i’m a lot less worried about nitrogen than i am of where the beef is sourced, and what they are injecting into the livestock - two things they have been increasingly secretive about. also, its pretty obvious there is some kind of short cut happening when you pay $9.99/lb for mystery-sourced beef at a chain supermarket vs $40/lb for local beef at a specialized butcher for the same cut. they use these same gasses in bags of chips and bread to displace oxygen.
