Great post, Bee!
However, just in case I'm one of those folks that God has decided will be on this earth for awhile - despite disasters, man-made or natural, I'm going to use my God-given intelligence, strength, and perseverence to try and make my life, and the lives of my loved ones as comfortable as possible while we are on this earth. (whew...run on sentence, lol)
I am reminded of the story of the man in a flood who is waiting on God to save him:
"A man is sitting on his porch as flood waters rise. A woman floats by in a boat, asking if the man needs help. "No, thank you," says the man, "I'm trusting in the Lord." The waters rise higher, sending the man upstairs. A raft full of people floats by his second story window. "Get in," they say, "there's plenty of room." "No thanks," says the man, "I'm trusting in the Lord." The flood waters keep rising, pushing the man up to the roof. A helicopter swoops in, lowering its ladder for the man. "Thanks anyway," shouts the man, "I'm trusting in the Lord." Finally, the man is swept away in the torrent and drowns. At the gates of Heaven, the man asks God, "Why didn't you save me?" "What do you mean?'' replies God, "I sent two boats and a helicopter."
Do I have animals, water collection, a well-stocked pantry? Yes. I won't watch my children or grandchildren suffer if I can prevent that. I don't think I'm obsessive, or 'over the top' I just hope that I can make lives a little easier in the event of a major challenge.
I know we have drifted off topic a bit here...this topic is about what food stuffs we think are essential:
Water, salt, sugar, honey, booze (for barter and other different and various reasons, lol). Staples such as rice, pasta, beans. We don't eat much bread so I wouldn't add wheat to my list. I don't particularly love canned food, but I do buy some to keep on hand. I have a nice garden, and I do can the produce, but some years are better than others. Some powdered milk even though I have goats because they might not be lactating or they might not survive a disaster.

A small amount of packaged potato products...some canned meat. Even though I absolutely barf at the thought of Spam in most instances I will tell you that a skillet full of fried potateos, onions and Spam can be might tasty cooked over a campfire! Canned fruit and juices for a treat. DH and I don't normally eat 'em, but if fresh were unavailable some canned fruit (packed in water or natural juice) would be nice. I rotate my stock when the grandkids come by making fruit salad for them. They're young enough that if you put some whipped cream on top they'll eat anything, lol! Canned soups because they are a meal in a jar/can. We have homemade and commercial soup on hand.
I don't have years and years worth of stuff on hand. My basic preps are for small, local type challenges that are usually weather related. I don't forsee a breakdown of society of major proportions in my lifetime (I know, I know - rose colored glasses here). But I fear for my kids and especially my grandkids.
I can't even try to prep for something as major as a nuclear disaster - so in that case I wanna follow Bee's lead and be prepared for eternity. Well, I try to prepare for that daily - no disaster needs to threaten for that. I try to live my life every day as if it could be my last. Our community lost a child this week. That's a tragedy, but even worse is that she and her mom were fighting - she left the house angry and was walking to her aunt's house when she was struck by a car. Her mom - knowing that her last words to her daughter were spoken in anger - had to make the decision to remove life support from her child. I cannot imagine the pain and anguish that mother is going through. My heart goes out to her.
What this comes down to is that I'm simply doing as much as I can do to try and keep my family comfortable in an uncomfortable time.
