2. Calculating Food and Water Requirements
Water
The general recommendation is to have at least one gallon of water per person per day for drinking and sanitation. For a family of four, this equates to:
1 gallon/day × 4 people × 90 days = 360 gallons of water
You can store water in large barrels or multiple smaller containers. Ensure that the containers are food-grade and stored in a cool, dark place to prevent contamination.
Food
When planning your food stockpile, aim to include a balance of proteins, carbohydrates, fats, and essential nutrients. Here’s a guideline to help you determine quantities for a three-month supply:
Grains and Cereals: Aim for 15-20 pounds of grains per person per month, which includes rice, pasta, and cereal. For four people over three months, you will need:
20 pounds × 4 people × 3 months = 240 pounds of grains and cereals
Proteins: Include a mix of canned meats, dried beans, lentils, and nut butters. Aim for about 1 pound of protein per person per day. For a family of four, this equates to:
1 pound/day × 4 people × 90 days = 360 pounds of protein sources.
This includes:
- Canned meats (like chicken, tuna, or beef): 120 pounds.
- Dried beans and lentils: 120 pounds.
- Nut butters (such as peanut butter): 30 pounds.
- Powdered eggs or shelf-stable milk: 90 pounds.
Fruits and Vegetables: Include a variety of canned or freeze-dried options. Aim for about 1.5-2 servings of vegetables and 1 serving of fruit per person per day.
For four people:
Vegetables: 2 servings/day × 4 people × 90 days = 720 servings. Convert this to approximately 200-300 cans of vegetables.
Fruits: 1 serving/day × 4 people × 90 days = 360 servings. This is roughly 150-200 cans of fruit.
Fats and Oils: Essential for cooking and maintaining energy. Stockpile about 1-1.5 gallons of cooking oil per month per family.
Condiments and Spices: These add flavor and variety to your meals. Include salt, pepper, sugar, dried herbs, and other spices. Aim for about 5-10 pounds of various spices and condiments.
