Can roast duck and milk be eaten together?
Generally speaking, Peking duck and milk can be consumed together, but overconsumption should be avoided. Detailed analysis is as follows:

Peking duck is rich in protein, fat, and various trace elements, while milk contains abundant protein, calcium, and vitamins. There is no direct nutritional conflict between Peking duck and milk. Consuming them together can provide comprehensive nutrition for the body. If an individual has good digestion and does not suffer from lactose intolerance or allergies to components in either Peking duck or milk, then consuming them together is acceptable.
However, Peking duck itself has a high fat content and is relatively greasy, while milk also contains a certain amount of fat and protein. Eating excessive amounts of both together may burden the gastrointestinal tract, leading to indigestion, bloating, and abdominal pain. Therefore, it is recommended to consume moderate amounts of Peking duck and milk in daily life to avoid adverse bodily reactions caused by overconsumption.
In daily diets, attention should be paid to dietary diversity and moderate intake of various nutrients to ensure balanced nutrition for the body.
