdated

The short answer

SupKit plans on 2,250 calories a day for an adult, 1,600 calories for a child and 1,100 calories for a toddler.1 Two adults and two children need about 23,100 calories for 3 days.

The assumptions

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

WhoA day
Toddler1,100 calories
Child1,600 calories
Teenager2,400 calories
Adult2,250 calories
Older adult2,000 calories

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.

  • Canada names 11 priority allergens: eggs, milk, mustard, peanuts, crustaceans and molluscs, fish, sesame, soy, sulphites, tree nuts, and wheat and triticale.2
  • Packaged foods must declare priority allergens and gluten sources by plain source names in the ingredient list, a 'Contains' statement, or both.3
  • Companies may add a 'May contain' warning for possible cross-contamination; it is not a substitute for good manufacturing practices.3

Young children

  • Health Canada says peanuts and other nuts, seeds, popcorn and hard candies are not safe for children under four.4
  • Never give any kind of honey to babies under one, including in food, water, formula or on a soother.5
  • Prepare food for young children with little or no added salt or sugar.4
