Breeding for leaner red meat is a phenomenon of the last few decades, compared with breeding for fattier red meat which has been going on among domesticated cattle and swine for the last 10,000 years. Relatively leaner and relatively less processed red meat are relatively better for you, and there are various data about how relatively healthier the relatively better red meats are. But there are also clear and unconflicted data that vegetarians have far better health outcomes than omnivores, and that pescetarians, like Steve Jobs, who eat seafood and plant-based foods but no other meat, have still significantly better health outcomes than vegetarians.
