What is the better choice for survival food? How do MRE, Freeze Dried Food (FDF), or storing canned food and bulk grains from the super market compare?

Below I have scored the options for disaster survival food against these factors;

• storage life
• storage space
• preparation time
• taste
• cost (per meal).

The scoring goal is to have an objective calculation. However the ratings are my subjective opinions, and are based on the facts and information I have been reporting in this blog. I have also added a second level score with a weight for each factor. Again, this is my opinion about the factor’s relative importance to a survival food strategy.

The weighted score total for the survival food options is out of 10.

It is also important to note that the scoring was based on a required food supply that will last 6 weeks to 3 months.

MRE would rate better in a 72 hour survival kit comparison with mobility and easy to heat as factors.

Here are the scores;

You can see that based on the way I have scored and weighted Freeze Dried Food is the superior choice especially for longer term preparedness of 6 weeks to 3 months. Since you may have different opinions you can evaluate the score and weight outlined here. I will add a poll shortly to get everyone’s opinion on the ratings for each of the factors and the factor weights. Then we can look at the results.

In the meantime I have also posted a link to the original excel file so you can change the weights and scoring your self as you wish and see the results. Here is the file link;

I have done some research and have some further comments of my own and clarifications on water storage. Thanks for the excellent article on water storage by Terry Fitzroy of Survival Solutions published in a previous post here on Bulk Survival Food.

There was a suggestion in that article that you should drink 8 glasses or 64 ounces of water a day. This is a myth so pervasive medical professionals sometimes say it. Medical journals found no research supports this anywhere and have traced the myth back to a mis-interpretation of a 1945 medical report.

The fact is most of the 64 ounces of water is contained in the food we eat. That is if what you are eating is a healthy well balanced diet. Read this British Medical Journal article that quotes the 1945 report “One origin may be a 1945 recommendation that stated: A suitable allowance of water for adults is 2.5 litres daily in most instances. An ordinary standard for diverse persons is 1 millilitre for each calorie of food. Most of this quantity is contained in prepared foods“.

Over time it appears most people, even doctors, have forgotten the key second sentence in bold above.

If you are eating MRE food reserve in a disaster, most of the 64 ounces (~2.5 liters) of the water is already in the food. If you use a Freeze Dried Food food reserve , you need store more water to hydrate the food when you eat, but the water you use to hydrate the food all ends up in your body when you eat it.

That said, then what is the real amount water storage needed for emergency preparedness?

The Red Cross and FEMA say one gallon of water per day in their “Preparing for Disaster” pdf (on page 8), but this for a “3 day supply kit”. So perhaps this does not include water requirements for hygiene? Does it assume you have also included in your 3 day kit mostly canned food that has water in the food as opposed dry grains and cereals which will need a lot more clean drinkable water to cook?

www.72hours.org offered this advice on water “Store one gallon of water, per person, per day. This amount will be adequate for general drinking purposes. Three gallons per person per day will give you enough to cook and for limited personal hygiene.”

They also advised to replace unopened stored bottled water once a year.

Perhaps you can plan to replace the water each year the day before or the day after your birthday so you will remember to do it. Or Perhaps we should have a “Preparedness Day” holiday so that we can do once a year whatever needs to be done that year like throwing out the canned food and bottled water and replace it with a new supply for another year. I am sure the food industry will be all for this holiday, they should take the cue from the chocolate and flower people for what they did to create Valentine’s day. Let’s move on.

So the answer, in terms of clean water storage for consumption, appears to be 1 to 3 gallons per person per day depending on whether you are using water for cooking.

If your survival food store is MRE then your requirement will be closer to 1 gallon per day, and 1.5 gallons if you use Freeze Dried Food.

You may think there is an advantage to MRE here but you will need the same if not more storage space for the same period of food support for MRE due to package density of MRE. As well you will always have more options in terms of water resource allocation as the additional water you store for Freeze Dried Food can be used for other purposes if it makes sense, while with MRE the water that is already in the food can’t be practically extracted out.

The best way to safely store water is in food grade containers like the ones below. With stabilizer applied and containers properly sealed water will be good to drink for 5 years. Click on the pictures of the containers to get more information on them;

30 gallon container, 4 per package at Nitro-Pak

55 gallon container, 4 per package at Nitro-Pak

What if you did not prepare water before an emergency?

Here is some excellent information from Public Heath of Seattle and King county on “How to prepare safe water after a disaster”.

MRE Informational Videos

I looked all over YouTube for some good video clips that show you what is in an MRE and features.

These were the best MRE videos I could find.
