2. Many people like to eat mutton rolls and fat beef rolls, mainly because they taste better. However, the two foods are similar, except that the fiber of beef is bigger and more chewy than mutton. Beef is generally large and loose, and mutton is generally small, but elastic, not as loose as beef. The flavor of mutton rolls will be stronger than that of fat beef rolls, but there are still many additives in mutton rolls and fat beef rolls on the market, which are not completely healthy ingredients. Mutton is high in protein and low in fat. Its protein content is lower than beef, higher than pork, its fat content is higher than beef but not higher than pork, and its carcass fat layer is thin. Beef is an excellent high-protein food, and its nutrients are easily absorbed by human body.
