If they are dry, they're fine. That's dehydrated in a nearly gas tight package, same tech as the Mountain house stuff.

I'm talking about the Zataran's wet pack pouches. And I think the reason why the salt is so high is that they are using a budget version of MRE tech. MREs really aren't that expensive, the packaging is. So, to cut corners, they use a cheaper package and use an all natural preservative that doesn't look so scary on the ingredients list. IE, salt.
