Effects of Meal, Ready-to-Eat (MRE) Consumption on Gut Health
The objective of this study is to determine the impact of consuming MREs as the sole source
of subsistence for 21 days on gut bacteria community composition and gut health. Up to 80
free-living adults will be randomized to consume their usual diet or only MREs for 21
consecutive days. MREs will be provided by the Military Nutrition Division, US Army Research
Institute of Environmental Medicine (USARIEM). Fecal, urine and blood samples will be
collected periodically before, during and after the intervention to measure gut barrier
integrity, gut bacteria community composition, and markers of gut health, inflammation, and
nutritional status.
