How do you know if you have phenylketonuria?
You will have had a blood test that would have diagnosed that shortly after your birth. If you want to test that, go eat a couple packs of Equal sweetener...if you get deathly ill, you probably have PKU.
Persons diagnosed with phenylketonuria must have a specialised diet to prevent further intake of proteins containing the amino acid "phenylanine hydroxylase". If this is not done, and there is no diagnosis, phenylketonuria can lead to severe consequences, one of which is albinism, and ultimately retardation. In other words: EARLY DIAGNOSIS IS IMPORTANT!
Aspartame is a sweetener that is made up of two amino acids, one of them is call phenylalanine. The digestive system of those who have the genetic disease, phenylketonuria cannot digest this amino acid. It wreaks havoc in their bodies; so it does not help but hurt. This is why there is a warning label on products with aspartame warning those with phenylketonuria that there is phenylalanine in the product.
