I've heard this too, actually. I haven't tried it yet though. I've actually been terrible at the dry bean angle, opting for canned way too often out of sheer laziness.

Canned beans seems cheap until you buy a pound of dry for about a dollar. Canned food is essentially salt and water with a bit of overcooked vegetable.

I don't actually care about cost for this, opting for convenience. I often store ingredients at work so I have no excuse to go out.

Anyway, several of our Canadian brands are ultra low sodium, that this is a nonissue.

There is the issue of BHA in can linings: http://www.consumerreports.org/cro/magazine-archive/december...

canned beans are also... calm.

If you rinse them.
