Before buying and eating, please check with the hospital where you used to see whether it is edible. Among many rare diseases, patients with congenital metabolic abnormalities are a relatively large group. Patients can control their diet strictly and take special milk powder to take care of their growth and nutrition. Healthy growth can be achieved only if the demand and ingredients are restricted. This group of patients with amino acid/organic acid metabolism abnormalities who need strict diet control, in addition to using special milk powder, the sooner they are exposed to low-protein foods, the better their adaptability. This association organizes the "low-protein recipes" in nutrition classroom activities in recent years. Hope to provide a variety of choices for the family members who are racking their brains. The ingredients used in the recipes are mostly readily available in the market, and occasionally special ingredients such as low-protein rice and noodles are added to add variety. Recipes are not static, and can be developed and adjusted according to personal preferences and food intake, but remind you that if the supply description or ingredients are different from the recipe, you must recalculate the nutritional content. Patients who require a low-protein diet are usually patients with inborn errors of metabolism, such as phenylketonuria, abnormal leucine metabolism, and maple syrup urine disease.
