Conscientious omnivores of the Michael Pollan variety champion grass-fed beef. It is claimed to be better for the cattle themselves than grain-finishing, since they eat what their rumens are evolved to digest (grass and legumes) instead of what fattens them quickest. Plus, they get to graze open pasture instead of being confined to a feedlot for the final four to six months of their lives. Grass-fed enthusiasts also claim it’s better for people because grass-fed meat is leaner and has a higher proportion of omega-3 fats than grain-finished meat. Some even argue that it’s better for the environment, since you don’t have huge piles of feedlot manure to manage; the cattle deposit their manure on grass, as they naturally would, and it ultimately nourishes the soil.
