The ribeye steak is beef steak cut from a ribeye roast of a steer. Among the better cuts, a ribeye steak has little connective tissue and a relatively high level of fat marbling which make the meat tender and flavorful. A good source of nutrition, the ribeye steak provides high levels of protein, vitamins and minerals. However, the meat is also high in both saturated fat and cholesterol and should be eaten in moderation.
