"Grass-fed truly shines in the micronutrient profile for one reason. Grass-fed cows get more nutritious food. Remember: they aren’t munching on monoculture lawn cuttings (let alone soy and corn). They’re eating a wide variety of (often wild) grasses, sedges, rushes, shrubs, and herbs, each with its own nutrient profile. Of course, how nutritious those graminoids are depends on the quality of the soil, or the terroir. If we care about what our food eats, we should also care about what the food that our food eats is eating, right? Grass-fed isn’t just miraculously higher in selenium because of some magic process; it’s higher because grass grown in good wild soil patrolled by plenty of mobile, self-perpetuating organic fertilizer machines contains more selenium than soybeans or corn grown on nutrient deficient land. It should follow that pastured, grain-supplemented beef raised on good soil by good ranchers also contains higher levels of micronutrients when compared to the CAFO cow, albeit not as high as the purely grass-fed.

Eat beef, first and foremost. Get the highest quality beef you can afford, whether that ends up being premium grass-finished from the farm up the road or USDA Prime from Costco. Don’t let the perfect be the enemy of the good. Man cannot live on wild caught canned sardines and crushing angst alone."

Gotta love a man with a sense of humor

Dr Harris talks about eating ruminants when 100% pastured is not available/affordable.
