Eat what you store and store what you eat is unrealistic.
We have some normal canned goods stored to ease the “transition shock” into the longer storage food types. Additionally, we will need to supplement our diet with both garden and wild plants, possibly wild fish and small game. This means eating foods, using recipes and cooking methods that we are not used to. Most of our food stores are ingredients and components to make meals. This was done to give us a more adaptable meal planning that our various cooks (and student cooks) can exploit. When all the stored food is gone (9 to 12 months, I hope), we will be eating only what we can grow, forage or catch and I guarantee, this will be a radical change in diet and the quantity calorie.
In using foods that storage very well, we will, of necessity, need to consider various grains and grain products. Nutritionally, I would prefer it to be otherwise but we will need the supplied calories. A single 1 pound loaf of bread (or noodles, pasta etc) has over 1500 calories. We are not currently used to eating that much bread each day but in the past it was a standard part of most of the world’s people for many centuries and it maybe again under EOTWAWKI circumstances.
Not wanting to eat certain foods because you do not like them will not acceptable under EOTWAWKI circumstances. If it has calories, vitamins and minerals or protein it is nourishes food. I have tried to eat things that I do not like or whose taste is unknown in the attempt to broaden my pallet. You need to remember the 15 x rule used in teaching children to try and learn to eat new foods. Some times it takes just tasting small amounts of a new food to learn to eat it. This also applies to long out of date foods. I have personally eaten them and while the loose flavor and texture (and probably nutrients) but where certainly eatable and retained calories. In a survival situation, being a picky eater is very dangerous to you. You may have to just eat the rat kabobs and bitter weeds if need be to stay alive. It takes some discipline but I have confidence that real preppers can do it.
While I do not think that going to get food poisoning is, necessarily, a given, however, between eating foraged foods and the lack of refrigeration, it is a highly possible event. Have a good supply of Imodium, medicinal clays, activated charcoal, ipecac and other OTC meds.
Many long term storage plans supply 2000 calories per person per day which is woefully inadequate for doing anything besides meditation. Having 3,000 calories per person per day, the bare minimum for an adult in an active survival situation, is better. Hard physical labor, especially in cold weather, will requires 4,500 and even 5,000 calories per adult per day would be better for occasional very strenuous and prolonged bitter cold situations.
