Yes, beef is generally better for you than pork because cows and other ruminant animals do a better job at converting what they eat into healthy fats. Pigs and other monogastric animals are often fed a corn and soy-based diet that increases the omega-6 concentration in their fat tissue. Additionally, stored feed is often contaminated with mold, such as Ochratoxin A (a “storage fungi”) that ends up in the meat you consume. If you like pork, I recommend sticking with pasture-raised options only.
