Emergency food kits are marketed by "servings," but servings vary wildly in size. The number that matters is total calories, followed by how much water the food needs and how long it lasts on the shelf. This guide compares kits on those three numbers, using what each manufacturer publishes.
Picks are research-based, from manufacturer specs and published data. We do not test or taste-test products.
Start with pantry food, then add a kit
Ready.gov's advice is simple: store at least a several-day supply of non-perishable food, favoring canned foods, dry mixes and other staples that do not require refrigeration, cooking, water or special preparation. Include a manual can opener and eating utensils, and remember any special dietary needs.
Freeze-dried kits make sense on top of that pantry base when you want long shelf life and compact storage for a 2-week or longer plan. The American Red Cross recommends a 2-week supply of food for home (3 days for evacuation).
Calorie math: count calories, not servings
FDA uses 2,000 calories a day as "a general guide for nutrition advice." Individual needs vary with age, size and activity, but 2,000 per person per day is a reasonable planning number. The formula is: people × days × 2,000 calories.
- 2 adults, 2 weeks: 2 × 14 × 2,000 = 56,000 calories
- A kit listing 24 servings and about 6,000 calories covers roughly 3 person-days, not 24 meals' worth of full days
- Check calories per day on 72-hour kits: some fall below 2,000
Water is part of the food plan
Freeze-dried meals need water to rehydrate, and that water comes out of your stored supply. A bucket that needs 120 cups needs 7.5 gallons. Add food-prep water on top of CDC's 1 gallon per person per day drinking-and-sanitation baseline, or choose no-water options like ration bars for part of the plan.
Most freeze-dried meals are best with hot water. Without power you will need a safe way to heat it: an outdoor camp stove, or an electric kettle on a power station. Never use a camp stove indoors.
Reading shelf-life claims
Shelf-life claims differ in meaning. Mountain House offers a 30-year taste guarantee; ReadyWise says up to 25 years; Peak Refuel says 10 years; ration bars are often 5 years. Storage conditions matter: keep kits cool and dry, write the purchase date on the bucket, and set a reminder before the expiry date.

Frequently asked questions
- How many calories per day should an emergency food supply have?
- FDA uses 2,000 calories a day as a general guide. Plan people × days × 2,000, and adjust for children, older adults and very active people.
- Is a "72-hour kit" enough?
- It covers a short outage for one person, but check calories per day; some fall below 2,000. The Red Cross recommends a 2-week supply at home.
- Do freeze-dried meals really last 25–30 years?
- That is what Mountain House (30-year taste guarantee) and ReadyWise (up to 25 years) state. Store kits cool and dry, and treat any claim as manufacturer-stated.
- What if I can't boil water?
- Keep some no-cook food: canned goods, peanut butter, crackers or ration bars that need no water. Never use a camp stove or grill indoors.
