Question

What precaution is taken to protect against phenylketonuria?

a) Warning labels on products.
b) Banning phenylalanine-containing products.
c) Mandatory birth tests for all amino acids.
d) Developing a cure for phenylketonuria.

Answer 1

To protect against phenylketonuria (PKU), mandatory birth tests are conducted to detect the condition. If PKU is detected, a modified diet low in phenylalanine is initiated as early as possible. Foods high in phenylalanine, such as artificial sweeteners and certain animal products, must be carefully monitored to prevent symptoms and damage.

Step-by-step explanation:

To protect against phenylketonuria (PKU), several precautions are taken. One of these precautions is mandatory birth tests for all amino acids. Every infant in the United States and Canada is tested at birth to determine whether PKU is present. If PKU is detected, a modified diet low in phenylalanine is initiated as early as possible to minimize symptoms and damage. Phenylalanine is found in high concentrations in certain foods, such as artificial sweeteners and some animal products, so the intake of these foods must be carefully monitored.
