A situation that requires immediate leaving your home always comes suddenly, leaving minimal time to get ready. In conditions of stress and panic, people often forget about the most important thing - the basic needs of the body. Alarm suitcase must be assembled in advance and its contents require regular rotation. Particular attention should be paid to food supplies, as access to stores or humanitarian aid distribution points may be completely blocked.
Properly formed NZ (emergency reserve) is capable of supporting human life for several days without loss of physical and cognitive functions. Errors in food selection, such as choosing perishable food or heavy containers, can be fatal during a long walk. It is necessary to clearly understand the difference between a ration for survival in an apartment and a kit for mobile travel.
In this article we will analyze the selection criteria, packaging methods and calculation of the required number of calories. The average weight of a food supply per adult for 3 days should not exceed 3-4 kg with a high energy value. This will allow you to maintain mobility and avoid exhaustion at a critical moment.
Basic principles of forming a food supply
The primary task when packing a backpack is to select products with maximum shelf life and minimum weight. The ideal option is considered sublimates and dry concentrates that take up little space and do not require complicated preparation. However, they can be unavailable or expensive, so classic canned goods remain the gold standard for most civilians.
It is important to consider not only caloric content, but also the need for water. Dry foods, such as biscuits or crackers, require large amounts of liquid to digest, which increases the load on your backpack if water supplies are limited. Therefore, the balance between dry and wet products must be carefully adjusted.
Use a vacuum sealer for bulky foods like bread or crackers - this will save up to 40% of space in your backpack.
The packaging must be sealed and resistant to mechanical damage. Glass jars are absolutely not suitable due to the risk of breaking and extra weight. Preference is given to tin cans with a key ring or soft foil packaging that does not rattle when walked.
Calorie content and daily intake calculation
In extreme conditions, the body's energy consumption increases significantly. If in a calm state an adult needs about 2000 kcal, then when walking with a load, stress and possible hypothermia, the need can reach 3000–3500 kcal. Lack of nutrition quickly leads to decreased concentration and physical weakness.
To plan your inventory, use the following table of energy values for common shelf-stable foods:
| Product | Weight (g) | Kcal | Shelf life (months) |
|---|---|---|---|
| Tourist biscuits | 500 | 2100 | 24 |
| Stew (beef) | 338 | 700 | 60 |
| Bitter chocolate | 100 | 550 | 12 |
| Nuts (walnuts) | 100 | 650 | 12 |
Based on these data, it is possible to make dietensuring survival. For example, a combination of one can of stew, a pack of biscuits and a chocolate bar will cover the basic energy requirement for a day of active movement. Do not forget about salt - under conditions of stress and sweating, the loss of electrolytes occurs faster.
The optimal daily diet should contain at least 50% fat and 35% carbohydrates to ensure long-term energy release.
List of must-have products (Top 5)
There is a list of products that should be included in NAZ (emergency reserve) of each person. These positions have been tested by time and the practice of survival in various climatic zones.
- 🥫 Canned meat: The main source of protein and fat. Choose top-grade stew (GOST), where the meat content is at least 95-97%, and not by-products.
- 🍫 Dark chocolate: The most accessible source of fast energy. It is advisable to choose tiles without additives (raisins, nuts can go rancid), packaged in foil.
- 🥜 Nuts and dried fruits: Dried apricots, raisins, peanuts or hazelnuts. They are compact, do not require cooking and contain trace elements.
- 🍪 Biscuits or crackers: Source of complex carbohydrates. Biscuits are preferable as they are less crumbly and are often already portioned.
- 🧂 Salt and sugar: Small sealed bags. Salt is necessary for water-salt balance, sugar for brain function and stress relief.
⚠️ Attention: Avoid foods that cause thirst (smoked foods, overly salted fish, hot spices) if water supplies are limited. Dehydration occurs faster than hunger.
Additionally, you can consider freeze-dried cereals in bags. They are light and nutritious, but it takes a while to prepare them. necessarily boiling water required. If you don't have the ability to start a fire or use a burner, this option becomes useless.
