Water is very important. I keep 6 months worth on hand for me, my wife, three dogs and two cats. You will want to make sure you're getting all the nutrients you need and too much of something from such a narrow diet. Freeze dried food is generally considered the most shelf stable and nutritious. It's expensive and requires rehydration. Canned might leave holes in your nutrient profile but it's cheap and lasts years. Maybe consider a multivitamin. Bags if beans and rice are cheap but maybe harder to store long term and very bland and again you'll become nutrient deficient from such a narrow diet. Only you can know your needs but in addition to six months of water we keep six months of dog and cat food. Nine months of freeze dried food buckets under beds. 12 gallons of alcohol fuel - it burns super clean and has an indefinite shelf life.

Our goal is to be able to lock the gate and stay home for 6 months in a grid down scenario. Think about how long you'll be on survival resources, in what conditions and calculate how much each individual needs. The longer you go the more money you need. Start right now, prepping is a process and you will need to budget, buying a bit each pay check or monthly.
