Work out the water, plan actual meals and expand gradually without filling your home with food you will never use.
Three days of supplies can look reassuring until you check what is actually inside the cupboard. The water may cover only one person. The food may need an electric stove. The family member with an allergy may have nothing suitable. Before you buy more, make sure your first three days really work.
Then expand deliberately. Norway recommends a week of self-preparedness, while Germany advises aiming for ten days when possible and building up from at least three. These are useful planning benchmarks, not an instruction to make one expensive shopping trip. [1][2]
Count water before counting cans
The UK checklist specifies three litres of drinking water per person per day, with additional water needed for cooking and washing. At that drinking-only rate, one person needs nine litres for three days or 21 litres for a week. Four people need 36 litres for three days or 84 litres for seven. [3]
Those calculations are a starting allowance, not a universal ceiling. Account for household circumstances and local advice, and add water for pets and other uses. If a meal needs water to prepare, list that requirement separately instead of quietly taking it from the drinking supply.
Check the storage space before bringing containers home. Could everyone lift or pour from them? Would a leak damage medicines or electrical equipment? Smaller containers may be easier for your household to handle. Keep purchased water according to its label and use the manufacturer's storage and replacement guidance.
Build meals rather than a pile of ingredients
Write a three-day menu using shelf-stable foods your household already eats. Include breakfast, lunch, dinner and the snacks people normally need. Check labels for preparation instructions, allergens, storage after opening and serving sizes. Count actual portions instead of assuming that one package equals one meal.
Sweden's preparedness guidance emphasizes food that provides energy, stores at room temperature and needs little water or preparation, including food that can be eaten without cooking. [4] A no-cook plan avoids making the whole food supply dependent on a backup stove.
Try one complete meal before buying multiples. Open the packaging with the tools you intend to keep in the kit. Ask whether everyone can eat it, whether the portions are realistic and what cleanup requires. A manual can opener is useful only if it fits the cans and someone can operate it.
Choose package sizes that suit one sitting when refrigeration may be unavailable. Do not plan to keep opened leftovers at room temperature. For food affected by an actual outage, follow official food-safety guidance; never taste questionable food to decide whether it is safe. [5]
Add one usable day at a time
Once the first three days are complete, add a fourth day of drinking water and meals. Repeat for days five through seven as budget and space allow. Keep a running total so an extra bag of snacks does not get mistaken for a balanced extra day.
Include suitable infant food, dietary requirements and pet food in the same count. Keep medicines on a separate planning list and discuss continuity with a pharmacist or clinician rather than changing a prescription or dose yourself.
Make the reserve part of normal shopping
Write dates where you can see them and use older items in ordinary meals before replacing them. Put new purchases behind older stock. Keep a short inventory with quantities, storage locations and the next review date. A household change should trigger a review too.
The goal is a reserve you understand and maintain. Seven usable days are more valuable than an impressive shelf of food that needs missing water, equipment or ingredients. Finish the first three, then build the next four with the same care.
