Makes MREs edible.
No, and a lot of what's said about MREs is urban legend (such as the gum being formulated to plug up the old rectum). Health problems... if you eat them habitually, they'll fatten you up rather quickly. MREs are intended to be eaten in a heavy work environment, and they contain some 2000 or calories.

Interesting question. Having experienced MREs when they were first introduced, I would have to say no. Quite the opposite actually. Those who eat MREs on a regular basis learn quickly to get bread and butter, a lot of butter from the field kitchen, and chase a few slices with a lot of butter with the MRE contents. I suggest keeping a couple bottles of magnesium citrate back at garrison for when you return from the field.

MREs didn't exist in World War I. They came along later.
Premade backpacker meals are good, and if you are a bit adventurous military MREs are not the worst way to go. Bothe require you to just add water, the backpacker meals the temperature of the water will affect the temperature of the food. With the MREs they come with heater packs that you add water to.

Yes, it is possible for scientists to create a dry "kibble" for humans. Like MREs for soldiers and astronauts, it would supply necessary nutrients. However, whether human or animal, taste buds crave variety. MREs aren't very tasty, just like powdered milk of the 1960s.
