Even in older continuity there was a long length of time where Wolverine required a lot of protien in his diet to maintain his healing factor. The explination was better than most. The healing factor used a form of excelerated metabolism and required the protein to work. We have come leaps and bounde from that era of the Clawed Canuck. For the record, I too am in favor of round/teardrop claws.
