Not all food items are packaged equally and this can create a problem for your long term food storage. Your long term food storage must be able to satisfy the daily needs of your family with a sufficient amount of calories to sustain required activity levels. The calorie content of your food storage items is one of the most important factors in having a proper food storage program.
Many people will consume close to 2000 calories in an average day. While performing strenuous activities in a stressful environment, there can also be an even greater need for additional calories in order to maintain necessary activity levels.
As an example of the difference, let’s look at a couple of simple food items for a comparison of calories that are available. A small 5oz. can of tuna which has been packed in water will normally have about 100 calories (2 servings of 50 calories...this is slightly higher if it is packed in oil). That’s not a whole lot of calories. On the other hand, a 15 oz. can of chili normally has around 400 calories. At this rate, you would have to eat 4 cans of tuna packed in water to get the same number of calories in the average can of chili. You would also be consuming approximately 20% more food by weight (20 oz. of tuna vs. 15 oz. of chili).
While activity levels may not always require a meal with high calorie content, it will be necessary to make sure you do have sufficient stocks of high calorie food items available if needed to supplement the energy needs of your body.
While having a variety of different food items is also important, you also need to make sure that you have food items with sufficient caloric value to satisfy the energy needs of your body. You need to keep a check on the amount of calories in your food storage program because calories are a direct measure of the fuel available to feed the energy needs of your body.
