What does the LDS church have to do with meal storage?
A lot. Their church urges their members to have at least 10 years' worth of food stored up for emergencies. This may be because they are so committed to helping their needy—it limits the number of needy people that they will have to help in a crisis.
A lot of the big-name long-term-storage-food suppliers are located in Utah and run by Mormons.
The Mormon Church also has their own bulk canneries where members (and non-members) can go fill up #10 cans with dehydrated foods and have them sealed for long-term storage—at a pretty reasonable price. It isn't the highest quality, or the most varied, items you can get from other companies, but it is affordable and capable of keeping someone alive in times of shortage.
