People can get quite uncivil when starving or in trouble therefore force multipliers like night vision/thermal scopes using solar recharged batteries on suppressed rifles can let you avoid trouble or end a threat like nothing else can. Walkie talkies with ear buds and whisper microphones can also be force multipliers. That equipment should be protected in faraday cage. An early model (EMP resistant) diesel tractor with fuel can help grow food and offer transportation (with a wagon) and might save the day for your family or community.
I think the author adds in the high processed food for variety. He clearly states that the stew would be for a time when you couldn’t cook a real meal. some of the others could be eaten in an emergency when there was no way to cook such as the ravioli ect.

But a new year is really just another twelve-month slice of the future, and it contains dangers as well as opportunities. Obviously we hope none of the bad things the future can hold will come to pass, but we have to be realistic – the world isn’t always a friendly place.

The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
Though its light weight and long shelf life are ideal for navigating harsh conditions, freeze-dried food is probably most famous as a cultural curiosity: Like many Americans, I discovered it in a museum gift shop, gawking at the styrofoam-like ice cream that astronauts used to have for dessert. More recently, I encountered it at a disaster preparedness convention in Raleigh, North Carolina, where smiling, gray-haired preppers manned tables piled with plastic bags full of vegetables, meats, and stews.
