We try to eat pasture raised beef products as much as possible. We order from a local farm. Pasture raised animals are typically leaner and they have a better balance of EFAs then the grain fed stuff you buy at the supermarket.
It is a healthier choice, by far.

I love our farm. If you're in Iowa, I can send you the link to that one!
Our guy also delivers fish from Alaska (he has a business partner there, and they do their own fishing and stocking.) Since this has been going well, he is also going to add chickens, so I will be set!

The Gardenofeatindiet.com book discusses in detail why it's better to eat pasture raised meats.
