Hi Lisa, there’s lots of debate about this and the honest answer is – nobody knows for sure. It depends on the type of EMP, the frequency, how far away from the initial blast you are etc etc. We have an extremely in-depth post which goes into all of this if you want to dig deep on this subject – https://www.primalsurvivor.net/emp-protection-preparation/
I rotate my storage a lot and used it last year when my husband was laid off. What I found is that I prefer smaller cans because I usually don’t need larger sizes. We have three kids left at home at this point. We still only cook for 5 people, one meal at a time and if you are in a situation where you don’t have refrigeration you may not want to have to store the large can leftovers.
Also, include a good supply of the spices you like to cook with. These flavorings and spices allow you to do many creative things with your grains and beans. Without them you are severely limited. One of the best suggestions I can give you is buy a good food storage cookbook. Go through it and see what your family would really eat. Notice the ingredients as you do it. This will help you more than anything else to know what items to store.
Still, Jennifer says her preps helped her family get through the initial aftermath. Because she’d stored about three days’ worth of food in each of the bedrooms in her house, they were able to get by until a friend in the States sent additional supplies. As month after month rolled on with no running water in the region, the rain-catching and filtration system she’d set up also proved life-saving — especially amid concerns about contaminated water on the island and the mainland’s notoriously slow-moving and inadequate relief efforts.
We liked the Rice Pilaf because it had actual vegetable content! Whole peas and large slices of carrot. No other company has this much vegetable content, not even Mountain House. With chicken broth, white rice, and a surprising addition of orzo, this meal was excellent, especially with some of the freeze-dried chicken included in the Premier bucket.
