Accetta confirmed the gum in MREs is not a laxative but a gum with xylitol in it, which helps with oral health and hygiene in the field. A once-believed myth was finally debunked — or was it?
According to the 2016 study, the MRE is reported to have no negative effects on gut health and only a “small” impact on the gut microbiome.
Some chewing gum labels may contain a warning about a possible laxative effect. When some bulk sweeteners such as sorbitol and xylitol are consumed at high levels – either in chewing gum or other food products – some consumers may experience a mild laxative effect. 1.
However, as a general rule, MREs are high in protein and carbohydrates, but low in fiber. They also tend to be high in sodium, which can cause dehydration and constipation if not properly balanced with adequate water intake.
Some people have mild nausea, cramping, or diarrhea from the contrast material or other items injected ingested. Let your healthcare provider know if you have any serious or ongoing discomfort.

The shelf life is highly related to the storage temperature. For example, if stored at 120 ºF or 48.9 ºC (a temperature that could be encountered on desert battlefields), the MRE should be used within a month. Stored at 60 ºF (15.6 ºC), an MRE can last 7 years or more.
And that is often the case in the field. He added that the 2004 Joint Services Operational Ration Forum chose to put xylitol gum in the MRE packages. It went into production in 2005 and is still given to service members to prevent stank breath today. Previously, the gum was just a sugar-based chewable.
All of these factors can affect the gut microbiome and gut function. "We found that the MRE does not increase gut leakiness, does not appear to negatively impact gut health, and has only subtle effects on the gut microbiome in people eating the MRE while going about their normal daily lives."
He noted that it's also possible to lost weight on the MRE diet: Soldiers in Ranger school typically complete grueling training on just one MRE per day and can lose 35 pounds or more in the process.
Taking guar gum by mouth seems to relieve constipation in some adults and children.
Prunes and prune juice live up to their reputation as foods to help constipation due to a unique ingredient. In addition to fiber, prunes are rich in a naturally occurring sugar alcohol called sorbitol.
Explosive, or severe, diarrhea can be forceful. It happens when the rectum fills with too much stool or gas, which results in the body expelling the diarrhea or gas suddenly. Diarrhea is often the result of viral or bacterial infection, sometimes after eating contaminated food.
Each piece of military caffeine gum contains 100 mg of caffeine, which is about the amount found in a six-ounce cup of coffee.
After adjusting for baseline scores, mean IBS-SSS scores during and after INT were higher in MRE relative to CON (Table 2). However, the clinical significance of that difference was likely minimal, as the incidence of “mild IBS” did not differ between groups at any time point.
MRE's have very high sodium
On average, the sodium content for a single MRE is a whopping 3800 milligrams! The high-fat (averaging about 52 grams of fat, 5 grams trans fats) and high-salt content are less than ideal for sedentary situations.
As a result of earlier unauthorized sales to civilians, the Department of Defense requires that "U.S. Government Property, Commercial Resale is Unlawful" be printed on each case of MREs. The warning is only intended for service members as there are no laws that forbid the resale of MREs by civilians.
This intestinal traffic jam, the authors concluded, is largely attributable to the MRE's lack of good bacteria found in the sort of fresh foods, such as fruit or yogurt, that provide the extra nudge the bowels need for a satisfactory release.
The increased concentration of xylitol in the digesta leads to an increased osmotic pressure which contributes to water retention in the digesta and thus may lead to laxative effects when consumed in excess (>20 g) [8,24].
Through a series of trials _ including one that counted the drips of saliva that flowed from tubes placed on the subject's salivary glands into a beaker when gum was chewed and when it wasn't _ researchers discovered that gum moistened mouths, improved concentration and calmed nerves _ essential traits on the ...
A long time, I've eaten MREs that were over 20 years old. But I would say around 5 years and they are safe. Just make sure the packet you open is not already open, keep in a safe area not below O degrees and not over 120 degrees. I use these for camping, boating and emergency use.
The Verdict? When it comes to macronutrients, particularly protein, MREs are a healthy choice and offer a much better balanced energy profile than typical emergency meals. However, like most emergency meals, MREs aren't healthy when it comes to micronutrients, sodium, and fiber.
