In her book Emergency food storage and survival, Peggy Layton wrote "We've all heard the saying, "You can't live by bread alone". I have the philosophy that you can live on bread and soup."

I think it's interesting. Learn to make your own bread with wheat, yeast, powdered milk and dried eggs etc. For soup you have instant bouillon beef and chicken, dehydrated soups and canned soups, stuff like that. You start with it and then you can expand your array of food. Of course you already pack a lot of water because it's not a challenge to store water, it can withstand extreme temperature fluctuation but just make sure to protect them from light.

For the backpacker and bug-out situations it's another matter of course. Chris K. made me aware of an interesting text by Brenda L. Braaten "Pack light, eat right". It has good information :
