Nutrition for phenylketonuria

Phenylketonuria, or PKN, is a congenital genetic inherited defect that causes unwanted accumulation of the amino acid phenylalanine in the blood. This is because the enzyme, which usually converts one amino acid( phenylalanine) to another( tyrosine), is missing or presented in insufficient quantities. As a result, phenylalanine accumulates in the blood and becomes toxic to the brain tissue.

. Newborns undergo a blood test using a blood test, so treatment can begin immediately, which means that it is possible to prevent the appearance of adverse side effects and conditions such as decreased intelligence, neurological complications, growth retardation, hyperactivity and convulsions. A dietician, a doctor, a geneticist and a psychologist who usually monitor the child's health at various stages of growth and development are usually involved in the treatment.

A strict diet with reduced intake of phenylalanine is the main treatment for phenylketonuria. Phenylalanine is found in most protein products, such as milk, eggs, cheese, nuts, soy beans, chicken, beef, pork, beans and fish. The infant is prescribed a special mixture for children of the first year of life, not containing phenylalanine. However, in limited quantities, it is permitted to use breast milk.

Creation of an individual nutrition plan for phenylketonuria

As a baby grows and becomes psychologically ready to eat solid foods, a nutritionist practicing in the treatment of PCF makes up an individual menu for him, which includes modified food sources of protein with a low content of phenylalanine and tyrosine. This ensures the intake of the necessary amount of calories, vitamins and minerals in order to maintain growth and development.

Because many products are contraindicated in phenylketonuria, the nutrition plan includes the intake of special supplements, which are often the main source of calories and nutrients. Products without phenylalanine, children and adolescents with PKN can consume without restrictions. The nutritionist creates an individual nutrition plan and changes it as necessary to ensure healthy growth and development.

Patients with phenylketonuria diet should be observed for life. A person with FKN needs to monitor blood to maintain the level of phenylalanine in her serum. In addition to blood monitoring, the nutritionist will regularly analyze the nutrition journal and the growth schedule, adjusting the patient's diet as needed.

Parents of children with FKN should be creative in preparing food and using special cooking books. The nutritionist should help them in planning not only food, but travel to rest and other special events. Try during the celebration of special events to focus attention around activities, and not around eating.

Team from an experienced nutritionist, doctor and psychologist will help you solve social problems at every stage of life. Knowledge is power, and the more parents, and eventually the child, will know about phenylketonuria, the faster the latter will start living a healthy, full life.
