The Army wants to see inside volunteers' guts after weeks of an all-MRE diet

The Army Research Institute of Environmental Medicine’s military nutrition division is asking volunteers to take part in a six-week study during which they’ll spend 21 days eating only MREs.

They say the goal is to learn what happens to the human gut on an all MRE diet, even though the veteran and active duty communities have already voiced their opinion through hilarious memes.

They even predicted what would happen on an MRE diet:

But the Army’s study is actually serious business. The engine of the human digestive process is large colonies of bacteria in the gut, and these bacteria populations are affected by what people eat.

Army scientists want to learn how to game that system, crafting new MRE items that will make soldiers more healthy and resilient in the field. An area of particular interest is how to help the naturally occurring bacteria fight off food poisoning.

“We think we can manipulate the bacteria in a way that helps the bacteria fight foreign pathogens — things that could cause food-borne illness, for example,” the head of the study, Dr. J. Philip Karl, told Army Times. “Oftentimes, war fighters are overseas and they eat something off the local economy that can cause [gastrointestinal] distress. Potentially, what we could do by increasing the amount of beneficial gut bacteria is to help prevent some of that.”

Volunteers will have their gut bacteria populations measured on a regular basis as they proceed through the study, allowing researchers to see how the bacteria is affected. Hopefully, the researchers can then tweak the recipes and menus to make them better for troops.

As some vets still idolize the MRE lifestyle, the Army will likely have plenty of volunteers:

But they only want 60 volunteers and only ones who can travel to their facility in Natick, Massachusetts.
