Dried beans and knowing how to cook them are a whole lot cheaper than canned.

Life depends on having clean water. If you don't have clean water, you die. Cleaning water is not rocket science. It requires some basic equipment and training.

That's one of the things that lots of missionary groups do, in third world countries, is teach people to use local resources to clean their water and stop the babies from dying.
