The following quotes are taken from the book Follow Me (Relief society personal study guide 4)
For more than fifty years, the church has told members that they need to be able to sustain themselves with a year's supply of food in times of emergency. " Recent surveys of church memebers have shown a serious erosion in the number of families who have a years supply of lifes necessitites. Most members plan to do it. Too few have begun" (Thomas S. Monson.)
In many circumstances, having a year's supply of these commodities is not possible because of limited budget or space. However, a smaller supply of a few essentials is possible in most situations. It is wiser to have food for only a few days, weeks, or months than to have no storage at all.... Our food storage should be adapted to meet our individual needs.
"The key to successfully storing food is to remember that it shouldn't be a one-time expensive purchase, but it must be many small purchases forming a regular habit, much like daily prayer and scripture study, ect. We supplement our basic storage by setting aside a small amout of money in our house hold budget for regularly purchasing a pre-planned variety of food items"
President Ezra Taft Benson said: " You do not need to go into debt...to obtain a year's supply. Plan to build up your food supply just as you would a savings account. Save a little for storage each pay-check"
Food can be stored in limited space. Some member use space under beds and stairways and in closets and corners. Stacked containers can be covered with cloths to make nightstands and accent tables. Containers can be stored underneath window draperies, behind sofas, and even in space made available by other family members and friends.
Store canned goods in the coolest, darkest, and driest place possible.
