Just be aware, if you have stored mixes like bisquick or cake mixes which have baking powder in them. Baking powder has a shelf life, after that shelf life, the bp isn’t stable so your product may not rise and/or may taste funny. Depending on what form of dry milk (powder as opposed to instant milk) is used, that can also make your premixes go bad.
Zombie apocalypse: Used by some preppers as a tongue-in-cheek metaphor[77] for any natural or man-made disaster[78] and "a clever way of drawing people’s attention to disaster preparedness".[77] The premise of the Zombie Squad is that "if you are prepared for a scenario where the walking corpses of your family and neighbors are trying to eat you alive, you will be prepared for almost anything."[79] Though "there are some... who are seriously preparing for a zombie attack".[80]
Don’t stop there. Take a hard look at demographics.  Are you in a city where gangs, mobs or terrorist attacks are likely?  Do you live in a remote area where the failure of transportation systems or the lack of fuel will cut you off from supplies arriving from the rest of the world?  Is your employment situation tenuous requiring that you build up some cash reserves to get you by just in case the job goes away?
This country is one of the safest in the world. We have no killer animals. We don’t have earthquakes. There are no major tsunamis. We don’t really have to prep for a huge natural disaster – and there’s very little you could do to prepare for a nuclear event even if you wanted to – so we prep more pragmatically. Suppose you lose your job and money’s an issue. Or the electrical grid goes out and the food chain goes down and all of a sudden every man and his dog is arguing over a bag of sugar. Do you have your own supplies? Do you have the means to cook? And what about keeping warm – could you make a fire? Some of us buy food through an app; groceries are delivered to our front doors. Do people know how to survive without electricity?

With that goal in mind, let me say this:  this is not a list of items intended for deep storage. Nor is it a list of items packaged so that they have a 25 year shelf life.  (And in reality, do you really need your stored food to last that long?)  I am also not going to list items that might be foreign to your palate, difficult to find, or too costly to absorb into your weekly shopping budget.
81. Potassium/iodide tablets – it’s wise to store Potassium iodide or KI in your medical emergency kit. This is a type of salt that cab be used to combat radiation poisoning. Potassium Iodide will block radioactive iodine from being absorbed by the thyroid gland. KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.
Survivalists' concerns and preparations have changed over the years. During the 1970s, fears were economic collapse, hyperinflation, and famine. Preparations included food storage and survival retreats in the country which could be farmed. Some survivalists stockpiled precious metals and barterable goods (such as common-caliber ammunition) because they assumed that paper currency would become worthless. During the early 1980s, nuclear war became a common fear, and some survivalists constructed fallout shelters.
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
