Review: Mainstay Emergency Food Rations

I've been feeling really remiss as a prepper without a stock of MRE's and other per-packaged survival food. Like a cowboy without a Stetson, or a fisherman without a line. Military style MRE's are not easy to come by in Australia, but I was lucky enough to spot some silvery packets of goodness in the display window whilst visiting Global Gear (who have supplied me with some fun kit in the past).

I did some research online and it seemed that these were the real deal. These are the Mainstay Emergency Food Rations. These high density food bars come in three varieties, in 1200, 2400 or 3600 Calorie packs. Each of the three varieties consist of a vacuum sealed foil sachet, with extensive nutritional information, and contains a block of very solid food.

The 1200 weighs 228g (1/2lbs)and breaks into three measured blocks.

I grabbed a sample in the "Energy Bar/1200" size from Global Gear and opened it up to see what I got.

It's always a good idea to test out something like this, before you commit to perhaps a box full of something awful, but I was pleased to find that the Mainstay bars were quite palatable. A solid, slightly brittle block that for all the world felt and tasted like a coarse, buttery shortbread, with a light lemon flavour and scent. I ate a block of it, and whilst not filling, was certainly a hunger stopper.

Quite palatable, if crumbly, I can see these being a fast and easy way to keep your energy up in a challenging situation, especially if water was available. I was distinctly aware of the gritty texture, much like a very sweet, hard cornbread.

 I found that I left the uneaten portion in its wrapper and came back to it a couple of weeks later, to no noticeable effect. Properly sealed, they are designed to have a 5 year shelf life, but I expect they would still be edible long after this.
 
This ration is marketed as a "complete food" meaning that no other food intake is needed to meet all nutritional requirements in a survival situation.  Having a look at both the ingredients, and the "percent daily values" listing, it is possible to determine that these bars are indeed jam-packed with nutrition, and trace elements. Certainly not something you'd want to LIVE off, but life FROM, for sure.

Based on USCG and SOLAS standards, two blocks suffice to sustain life in "maritime settings" whilst three (a full packet) are recommended for land survival. Given the insights I made in looking at survival nutrition, and the availability of the 2400 calorie Mainstay ration in bulk from SurvivalStorehouse.com, I opted to buy a number of these from , as "get out of trouble" supplies.

I plan to stash some in my car, in my bug-out-bag, for when we go hiking or camping,  and at work, for those times when I just can't get out because of marauding hordes ...

Home Front: survival nutrition

 Its always interesting to see how food and nutrition is handled in disaster situations in film and TV. From The Walking Dead's baby formula and prison storerooms  to The Day After Tomorrow's vending machines, not to mention ZombieLand's Twinkies and Bill the (delicious) Donkey in The Postman.

I did a little reading about the "average adult daily energy intake" which lead to some interesting findings.

It is common to see "8,700kJ" as the average recommended intake, usually quoted on fast food menu's and the like, (as seen here on this poster for some tasty poultry products seasoned with 11 secret herbs and spices, as devised by a well known Kentucky Colonel.)

This figure is based in part by the Food Standard Code as published by the Australia New Zealand Standards Code (FSC). The FSC lists that value for daily intake levels based on an average adult diet. It is interesting to note however, that this doesn't take into account activity levels, and lifestyle.

It is it seems, more of a "minimum level" for and it has been suggested that it is more suited to bed-ridden individuals, rather than active survivalists, running, ducking, dodging and weaving their way through the ruins of civilization.

Interestingly when I looked up the nutritional content of current MRE kits, they suggested that servicemembers (who were classified as highly active men between the ages of 18 and 30) typically use about 4,200 Calories a day. The conversion is  1 kJ = 0.2 Calories (Cals)or 1 Calorie = 4.2 kJ, giving a figure of 17,640 kJ a little over double the "average adult intake diet".

Lets assume that post-disaster, you will not be having a sedentary desk-job life, and will be a rugged, fighting, and self-reliant survivor, chopping wood for fire, hunting and foraging (or farming) for food, and perhaps battling off marauders, zombies, triffids or the elements.

According to the FSC, and "MyDailyIntake.net", a "balanced diet for an average adult" is made up of the following nutrients each day:

Nutrient	Quantity Per Day
Energy	8,700 kilojoules
Protein	50 grams
Fat	70 grams
Carbohydrates	310 grams
Sugars	90 grams
Sodium (salt)	2.3 grams
Dietary Fibre	30 grams
Saturated Fatty Acids	24 grams

To meet up with our projects "serviceman" levels, you basically have to double that. Obviously, people have done with much less, for millennia and still managed to fight, survive and prosper, till you now find humanity all over the world. 

These "USCG/ SOLAS standard exceeding" food-bars state on their wrapper that  A daily maritime diet (being stuck on a life-boat, i presume) equals 3,333kJ, and a similar land based situation (say, stranded on a desert island) equates to 5,000kJ. However this is a base-survival diet, and wouldn't be much fun, or enough on its own to keep you fighting-fit.

Again, looking around at the figures, I found the Australian National Health and Medical Research Council published this table.

The average amount of kilojoules required daily is represented in the following table:

Age	Male	Female
12-15 years	10 900 kj	9 550 kj
16-18 years	12 900 kj	10 200 kj
19-50 years	11 550 kj	9 300 kj
51-70 years	10 450 kj	8 800 kj
Adults over 70 years	9 450 kj	8 300 kj

Source: NHMRC, Canberra. These figures represent average requirements for the Australian population. Actual energy needs for individuals will vary considerably depending on activity levels, body composition, state of health, age, weight and height. 

This follows the same sorts of levels as I might expect of an average, active person, lying as it does between the "sedentary 8700kJ" and the "active serviceman 17,640kJ", and well above the "marooned on a lifeboat 3,333kJ" levels the USCG suggest.

So, how do you get that level of nutrition, and maintain it, with limited resources?

Prison-style nutra-loaf?

Stockpiles of MREs?

Mainstay Survival Rations?

Pemmican?
a truckload of 2280 kJ Quarter Pounders?


There are lots of choices out there, and it comes down to how you aim to prepare, what you are preparing for, and how you want to live, before and after a crisis comes.
