Quick Answer
To determine serving sizes for long-term food, calculate individual caloric needs based on age, sex, weight, and activity level, then divide the total daily calories by 3-4 to determine the number of meals. Use a food scale to measure dry goods, and consider portion sizes for canned and processed foods. Plan meals around staple ingredients.
Calculating Caloric Needs
To determine serving sizes, first calculate individual caloric needs based on age, sex, weight, and activity level. A general estimate is 2,000 calories per day for women and 2,500 calories per day for men. Multiply this number by 365 to determine the total annual caloric needs, then divide by 365 to determine the daily caloric needs. For a prepper pantry planning for one year, assume 200,000 calories per person.
Measuring Dry Goods
When measuring dry goods, use a food scale to ensure accurate measurements. A general rule of thumb is to store 1-2 pounds of dry goods per person per week. For a prepper pantry planning for one year, assume 52-104 pounds of dry goods per person. Consider staple ingredients like rice, beans, and pasta, which can be used in a variety of meals.
Portion Sizes for Canned and Processed Foods
For canned and processed foods, consider portion sizes based on the product label or online research. A general estimate is 1-2 cups of canned goods per meal, and 1/4 to 1/2 cup of processed goods per meal. Plan meals around staple ingredients and supplement with canned and processed goods as needed.
