Is MRE Food Healthy for Civilian Use?

4 min read

While MREs were specifically designed to sustain soldiers during intense activity, providing approximately 1,250 calories per meal, their health implications for everyday civilian use are far more complex. The question, 'Is MRE food healthy?' depends heavily on how and when it's consumed.

Quick Summary

Meals, Ready-to-Eat (MREs) are high in calories, sodium, and preservatives, but low in fiber, which makes them suitable for short-term, high-intensity situations rather than sustained civilian consumption. Their nutritional value degrades over time, so they are not a substitute for a balanced, fresh diet for long-term health.

Key Points

  • Intended Purpose: MREs are designed for high-energy, short-term military use, not as a long-term civilian diet.

  • High Calorie and Sodium: They contain approximately 1,250 calories per meal and high sodium content, which can be excessive and unhealthy for sedentary individuals.

  • Low Fiber: The low dietary fiber in MREs is a well-known cause of constipation and digestive issues with prolonged use.

  • Nutrient Degradation: Vitamins fortified in MREs degrade over time and with exposure to heat, so they are not a reliable source of micronutrients.

  • Supplement for Health: Civilians should supplement MREs with high-fiber foods, multivitamins, and electrolyte packets for better long-term health in emergency situations.

  • Not a Survival Staple: While good for a few days, MREs are not a substitute for a balanced, fresh-food diet for sustained health and wellness.

Meals, Ready-to-Eat (MREs) have earned a reputation for reliability in emergency situations, offering a self-contained, shelf-stable source of calories. However, what makes them ideal for a soldier on a multi-day mission doesn't necessarily translate to a healthy food choice for a civilian. The answer to 'Is MRE food healthy?' requires a detailed look at their nutritional makeup, intended purpose, and long-term effects on the body.

The Nutritional Profile of an MRE

MREs are meticulously engineered to provide maximum calories in a compact form, ensuring a soldier has enough energy for strenuous activity. A single MRE contains roughly 1,250 calories, with a macronutrient breakdown that's intentionally heavy on carbohydrates and fats for sustained energy. While this is beneficial for a person expending thousands of calories a day, it's excessive for someone with a sedentary lifestyle.

The Good: Macronutrients and Fortification

  • High Calorie Count: MREs are excellent for their intended purpose—providing energy during demanding physical activity.
  • Balanced Macronutrients: They offer a decent ratio of carbohydrates, fats, and protein, although the sources are highly processed.
  • Fortified Vitamins and Minerals: Many MREs are fortified with essential vitamins and minerals like iron, zinc, and vitamins A and C to combat potential deficiencies in the short term. However, heat exposure and long-term storage can degrade vitamins.

The Bad: Sodium, Fiber, and Additives

  • High Sodium Content: One of the most significant health concerns is the extremely high sodium content, which can average over 3,800mg per meal—far exceeding the recommended daily limit for most people. This can lead to dehydration and increase the risk of high blood pressure.
  • Low Fiber: MREs are notoriously low in dietary fiber, leading to the infamous nickname 'Meals, Refusing to Exit'. This can cause constipation and other gastrointestinal issues if consumed for more than a few days.
  • Processed Ingredients: To ensure a long shelf life, MREs are filled with preservatives, stabilizers, and artificial additives. These ingredients are not ideal for long-term health and can compromise nutritional value.

MREs vs. Whole Foods and Emergency Alternatives

To understand whether MREs are a 'healthy' choice, it's helpful to compare them to other food options, especially for emergency preparedness.

Feature MREs Whole Foods (Fresh/Dehydrated) Freeze-Dried Meals
Purpose Short-term, high-energy military use Optimal long-term health Long-term storage, lightweight for outdoors
Shelf Life ~5 years (degrades faster in heat) Days to months 15-30+ years
Nutritional Profile High sodium, low fiber, fortified vitamins (degrade) Balanced nutrients, high fiber, fresh vitamins Retains most nutrients, low sodium options available
Taste & Variety Highly subjective, some notorious for poor taste Excellent, vast variety Generally good, decent variety
Cost Expensive per meal, not cost-effective for everyday use Can be affordable Generally cost-effective for long-term storage
Preparation Ready-to-eat with included heater Requires cooking Add hot water
Best For Survival situations, extreme physical exertion Daily life, sustained health Long-term emergency food supply

The Effects of Long-Term MRE Consumption

While the U.S. military recommends limiting exclusive MRE consumption to 21 days, some individuals have consumed them for much longer. This practice is associated with significant health concerns, including nutrient deficiencies, weight loss due to poor caloric intake, and continued digestive problems like constipation. For the average civilian, prolonged reliance on MREs could lead to negative health consequences such as high blood pressure and an imbalance in the gut microbiome. An Army study, however, found no negative effects on gut health from a 21-day period of MRE consumption. This highlights that occasional use is not harmful, but long-term reliance is unwise. The key takeaway is that MREs are a survival tool, not a dietary staple.

How to Supplement MREs for Better Health

For civilians using MREs for preparedness, supplementing them is the best way to mitigate their unhealthy aspects. To balance the high sodium and low fiber, consider adding the following to your emergency stash:

  • High-fiber snacks: Stock up on dried fruits, freeze-dried vegetables, and whole-grain crackers to promote digestive health.
  • Electrolyte packets: Combat dehydration from high sodium intake by adding electrolyte powders to your water.
  • Multivitamins: Since heat and age degrade the vitamins in MREs, a separate supply of multivitamins can ensure you're getting essential micronutrients.
  • Healthy fats: Incorporate shelf-stable nuts and seeds to add healthy fats to your diet.

Conclusion: A Tool, Not a Diet

The ultimate answer to whether MRE food is healthy is that it is healthy for its intended, short-term use in high-stress, high-energy situations. For the average civilian, relying on MREs for more than a few days can lead to negative health consequences due to high sodium, low fiber, and a reliance on processed ingredients. While they are an invaluable resource for emergency preparedness, they should be supplemented with other foods for sustained nutrition. For long-term readiness, a varied supply of dehydrated and freeze-dried foods, along with fresh foods when available, is a far healthier option.

A Final Word on MREs

MREs are a survival ration designed for function over health. Use them for their intended purpose—a few days at a time during an emergency—and supplement them to protect your long-term wellness. Additional information on MREs and survival food storage can be found at MREInfo.com.

Frequently Asked Questions

Yes, it is possible to survive solely on MREs for a short period, typically up to 21 days as recommended by the military. However, long-term exclusive consumption can lead to nutritional deficiencies, weight loss, and digestive problems.

The high sodium content is designed to replenish salts lost by soldiers during intense physical exertion and to act as a preservative for long-term storage. For less active individuals, this level of sodium is dangerously high.

Yes, prolonged consumption of MREs is known to cause constipation. This is primarily due to their low dietary fiber content, which is necessary for healthy digestion.

The initial vitamin fortification provides a good nutritional start, but vitamins are not shelf-stable. They degrade over time, especially with exposure to heat, making MREs unreliable as a long-term vitamin source.

MREs have an official shelf life of about five years when stored in optimal, cool, dry conditions. Exposure to high temperatures significantly reduces this lifespan.

This depends on the situation. MREs are 'ready-to-eat' and require no additional water, making them better for immediate consumption. However, freeze-dried food is lighter, has a longer shelf life (15-30+ years), and is generally healthier, making it better for long-term storage.

Due to the high sodium, calorie, and fat content, MREs are not ideal for children or the elderly, who are more susceptible to the adverse effects of these ingredients. They should only be used as a short-term last resort.
