NRG-5 vs Trek'n Eat: 72-Hour Emergency Food Compared

NRG-5 vs Trek’n Eat is the question anyone asks once they start filling out the food section of their EmergencyKitLab UK kit. Both are respected references on the European market, both are marketed for 72-hour and longer emergency scenarios, and both have long shelf lives. But behind the shared “emergency food” label sit completely different philosophies. At EmergencyKitLab UK we tested both during the spring 72-hour bag drill the team runs each year, and the conclusion surprised us.

This comparison between NRG-5 and Trek’n Eat looks at calories, weight, water needed, real-world taste and cost per day. At the end you get a clear recommendation by scenario: an evacuation bag, a household kit, a long-term reserve or proper outdoor use.

Specs come from each Amazon.co.uk listing; where the listing does not publish a figure, the table says so. Trek’n Eat’s Chilli con Carne, which we used to compare here, is no longer in stock on Amazon.co.uk, so the table uses the Chicken in Curried Rice pouch from the same range.

Spec	NRG-5 Emergency Food (500 g ration)	Trek’n Eat Chicken in Curried Rice

The number that jumped out when we built the table: one 500 g NRG-5 ration costs less than a single Trek’n Eat pouch and weighs two and a half times as much in ready-to-eat food. And it needs no water. For a 72-hour emergency where water can be the scarcest resource, that single fact changes the calculation entirely.

NRG-5 Pack of 24 in detail

NRG-5 is a compressed biscuit ration built for emergency stores rather than for the camping shelf. The 24-pack sold on Amazon.co.uk holds 24 rations of 500 g in a durable, water-resistant box, with added vitamins and minerals and a minimum shelf life of ten years. The texture is similar to a dense ship’s biscuit and the flavour is neutral.

What the team likes:

• A full 500 g of ready-to-eat food per ration, for about £8.75
• Zero water required to eat it, critical when mains water is off
• At least 10 years of shelf life (perfect for a reserve you forget about)
• A pack of 24 gives you 24 rations, enough to put several days of food aside for a family of four
• The box itself is water-resistant, so it can live in a garage or under the stairs

Where it falls short:

• Monotonous taste; three days of pure NRG-5 is psychologically tough (the team confirmed it on the March drill)
• Dry texture means you drink water while chewing (no more than you would normally, but it is not “fresh” food)
• No animal protein, so for sustained use over a month you need to combine with other sources
• No warmth on consumption; in cold weather you miss a hot meal more than usual
• £210 up front is a lot for a single purchase, even if the price per ration is low

Best for: a long-term household backup, a 72-hour bag where you do not want to depend on stove plus water plus time, an urban evacuation bag where you cannot light a fire.

Trek’n Eat Chicken in Curried Rice in detail

Trek’n Eat is a European freeze-dried outdoor food brand from the Katadyn group (the water filter people). Freeze-drying removes most of the water from cooked meals such as stews, curries and pasta dishes, so the pouch is light on the shelf. Add boiling water, wait a few minutes, and the food reconstitutes into something close to the original dish.

What the team likes:

• Menu variety: the range covers curries, pasta and stews, which avoids the day-two-and-three taste fatigue
• Real meat in many recipes, useful for sustained use
• A hot meal at the end of a tough day has real moral value under stress
• One pouch costs about the same as one NRG-5 ration, so it is easy to add a few as treats

Where it falls short:

• Needs boiling water for every pouch, so stove, water and fuel are non-negotiable
• Per 100 g on the shelf it costs around two and a half times as much as NRG-5, before you add the water
• The UK listing does not state a shelf life or the calories per pouch; read the label and rotate stock
• 4.1 stars from around 130 ratings on Amazon UK, a smaller user base

Best for: an outdoor multi-day backpacking bag (low weight, real food), a household kit with active rotation where the family eats the pouches as a weekend meal every couple of years, or an emergency where you can boil water without restrictions.

Which one for your situation

The honest answer is almost never “just one”. But if you have to decide:

You are building a 72-hour bag on a tight budget: NRG-5. For about £26 you cover three days of rations (1.5 kg) without depending on a stove or extra water. Six Trek’n Eat pouches, two a day, cost around £57 and still need water and fuel. The £30 difference can go into a water filter or a torch.

You take the bag hill-walking on weekends and want a dual-purpose kit (real use + emergency): Trek’n Eat. Recipes are acceptable as bivvy dinners, you will rotate the stock annually, and you do not need a ten-year shelf life because you consume and replace.

You are building a household reserve for long scenarios (extended power cut, supply disruption): combination. NRG-5 as the unalterable nutritional anchor + Trek’n Eat for psychological variation + supermarket tinned food + rice and pulses. We cover this in the 72-hour family emergency kit guide.

You live in an area with frequent water or gas disruption (rural Scotland, parts of Wales after floods): NRG-5. The “zero water to consume” factor is not theoretical: in some council water cuts the supply is on but not potable, and bottled gas takes 48 hours to restore.

You have children or older relatives who reject unusual textures: neither is ideal, but Trek’n Eat with familiar recipes (pasta bolognese, chicken rice) has better acceptance than the neutral flavour of NRG-5. Acceptance matters: food that does not get eaten is not a reserve, it is dead weight on the shelf.

The EmergencyKitLab UK team verdict

For a first purchase aimed at real emergencies, EmergencyKitLab UK recommends NRG-5. The combination of price per ration, a ten-year minimum shelf life and independence from water and heat makes it the most reliable nutritional anchor for supply disruption scenarios. It is the product the team would put in a bag if forced to pick only one.

Trek’n Eat has its place but not as a sole option. It is complementary: it adds variety, morale and real animal protein when conditions (water + heat) allow. The team rejected basing a 72-hour reserve solely on freeze-dried meals because the dependence on stove + water + time creates a single point of failure.

An honest observation after the March 72-hour bag drill: NRG-5 fatigue hits on day three. Eating the same neutral biscuit for breakfast that you ate for dinner four times running, your body chews through it but your head resists. The strategy that worked best: two days of NRG-5 as the base + one or two Trek’n Eat pouches per day as a hot “reward” at the end. Not the cheapest, but the most realistic for sustaining morale in a prolonged scenario. Cost for one person for a week: around £55 to £65, weight 2.5 kg, all in formats compatible with a standard bag.

Key concepts for designing your food reserve

Before spending £200 on emergency rations, read 72-hour emergency kit for families, which explains which everyday supermarket products do half the job at a third of the cost, and our wider emergency food supply guide for how to size the reserve by household and days of autonomy.

To understand why freeze-dried food is not the universal solution some retailers claim, the lessons from a 5-day blackout article has the real numbers on cost, weight and palatability when the stove ran out of gas on day three.

How many calories does your family need by size and days of autonomy? The EmergencyKitLab UK planner calculates the exact reserve and splits weight across survival rations, freeze-dried meals and local tinned food.
