Canada

Bagged dry beans require more prep before they can be eaten, though, and you have to have the clean water to rehydrate them on site, and the know-how to do it. There's an energy cost (electricity in remote off-grid communities isn't necessarily cheap either), and a time cost on the part of the people cooking, all of which has to be taken into consideration. That doesn't mean that replacing canned foodstuffs with dried or freeze-dried can't be part of the answer, but it may have to be supplemented with recipes or facilities or cooking classes or something.

If there's a systemic issue here that goes beyond people in the supply chain profiteering, the solution may not be simple.
