the reason bison is considered better than beef is they are obviously pastured raised.
a lot of farmers though are doing the same with beef now and that market is doing well. i get my beef from whole foods and it is step 4 quality pasture and grassfed organic. you go to walmart and get beef and it is tortured cows who stand in their own shit eating slop all day. you be the judge which one is better
the superior quality means more vitamins and minerals, plus the animals are treated well before slaughter.. both important for me
