"Build a small supply of food that is part of your normal, daily diet. One way
to do this is to purchase a few extra items each week to build a one-week supply
of food. Then you can gradually increase your supply until it is sufficient for
three months. These items should be rotated regularly to avoid spoilage."
I have the great fortune to have several siblings who share my interest in preparedness. The LRH's sister has prepared the following documents to assist in gathering the needed items for your 3-month supply. (My thanks to Teri M. in Tennessee for these forms)
Use this document to track or plan your menu for 2 weeks.
After you have completed this step, enter your list of ingredients into the following form. It will automatically calculate your totals for you. LRH's sister states that she prints out a current list each time she goes shopping so that she can consistently knows what she needs to purchase to have her 3 month supply on hand. You can also use the form to determine how much you would need to purchase if you wished to have more storage ingredients on hand.
