This was the survival food of our ancestors, and it can still feed us well today—for cheap. Here’s the problem though, you’ll have to know (or learn) how to cook from scratch. Staple foods like pasta, rice, flour, dried beans, and sugar are easy to store and very affordable. Yes, you’ll need plenty of water to prepare the foods, but the best staple foods only require boiling to prepare. From the right supply company, you can purchase these foods pre-packed in plastic buckets with Mylar liners or in metal cans. These should all include oxygen absorbers inside, which will draw out oxygen and create a vacuum in the food container—allowing surprising longevity of the food (30 years or more, under ideal storage) with no significant nutrient loss. You can save even more money by purchasing your own dry goods, Mylar bags, and oxygen absorbers in bulk, then packaging the food yourself. In general, a five-gallon bucket usually holds over 30 pounds of dry goods, which contains more than 40,000 calories.
