longer-term supply

"For longer-term needs, and where permitted, gradually build a supply of food that will last a long time and that you can use to stay alive, such as wheat, white rice, and beans. These items can last 30 years or more when properly packaged and stored in a cool, dry place. A portion of these items may be rotated in your three-month supply."

This is the "new" category that I think is most closely related to the traditional food storage. They've tweaked it, though, to be much more simple to understand. These products are intended to help us "stay alive." The church has recommended *Wheat, white rice, corn and other grains [25 lbs per person per month] and *Dry Beans [5 lbs per person per month]. All of the recommended products have shelf lives of 30 years or more.

If you add nine-months of these long term storage items to 3-months of short term storage, then you get your traditional one year of food storage. Below, I've calculated 9-months worth based on amounts found on the Provident Living website:
*Store 225 lbs of grains per person.
*Store 45 lbs of dry beans per person.
I would say that this is a good minimum goal for a family.
