Ester Dickey meant well, but her plan is very wheat intensive. Wheat is a labor intensive to prepare. Mrs. Dickey was Mormon and Mormons store large amounts of wheat as part of their contingency planning because Joseph Smith said to do so in the Doctrine and Covenants (one of the books in the Mormon canon alongside the KJV Bible and the Book of Mormom).
Excessive amounts of wheat can also be hard on the digestive and immune system, especially for the very young and very old. Like a lot of Mormon food storage plans, her plan is also very powdered milk intensive. If your ethnic background isn’t White European, then you could have a problem with that. Other races have a much higher rate of lactose intolerance that Whites do once a person hits puberty.
For an emergency stockpile, rice and lentils is a better choice. Together they supply most of the nutrients that you need. they store well and they go a long way. Rice doesn’t rely upon grinding and other time consuming, messy preparation methods. you just cook it. Lentils are the most nutritious of legumes (beans) and they are the only legume that doesn’t require pre-soaking when dry. They are also one of the least expensive legumes you can buy.
For a basic food supply rice and lentils, plus salt, a few inexpensive cooking spices from Walmart, multivitamins, tea, coffee, and drink mixes. Drink mixes are important in that they make crappy tasting but otherwise biologically safe water drinkable. Tea and coffee can do the same and are comforting. High citric acid drink mixes have a tangy taste that also covers up the taste of inexpensive veterinary oral antibiotics that come in a water soluble powder.