Packaging and protection from external factors
Even the best quality products can go bad if they are packaged incorrectly. Humidity, dust and rodents are the main enemies of the food supply. Each product must be isolated from the external environment.
Use heavy-duty plastic bags with zip closures. After placing canned food or dry food inside, it is better to remove the air from the bag. This will prevent oxidation and protect against odors that could attract wildlife or insects.
For tin cans, it is recommended to use fabric bags or wrap them in soft cloth. This will not only protect against corrosion, but will also reduce the noise of cans clanking against each other when walking, which can be critical in certain situations.
How to check the tightness of a jar?
Place the closed jar in warm water and press lightly. If there are air bubbles, the jar is not sealed and the product inside may be spoiled. Bloated lids (“bombage”) are a sign of bacterial infection; you should absolutely not eat this.
Water: priority number one
A person can live without food for several weeks, but without water - only a few days. When planning an evacuation, the issue of water supply is given paramount importance. Carrying water is hard (1 liter = 1 kg), but there is often no alternative.
The minimum norm for survival in a temperate climate is 2-3 liters per day. If there is a transition to heat or high altitudes, the norm increases. Your backpack should always have at least one full 1.5 liter bottle and an empty container for collecting water from natural sources.
Never drink raw water from open reservoirs without prior treatment. The risk of intestinal infections in the absence of medicine is deadly. Use disinfection tablets or portable filter straws.
☑️ Checking water supply
What NOT to take: list of prohibited products
Forming the right reserve is half the battle. The second half of success is eliminating unnecessary things from the list. Some products that are familiar in everyday life become ballast or a threat during evacuation.
- 🥛 Perishable products: Dairy products, boiled sausage, fresh bread. They will spoil in 1-2 days even in cool weather.
- 🥒 Products in glass containers: Heavy and fragile. Shards of glass in a backpack with food are a disaster.
- 🥤 Carbonated drinks: They create a feeling of false saturation, require a lot of space and can explode from changes in pressure or temperature.
- 🍬 Sticky sweets: Toffee, soft caramel. They get your hands dirty, attract insects, and can freeze to stone in the cold.
⚠️ Attention: Do not take exotic or unusual foods for your stomach. Stress and changes in diet can cause digestive upset, which in the field is tantamount to dehydration.
You should also avoid foods that require long-term cooking (whole grains, dry legumes). In conditions where you need to save fuel and time, five-minute porridge or simply steamed flakes will be much more practical.
Stock rotation and timing check
Once collected alarm case You can’t just put it in the closet and forget about it. Products tend to deteriorate and packaging tends to break down. Regular inspection is a mandatory procedure.
It is recommended to conduct an audit every six months. Time this to coincide with seasonal clock changes or the start of the holiday season. Check the integrity of the cans, the absence of rust and swelling. Inspect dry foods for moisture or mold inside the package.
There is a rotation rule: “First in, first out.” If the expiration date is approaching, use this product at home (eat canned food at dinner), and in its place put a fresh can with a later production date in your backpack. This allows you to always have an up-to-date stock without overpayments and waste.
Label each jar and package with an expiration date using a large marker. This will save time when quickly checking the contents of your backpack in the dark.
Can products be used after the expiration date?
In an emergency situation, when it comes to life and death, products that have expired (1-3 months) often remain suitable if the seal of the packaging is not broken and there are no signs of spoilage (bloating, odor, mold). Canned food and dry biscuits retain their properties the longest. However, it is not worth risking your health if you have a choice.
Do I need to take a bottle opener if there are keys on the cans?
Yes, definitely. Keys on cans often come off, become bent, or are made of too thin metal. Reliable knife or a multi-tool with a can opener should be in a separate, easily accessible pocket of the backpack, and not buried at the bottom.
How to protect food from frost in winter?
At low temperatures, fats in canned food can congeal and water in food can freeze, making food difficult to access. Keep food supplies in an inner clothing pocket close to your body or in a thermal bag. Frozen stew can be thawed by placing the jar under your clothes on your stomach.
