What the goal actually is
A 3-day no-cook food supply means food for every person in your household for 72 hours that needs no stove, no fire, and no power grid to prepare. It sits in one spot, it stays good for years without attention, and when you need it you can open it and eat.
The caloric target for a resting adult is roughly 1,600 to 2,000 calories per day. For someone who is physically active during a disruption, carrying loads or moving on foot, the requirement rises to 2,500 calories or more. The floor for planning is 1,700 calories per person per day. Most commercial kits come close to this; a handful fall well short and market the gap with inflated serving counts.
No-cook does not mean no-water. Freeze-dried meals require water to rehydrate, ideally hot, though they work with cold water if no heat is available. That water comes out of your emergency supply, not in addition to it. We cover the math at the end of this page.
How to read the calorie math
Every brand uses different serving sizes. A kit advertising 42 "servings" could contain 8,000 total calories or 4,000 total calories depending on how the brand defines a serving. The only reliable comparison number is total calories or calories per person per day.
Look for calories per person per day
Any kit claiming to be a "72-hour supply for 1 person" should show you total calories and a daily calories figure. If it doesn't, calculate it from the nutrition label. Target at least 1,700 per day.
Serving counts mislead
A kit with 42 servings at 190 calories each has 7,980 total calories, or 2,660 per day. A kit with 18 servings at 285 calories each has 5,130 total calories. More servings does not mean more food.
Sodium is the second number to watch
Emergency food tends to be high in sodium. High-sodium meals require more water to digest safely. This is relevant for households with blood pressure conditions and anyone on a sodium-restricted diet.
Our picks
Mountain House Just-In-Case 3-Day
The most consistently recommended 72-hour kit for households. Each kit covers one person for three days at approximately 1,706 calories per day. Meals are freeze-dried and rehydrate with hot water directly in the pouch. No pot, no cookware. Mountain House confirms the meals can also be prepared with room-temperature water with double the wait time, which makes these workable without any heat source at all.
The kit includes genuine variety: Biscuits and Gravy, Granola with Milk and Blueberries, Chicken Fried Rice, Chicken and Dumplings, and Beef Stroganoff with Noodles. No artificial flavors or colors. Made in the USA since 1969. The 30-year taste guarantee is the longest in the industry for freeze-dried food.

Augason Farms 72-Hour 4-Person Pail
The most cost-effective option for a four-person household. The 4-gallon watertight pail contains 176 servings across 7 meal varieties, enough for four adults for 72 hours at roughly 2,200 calories per person per day. That calorie figure is higher than Mountain House per kit and reflects the larger serving sizes. The pail itself is a useful storage container that seals against moisture and pests.

Five meal varieties including Maple Brown Sugar Oatmeal, Creamy Potato Soup, and Creamy Chicken-Flavored Rice. Like other Augason Farms products, meals require simmering. At under $30, this is the starting point for households on a tight budget building one kit per person at a time.

The water requirement
This is the number most households forget. Freeze-dried and dehydrated meals require water that is not your drinking water. It is preparation water, and it comes on top of the water you need for drinking and hygiene.
Quick calculation for a 4-person household
Most households store water for drinking and overlook the food-prep component. If your water storage is sized for drinking only, add the prep water before you consider your supply adequate. The water calculator on the checklist accounts for this when you enter your kit type.
Storage
Both Mountain House and Augason Farms shelf-life claims assume storage below 70 degrees Fahrenheit in a cool, dry, dark location. A finished basement or interior closet is ideal. An attached garage, an attic, or a vehicle are among the worst common storage locations. Temperatures above 90 degrees Fahrenheit roughly cut effective shelf life in half.
The Mountain House kit ships in a compact rectangular box that stacks easily. The Augason Farms 4-person pail is a sealed bucket, stackable and resealable if you open it. Neither requires climate control beyond keeping them out of extreme heat. Date each kit with a marker when you store it so you know when it was purchased.
NWS recommendation
For most households, the simplest approach: one Mountain House Just-In-Case 3-Day kit per person. Scale to your household size, store them together, and add 0.75 gallons of water per kit to your water storage calculation. The cost is higher per person than the Augason Farms options, but the no-heat preparation makes it genuinely usable in any power-outage scenario.
If budget is the primary constraint, the Augason Farms 72-Hour 1-Person kit at $20 to $30 per person is a legitimate starting point. Add a camp stove or butane burner alongside it and your food supply is complete. The Augason Farms 4-Person Pail is the best single purchase for a family of four that already has a cooking method covered.
