Do a stocktake at home before planning a weekly menu and shopping list. Scan the contents of your pantry, fridge and freezer and write a list of everything. Work out what you can use to make meals and snacks and which items you need to use first (before they spoil) or freeze for later.
Note: If a food is past its best before date it can still be eaten but it may not be as tasty or high in nutrients. However food past its use by date is unsafe to eat and should be thrown away.
