Dehydrated foods have several good qualities. They are easy to store, just keep ’em dry for the most part. Most varieties rehydrate well. Usually, there is very little nutritional loss during the dehydration process. Some kinds can be eaten without rehydration, such as dried fruits. They are also light and easy to toss into a bug out bag.
However, as with anything else, you gotta take the good with the bad. Most kinds of dehydrated foods require water to prepare. Clean, potable water might very well be in short supply when you end up needing your dehydrated foods the most. Crunchy lasagna noodles with powdered sauce mix doesn’t taste all that great without the added water.
Many of the entree varieties need not only water but it must be hot. So not only do you need to have a supply of potable water but you’ll need a way to heat it for a length of time. Again, might not be all that feasible during the greatest need for the food.
They are relatively expensive. You could easily spend $50-100 on a case or two of meals, receiving enough food for a family of four to last a couple days. For that same price, I could buy enough fresh food to last a couple weeks or more and can or preserve it myself.
While many varieties taste pretty good, sometimes the texture is a bit off. This isn’t a big deal as, if you’re hungry enough you’ll eat it. But, it is something to keep in mind. If you are going to store dehydrated food, I highly recommend you try them out first and be sure you like them.
Suffice to say, before you drop a few hundred bucks or more on some cases of dehydrated food, do your homework first. I’m not saying they are a bad thing. I have several packages myself. But, know ahead of time what is required to prepare them and be sure you will want to eat the ones you buy.
