What are the dietary taboos for children with hydrocephalus?

Patient's question:

The child has recently been crying and vomiting frequently, and is reluctant to take naps in the evening. A thorough examination at the hospital revealed that he suffers from hydrocephalus in infancy. The doctor performed surgery to drain a small portion of the accumulated fluid in his brain. The child is currently undergoing treatment at the hospital, and I would like to know what dietary restrictions apply to his condition. I want to prepare some nutritious and delicious food for him to aid in digestion.
I hope to receive help: What are the dietary restrictions for children with hydrocephalus?

Doctor's answer:

Protein Digestion
Protein is one of the main components of brain cells, accounting for 30% to 35% of the weight of the brainstem. It serves as the primary material basis for the activation and inhibition processes of brain cells and plays a crucial role in various aspects such as memory, language, thinking, activity, and neural transmission. The growth, development, and nutrition of the brain are closely related to the adequate supply of protein.
Foods rich in protein include: eggs, wild pork, wild rabbit meat, wild ducks, wild chickens, quail, sparrows, etc.; non-farmed fish and shellfish such as oysters, octopus, squid, shrimp, etc.; beef, pork, chicken, and other meats; as well as soybeans and soy products, peanuts, red beans, fava beans, sesame seeds, and walnut kernels, among other dry fruits.
