Can beef and mutton be eaten together?
Generally speaking, beef and mutton can be consumed together, but the principle of moderation should be followed. Detailed explanation is as follows:

Beef and mutton are rich in high-quality protein and contain abundant iron and B-complex vitamins. Consuming moderate amounts of beef and mutton together in meals can provide substantial nutrition and will not produce harmful substances or cause adverse effects on the body.
However, if beef and mutton are undercooked or improperly handled, they may carry bacteria or parasites, which could lead to food poisoning. For individuals with gastrointestinal diseases, sensitive digestive systems, or a history of food allergies, consuming beef and mutton together may increase the burden on the digestive tract and cause indigestion, bloating, or other symptoms.
In daily cooking, it is important to ensure that meats are thoroughly cooked to kill any potential pathogens. Maintaining good eating habits, such as chewing food slowly and thoroughly, can aid digestion and nutrient absorption. Additionally, excessive consumption of beef and mutton at one time should be avoided to prevent digestive system issues.
