The Food Survivability Index

The Food Survivability Index is a standardized scoring system that evaluates how well a food or prepared meal supports healthy, affordable, and sustainable daily living over the long term. By measuring eight key factors—cost, taste, nutrition, food additives, flexibility, convenience, storage ability, and waste—it provides a practical way to compare foods and make better decisions about purchasing, preparing, and storing meals for everyday use and emergency preparedness.

Developing a Food Survivability Index is an excellent way to make informed decisions about the foods we purchase, prepare, store, and consume. Rather than selecting foods based primarily on price, taste, or convenience, a standardized scoring system allows us to evaluate their overall ability to support healthy, sustainable living over an extended period. By considering eight important factors—cost, taste, nutrition, food additives, flexibility, convenience, storage ability, and waste—we can identify foods that offer the greatest long-term benefits. Such a system encourages us to look beyond immediate satisfaction and consider how well a particular food contributes to our health, financial stability, food security, and ability to maintain a dependable daily diet.

A numerical scoring system also makes it easier to compare different foods objectively and identify their strengths and weaknesses. For example, a commercially prepared frozen dinner may offer excellent convenience but score poorly on cost, sodium content, or storage requirements. A homemade meal may provide better nutrition, fewer undesirable additives, lower cost, and greater flexibility, but require additional preparation time. Similarly, dried beans and rice may offer excellent storage ability and economy but require water, fuel, and cooking equipment. Assigning scores to these characteristics allows us to recognize such trade-offs and select a balanced combination of foods rather than relying on any single product or food category.

Perhaps the greatest benefit of a Food Survivability Index is its usefulness in developing a sustainable long-term eating strategy. Good nutrition must be maintained not just for a few days, but throughout months and years of daily living. Foods must be affordable enough to purchase regularly, enjoyable enough to eat consistently, nutritious enough to maintain health, and practical enough to store and prepare without excessive waste. During emergencies, the importance of these characteristics becomes even greater. By using a consistent scoring system, individuals and families can gradually improve their food choices, reduce unnecessary expenses, maintain more reliable food reserves, and build a healthier, more resilient food supply. The index is not a guarantee of nutritional adequacy or survival, but it provides a practical framework for making better everyday decisions that support long-term health, independence, and food security.

We first give our 8 key survivability factors a weight based on it,s importance to surviving day to day

Factor	Weight	What to Consider
Cost	15	Cost per serving and calories per dollar
Taste	10	Will people willingly eat it regularly?
Nutrition	20	Protein, fiber, vitamins, healthy fats, and overall balance
Food Additives	10	Artificial ingredients and excessive sodium
Flexibility	10	Ability to substitute and use ingredients in many meals
Convenience	10	Ease of preparation and cleanup
Storage Ability	20	Shelf life, resistance to spoilage, and storage requirements
Waste	5	Packaging waste and likelihood of unused food being discarded

0 to 100	Grade
90-100	Exceptional preparedness food
80-89	Excellent choice
70-79	Good choice with minor compromises
60-69	Acceptable but not ideal
50-59	Significant weaknesses
Below 50	Poor survival value
