Kart, I’ve been more or less prepping for years. I used to buy things that were considered “good” for prep purposes but in reality I just don’t normally eat such foods. Many of them went to the food bank after a while.
Also in dire straits people often lose their appetites, and appetite fatigue can set it in with emotional stress and boring food or food you don’t like. Especailly dangerous for the elderly, pregnant women, children and those with heath problems.
So IMHO it’s best to store ONLY what you know you like and best if you eat it regularly already.
Me I have never brought anything because it is said to be good, with the exception of a few barter goods (Like tobacco)I only store what I know I will eat and with condiments to prepare it as many different ways as possible.
