What to do about children's picky eating and lack of activity?

Patient's question:

Age
Detailed medical history and consultation purpose: My daughter is not very active and has poor appetite.
Auxiliary tests: Recent tests indicated anemia.
Current general condition: Height 120 cm, weight 21 kg, hair is relatively yellow, and she loves to dream at night.
Other: None

Doctor's answer:

It may be caused by zinc deficiency-induced anorexia. I suggest taking your child to a regular hospital for a comprehensive examination to identify the cause and receive targeted treatment. While undergoing treatment, it is recommended to take Gaojixing tablets or Kaibel Zinc Selenium Treasure, which efficiently supplement zinc, selenium, and other trace elements without hormones or any toxic side effects.
Additionally, zinc supplementation can be achieved by consuming foods rich in zinc, such as meat (beef, pork, liver), seafood (oysters, etc.), poultry, egg yolks, peanuts, etc. Zinc is found in fish, eggs, meat, poultry, whole grains, wheat germ, cheese, nuts, beans, and yeast. The bioavailability of zinc is higher in animal-based foods.
