Which off the shelf foods last the longest?

[NorthernRaider]

Ok guys I get the message this is at least the fourth thread i have started trying to deal with specific issues and each time it get derailed or redirected onto other issues, if I try talking about compounds you guy go on about anything but compounds, if I talk about specific groceries you guys go onto canning issue, american lists and anything but the subject matter.
I admit defeat and give up, its your forum you lot can start the threads I'm fed up trying to make progress.
