Quick Answer
Calculating a one-year food storage supply involves estimating your daily food needs, multiplying by 365 days, and accounting for calories, nutrients, and personal preferences. A general rule of thumb is to store 1-2 pounds of food per person per day. This can be broken down into grains, proteins, fruits, vegetables, and fats.
Estimating Daily Food Needs
To calculate your daily food needs, consider your age, sex, weight, activity level, and climate. A general guideline is to consume 2,000 calories per day for adults and 1,500 calories for children and seniors. For example, a 30-year-old male weighing 150 pounds with a moderate activity level may require 2,500 calories per day. Multiply this number by 365 days to determine your annual food needs.
Calculating Food Storage Quantity
Assuming a 2,500 calorie daily intake for the 30-year-old male, you would need 912,500 calories per year (2,500 calories/day x 365 days). This translates to approximately 912 pounds of food per year (1 pound = 3,500 calories). To account for waste, spoilage, and varying food values, consider a 20-30% buffer, resulting in a total of 1,130-1,350 pounds of food per year.
Planning Your Food Storage
When planning your food storage, consider a balanced diet consisting of grains (250-300 pounds/year), proteins (100-150 pounds/year), fruits (50-100 pounds/year), vegetables (50-100 pounds/year), and fats (20-50 pounds/year). Store a minimum of 3-6 months’ worth of food initially and gradually build up to a one-year supply. Consider using MyPlate or other meal planning guides to ensure a balanced diet.
