So I know that organic grassfed beef is supposed to be the healthiest form of beef you can eat and I've seen a number of folks that have noticed good things after switching to grassfed beef. Conventional grain fed beef (including organic, but not grassfed) has way lower nutritional value in the form of good fats, etc. I've basically been trying to buy mostly grass fed beef these days. However, I'm wondering about other meats now, like pork and chicken. I haven't actually found such thing as "grassfed" chicken or pork. I've seen organic chicken, free range chicken, and humanely raised pork. These terms seem a bit more ambiguous. Like an organic chicken may just be fed grains that are organic and not be as healthy as a chicken fed a natural diet (I'm not even really sure what chickens eat naturally). So, for those of you that are into the grassfed beef thing (or naturally raised meat in general), how do you select your other meats like chicken or pork where it's not as clear as with grassfed/grainfed beef?
