What to Stock by Calories, No Fridge Needed
A simple way to work out how much shelf-stable food your household needs, using calories on the label and a daily target.
Counting cans does not tell you how long your food will last. Counting calories does.
Step 1: pick a daily number
FDA uses 2,000 calories a day as a general guide, and notes that needs vary with age, sex, height, weight and activity. Health Canada publishes equations for estimating an individual’s energy needs. Use 2,000 for a typical adult. Children and smaller or less active adults usually need less. Someone doing hard physical work usually needs more.
| Household | 3 days | 7 days | 14 days | 30 days |
|---|---|---|---|---|
| 1 adult | 6,000 | 14,000 | 28,000 | 60,000 |
| 2 adults | 12,000 | 28,000 | 56,000 | 120,000 |
| 4 adults | 24,000 | 56,000 | 112,000 | 240,000 |
Step 2: add up your shelf
On each package, multiply calories per serving by servings per container.
Example only, so check your own labels: a jar labelled 190 calories per serving with 14 servings holds 2,660 calories. Five jars like that would be 13,300 calories.
Write the total on a sheet of paper taped inside the pantry door.
Step 3: balance it
Calories alone are not a diet. Ready.gov suggests:
- Ready-to-eat canned meats, fruits and vegetables
- Protein or fruit bars
- Dry cereal or granola
- Peanut butter
- Dried fruit
- Canned juice
- Non-perishable pasteurized milk
- Comfort foods
Choose foods your household already eats, and plan for allergies, diabetes, baby food and any special diet.
What lasts without a fridge
USDA FSIS gives these storage times for food kept cool and dry:
- Low-acid canned goods (meat, poultry, stews, beans, corn, peas): 2 to 5 years
- High-acid canned goods (tomatoes, most fruits, juice, pickles): 12 to 18 months
For keeping it fresh, see pantry rotation. Once a can is open without refrigeration, finish it within 2 hours, or 1 hour if it is hotter than 90°F (32°C).
