What happens when people that have phenylketonuria consume aspartame?

When individuals with phenylketonuria (PKU) consume Aspartame, they are at risk because aspartame contains phenylalanine, an amino acid that people with PKU cannot metabolize properly. This can lead to a dangerous buildup of phenylalanine in the blood, which can cause serious neurological issues and cognitive impairments. As a result, individuals with PKU must strictly avoid aspartame and other sources of phenylalanine to maintain their health. Regular monitoring of dietary intake is essential for managing their condition.
