Emergency Food Supply Guide
When a disaster strikes, store shelves empty within hours. We saw it during Hurricane Harvey in 2017, we see it with every major storm warning, and we saw it nationwide during the first weeks of the COVID-19 pandemic in 2020. Building an emergency food supply is not alarmism: it is common sense. FEMA recommends that every household maintain food self-sufficiency for at least 72 hours, and suggests extending that to 7 days if you live in an area prone to isolation.
The key is not to stockpile food randomly, but to plan a supply that meets your nutritional needs, lasts months or years without refrigeration, and consists of food you actually want to eat. A stockpile of items you would never touch is a waste of money and space.
How Many Calories Do You Need
In an emergency, your body needs energy for maintaining vital functions and for the physical activity the situation demands (cleanup, movement, staying warm). The WHO sets a reference minimum of 2,000 kcal per person per day for adults in crisis situations. This varies:
- Active adults: 2,000–2,500 kcal/day.
- Children ages 4–10: 1,200–1,800 kcal/day.
- Teenagers: 1,800–2,500 kcal/day (they are still growing).
- Sedentary elderly: 1,600–2,000 kcal/day.
- Pregnant or nursing women: add 300–500 extra kcal per day.
Our emergency planner calculates exact amounts per person based on age and scenario duration.
Essential Foods for Your Emergency Pantry
These are the food categories that offer the best balance of nutrition, shelf life, and practicality:
- Canned goods: beans, tuna, chicken, vegetables, and soups. No preparation needed.
- Grains and legumes: rice, pasta, oats, and dried beans. Long shelf life, calorie-dense.
- Freeze-dried meals: Mountain House, Augason Farms. 25+ year shelf life, just add water.
- Energy and protein bars: compact, calorie-dense, no preparation needed.
- Nuts and dried fruit: healthy fats and quick energy. Store in airtight containers.
- Powdered milk and peanut butter: protein sources that last months unopened.
Storage Tips
- Store food in a cool (50–70°F), dark place with low humidity
- Use airtight containers to protect against moisture and pests
- Apply FIFO: first in, first out. Eat the oldest items first
- Check expiration dates during your twice-yearly kit review
- Keep a manual can opener with your food supply
Frequently asked questions
What is the best emergency food bucket on the market?
The three most-purchased emergency food buckets in the US are Mountain House Just In Case (12 freeze-dried entrees, 30-year shelf life, ~$120), ReadyWise 72-Hour (32 servings of breakfasts and entrees, 25-year shelf life, ~$90), and Augason Farms 30-Day 1-Person sold at Costco (307 servings, 25-year shelf life, ~$170). Mountain House wins on taste in independent reviews; ReadyWise is best for value per serving; the Costco Augason kit is the cheapest cost-per-calorie option for long-term storage. After Hurricane Helene (2024) wiped out the Asheville food supply chain for weeks, Costco buckets sold out across the Southeast in 48 hours. Match the bucket to your household calories per day, not just servings — many "servings" in budget kits are 100–150 kcal.
How long do MREs really last?
Military Meals Ready-to-Eat (MREs) last about 5 years when stored at 70°F, but only 1 year at 100°F, per the US Army Natick Soldier Center inspection scale. Civilian MREs sold by Sopakco, AmeriQual, and MRE Star follow the same heat curve. Storage in an attic or garage in the Sun Belt cuts useful life in half. To check edibility, inspect the pouch: any swelling, dark brown chemical heater bag leaking, or off smell at opening means discard. Compared with freeze-dried, MREs are heavier (1.5 lb per meal) but need no water — useful when supplies are tight, as during Hurricane Harvey (2017) when Houston neighborhoods went days without potable water. Store in a closet at 65–75°F, rotate every 3 years.
How much food do I need for 2 weeks of emergencies?
FEMA and Ready.gov now suggest up to 2 weeks of food for households in disaster-prone regions, especially after lessons learned in Hurricane Maria, Winter Storm Uri (2021), and Hurricane Helene (2024). Budget 2,000 kcal per adult per day, 1,500 per child age 4–10, 2,200 per teen. For a family of 4 (2 adults, 2 kids) over 14 days, that is roughly 108,000 total calories. Practical mix: 28 cans of hearty soup and beans, 6 lb of pasta, 4 lb of rice, 8 jars of peanut butter, 80 energy bars, 1 Augason Farms 30-day bucket, plus comfort foods. Add a manual can opener and salt. The American Red Cross also recommends one comfort food per person per day to support morale.
How do I cook food during a power outage?
During Winter Storm Uri (2021), home cooking caused dozens of CO poisonings because Texans used charcoal grills indoors — never do that. Safe options: 1) Propane camp stove (Coleman Triton or Camp Chef Everest, $80–$130) outdoors on a porch or open garage. 2) Butane stove (Iwatani ZA-3HP, ~$50) with 8-oz canisters, also outdoor use only. 3) Rocket stove or Solo Stove Ranger for wood fuel, outdoor only. 4) Backyard charcoal grill. 5) Sterno cans or Kelly Kettle for boiling water only. Always cook outside or under an open garage door; carbon monoxide kills more people after every major US storm than the storm itself, per CDC. Stock 4 lb of propane or 6 butane canisters per week of expected use.
How do I keep food cold when the power is out?
The FDA rule is simple: a closed fridge keeps food safe for 4 hours; a full closed freezer for 48 hours; a half-full freezer for 24 hours. Keep doors closed and use a fridge/freezer thermometer — anything over 40°F for more than 2 hours must be discarded. Move milk, meat, and leftovers into a Yeti Tundra 45 or Coleman Xtreme 70 cooler with block ice from the freezer; block ice lasts 3–5 days, far longer than cubes. After Hurricane Harvey (2017), Houston grocery stores ran out of ice within hours, so prep 6–8 frozen 2-liter bottles ahead of any storm. For long outages, a Jackery 1000 or EcoFlow Delta 2 can run a mini-fridge for 18–30 hours per charge — pair with a 200W solar panel for indefinite runtime.

If you do only one thing, buy shelf-stable foods your household already eats and cover at least 72 hours. You do not need military rations to get started: canned beans, tuna, crackers, nut butter, and trail mix are practical, familiar, and easy to rotate. Our food calculator estimates calories and portions, and the EmergencyKitLab planner turns that into a complete shopping list.
