Anybody manage to find mussels or oysters tinned in an oil that isn't PUFA? All I can find is crap like sunflower and cottonseed.
Fresh from your local fishmonger? I can see other problems than pufa, such as source of the food and cooking methods. It's not surprising you can hardly find them canned. It would cost a huge lot for a canned product, definitely not something that a grocery shopper would pay for. Its more like something you'd get at a restaurant for the sea taste, and canning defeats this purpose.
