You'll notice on grass-fed beef that the fat has a yellowish tint as opposed to the fat on grain-fed beef that has a white tint. The yellow tint on the grass-fed fat is a sign of high nutrient density (which also translates into more flavor). You don't need to shy away from fat on grass-fed beef. Eating the fat is not harmful and is actually good for you. Give it a try the next time you grill our grass-fed & grass-finished steaks!
