Beef is indeed a good source of quality in protein. Those foreigners really like steak and beef. They won't eat other meat, because they think other meat is particularly cheap, and they won't eat some bones or other parts of meat. When they eat cattle, they mainly eat the meat on their bellies. So they are very wasteful.
And what is used to produce a cow is much more wasteful than raising pigs. Raising a cow will produce a lot of carbon emissions than raising a pig. Therefore, it is untenable for foreigners to accuse us of eating too much meat and causing an increase in carbon emissions. Their beef is the chief culprit in increasing carbon emissions. There is too much beef in their diet. We have many other ingredients. Their main ingredients are steak and hamburgers.
However, beef is really healthy. Those foreigners are strong because they eat beef, a high-protein food. Beef can also replenish physical strength. If you are physically exhausted, eating some beef can make you recover quickly. But beef is much more expensive than pork, because raising a cow is very troublesome and requires a lot of investment, so its cost is particularly high and it must be sold at a higher price. You can buy beef according to your own situation.
