Animals raised in a natural environment and on their natural diet are likely be healthier, and in turn, be a source of higher quality meat. Based on this premise, choosing meat from pasture raised animals makes a lot of sense and is supported by research that has identified a number of ways in which this type of meat is superior. However, a recent study done by researchers from Texas A&M is being used to claim the opposite, that beef from grain fed cattle is healthier than beef from pasture fed cattle.
Although there are many great reasons to choose meat from pasture raised livestock, eating conventionally produced meat is not necessarily a guarantee for poor health. Someone who primarily eats whole foods, is active, and manages stress well will still be likely to enjoy good health despite the concerns associated with conventionally produced meat. However, to insinuate in a general sense that beef from grain fed cattle is healthier than that from pasture fed beef is quite a stretch in my opinion.
