nah--they just won't grind in as much fatty tissue to make the extra lean gb.
There's such a small segment of the buying public in this nation that gives a rat's butt about that heart healthy thing, that it will have so close to zero effect that ya might as well call it zero. 98 of 100 retail buyers look at $/lb when buying hamburger meat and nothing else.
But, it will probably be played up by someone somewhere as something more--just one more "let's throw it at the wall and see if it sticks" marketing ploy. (maybe they'll offer a free set of ginsu steak knives or a plush toy if ya buy 10lb or more..)
