"Store what you eat and eat what you store” is a popular adage of storing survival foods. The foods stored should be what a person likes to eat, and the foods should be eaten before they go bad and have to be thrown away.
“Store what you eat and eat what you store” has been cited in print since at least 1970.
23 March 1970, Idaho Falls (ID) Post-Register, “Conference Draws 1,444,” pg. 9, col. 3:
Emphasizing the importance of storing a year’s supply of food, President Pieper said “Store what you eat and eat what you store.”

We also want to be able to eat nutritiously during times of need when we use our food storage. It is only feasible, then, to “Store what you eat and eat what you store.”

Foods store best jn dry cool areas - preferably between 40 to 60 degrees - but no food can be stored forever: Thus the “store what you eat and eat what you store” adage.

Eat what you store,
store what you eat
OTTAWA (CP)—It can happen when you least expect it. You live alone and become ill or a severe winter storm keeps you indoors. You haven’t shopped in days and there’s no food in the house.
“It saves time and money to have food on hand. However, no matter how extensive your food-storage plan is, remember to eat what you store and store what you eat.”
(Jill Carman, consultant for the food advisory division of Agriculture Canada—ed.)
3 May 1981, Mobile (AL) Press Register, “Cooking is fun!” by Tommye Miller, pg. 13D, col. 1:
Her church teaches that you store what you eat, and you eat what you store, “going on the premise that if you’re in a crisis situation you wouldn’t have to change your eating habits radically.”

“Store what you eat, eat what you store”
But, I do store large quantities of items I don’t eat on a regular basis, in recognition that my post-SHTF diet will be laden with the standard rice and bean staples. As a result I have modified the simple “store what you eat, eat what you store” to this:
1) If what you eat is storable either in can goods lasting greater than one year, by all means store it and rotate it through your kitchen.
2) Purchase items you don’t normally eat that last longer than two years and have 30-60 days of supply in cans or other packages. Include good-tasting soups and grain-based breakfast food.
3) For items you would never eat unless the SHTF, purchase or package to store in excess of 20 years.
