Phenylketonuria (PKU) - Video

If you have Phenylketonuria (PKU) (Imbecillitas phenylpyruvica, as it was formerly known), you MUST avoid Aspartame (NutraSweet). Persons with the genetic disorder phenylketonuria (PKU) cannot metabolize phenylalanine. This leads to dangerously high levels of phenylalanine in the brain (sometimes lethal). It has been shown that ingesting aspartame, especially along with carbohydrates, can lead to excess levels of phenylalanine in the brain even in persons who do not have PKU. Aspartame is 40% phenylalanine.
