It is not recommended that you eat more, otherwise it will lead to abdominal pain and abdominal cramps, which will affect the health of pregnant mothers and the development of the fetus. In addition, because there are many blood vessels and nerves in the duck's head, the most concise accumulation of toxins, such as pesticides and fertilizers in humiliating waters or plants and chemicals added in feed, can come into the animal's body with ingestion. At the same time, the places where food is processed and sold do not meet the requirements of the food hygiene law, which will bring potential safety hazards. Therefore, when buying duck head and fish head, you should go to a market that is formal and supervised, and care whether you work in a formal breeding and processing place, and don't buy it on the street.
