Beef is the culinary name for meat from cattle, particularly skeletal muscle. Humans have been eating beef since prehistoric times. Beef is a source of high-quality protein and nutrients. Beef is the third most widely consumed meat in the world, accounting for about 25% of meat production worldwide. Cattle raised for beef may be allowed to roam free on grasslands, or may be confined in pens as part of a large feeding operation where they are usually fed proteins, roughage and vitamins/minerals.
