Nutrition Basics for Survival

Understanding the importance of macronutrients

Macronutrients refer to nutrients that the body requires in large quantities. These are proteins, carbohydrates and lipids. In a survival situation, it is essential to maintain an adequate balance between these three elements to maintain normal body functions.
THE proteins contribute to the construction and repair of body tissues. They can also serve as a source of energy when there is a shortage of carbohydrates and lipids. Animal sources such as meat, fish, eggs and dairy are rich in high-quality protein.
THE carbohydrates are the body’s main source of energy. When you’re in a survival situation, it’s best to focus on complex carbohydrates (such as whole grains and vegetables) that provide a sustained release of energy.
THE lipids provide a concentrated source of energy and are essential for the absorption of certain vitamins. In a survival situation, lipids can come from nuts, seeds, fatty fish and oils.

Maintain micro nutrition

In addition to macronutrients, it is crucial to consume a variety of micronutrients. These include vitamins and minerals, which are essential for immune system support, bone health, metabolism, and other bodily functions.
Here are some examples of important micronutrients and their food sources in a survival situation:

  • Vitamin C: wild berries, green leafy plants, citrus fruits
  • Vitamin D: sun, fatty fish, enriched dairy products
  • Calcium: dairy products, nuts and seeds, green leafy plants
  • Iron: red meat, fortified cereals, green leafy vegetables


Water is the most critical nutrient in a survival situation. The human body can survive weeks without food, but only a few days without water. Make sure you have reliable methods of obtaining safe drinking water on hand, whether through rainwater harvesting, purification or desalination.

Survival food reserve

It is recommended to equip yourself with emergency supplies to deal with a survival situation. Among the brands to favor, we will note the products MRE (Meals, Ready-to-Eat), THE Datrex survival energy bars or the packs Wise Food Storage.
Make sure these stocks are nutritionally balanced, easy to prepare, and have a long shelf life.
Finally, remember to rotate these stocks regularly to ensure freshness and food safety.
A good understanding of survival nutrition principles can seem intimidating at first. However, with a little preparation and knowledge, you can ensure your survival and that of your loved ones in the most difficult situations.

Choice of Food: What to Eat in an Extreme Situation?

1. Energy-Rich Foods

In a survival situation, high-calorie foods become essential. They provide the energy needed to complete important tasks and combat exhaustion. Peanut butter, for example, is a rich source of protein and healthy fats. THE Skippy peanut butter offers approximately 190 calories and 7 grams of protein per 2 tablespoon serving.

2. Shelf-stable foods

Non-perishable foods are essential in a survival situation. Here are some options:

  • Canned food – meat, fruit, vegetables, soups (e.g. canned soups Campbell)
  • Whole grain cereals – oats, quinoa, brown rice
  • Dried products – beans, lentils, chickpeas

3. Easy-to-Prepare Foods

In a crisis scenario, it is likely that you will not have access to a full kitchen. Ready-to-eat or easy-to-prepare foods, such as freeze-dried foods, become very useful. THE Mountain House Freeze Dried Meals are a good example – simply add hot water, wait a few minutes and you have a complete meal.

4. Nutrient Supplements

Consider adding supplements such as multi-vitamins to your food supply. Make sure you have a reliable source of vitamin C (such as effervescent tablets Redoxone) to help prevent scurvy, a disease caused by a deficiency of this vitamin.

5. Foods for morale

Don’t overlook the importance of pleasure when selecting your survival foods. A little bit of chocolate, tea bags or coffee can bring comfort in difficult situations.

Food Calories Proteins Sustainability
Skippy Peanut Butter (2 tablespoons) 190 7g 2 years
Campbell soup (1 can) 80-300 3-14g 2-5 years
Mountain House Freeze Dried Meals (1 serving) 240-800 5-40g 30 years

So, make wise choices when it comes to food to survive in extreme situations. Be prepared, stay informed, and stay alive.

Preserving your Nutritional Health in a Survival Situation

Detailed Understanding of Your Nutritional Needs

The Key Role of Macronutrients

Macronutrients are the main nutrients necessary for human survival: proteins, carbohydrates and lipids. Each macronutrient has a unique and essential role:

  • THE Proteins help with cellular repair and are crucial for building muscle strength.
  • THE Carbohydrates are the body’s main source of energy.
  • THE Lipids (or fats) provide long-term energy and facilitate the absorption of certain vitamins.

The Essential Role of Micronutrients

Micronutrients, while necessary in small amounts, are just as essential to your health. Vitamins and minerals help with various bodily functions and maintain the strength of the immune system.

Plan Preventively

The constitution of Stock

In a survival situation, reliable access to food is not guaranteed. Make sure you have a suitable food stock. Ideally, set aside shelf-stable foods that meet your nutritional needs.
Foods that can meet these requirements may include things like:

  • Mountain House, for complete freeze-dried meals.
  • Canned foods Bonduelle, such as vegetables and fruits.
  • Cans of tuna or sardines Constable.
  • Whole grain cereals Nestle.

Water: The Vital Element

Consider your fluid source. Dehydration can quickly put your life at risk. Keep drinking water available and consider purification methods in case of shortage such as using LifeStraw, a personal water filter.

Adapt your diet

Portion Management

In a survival situation, the amount of food may be limited. It is therefore crucial to manage your portions well. Be sure to balance your meals with an adequate distribution of macronutrients.

Reasonable Consumption

Be aware of your energy costs. If you are moving or exerting yourself, you will need more food. Otherwise, conserve your food reserves and only eat when you are hungry.
This guide is designed to give general advice on nutrition in a survival situation. However, dietary needs can vary greatly from person to person. Make sure you have a good understanding of your personal needs and plan accordingly. This is when you will be fully prepared to stay healthy, even in a survival situation.
