You go to buy some beef and are confronted by rows of meat cuts with adjectives — hormone-free, grass-fed, organic, grain-fed, extra-lean, etc. When it comes to grain-fed versus grass-fed beef, are there any key differences in the nutritional qualities of the meat? Do any of the differences greatly matter? First worth highlighting is that both grain-finished and grass-fed beef are highly concentrated sources of beneficial nutrients. Each type of beef is loaded with vitamins B12, B3, and B6; highly bioavailable iron, selenium, and zinc. Each type of beef also contains high quality protein and various lesser-known nutrients, such as creatine and carnosine important for muscle and brain functioning.
