Saw this on Mountain House's Facebook page - we all know their #10 cans last for 25-30 years. Now, it turns out their pouches also have a long lifespan. Before, it was thought these only lasted 7+ years. Loses some quality (and probably some nutritional value) but still edible. I'd still choose #10 cans for long-term storage, but knowing that pouches also have a long lifespan creates some new options for food storage.
