Right.. but i remember the tv news did mentioned that it is safe for MOST people but not for those who are sensitive to this Phenylalanine and cant consume them at all.
Breast milk from mammals is rich in phenylalanine. It is also produced by plants and most microorganisms from prephenate, an intermediate on the shikimate pathway. this is very interesting.
Phenylalanine is found naturally in foods such as eggs, milk, bananas, and meat. If you are PKU (Phenylketonuric) or sensitive to phenylalanine, you will react to the phenylalanine in aspartame. You many want to get a blood test to check for this condition. Over the past 20 years, humans have become more aware of PKU reactions because human beings began using isolated phenylalanine to the degree it is harmful to some individuals, many as aspartame side effects. My suggestion would be to research PKU and phenylalanine extensively. Phenylalanine can be very harmful to diabetics.

[edit] Phenylketonuria
Main article: Phenylketonuria
The genetic disorder phenylketonuria (PKU) is the inability to metabolize phenylalanine. Individuals with this disorder are known as "phenylketonurics" and must abstain from consumption of phenylalanine. This dietary restriction also applies to pregnant women with hyperphenylalanine (high levels of phenylalanine in blood) because they do not properly metabolize the amino acid phenylalanine. Persons suffering from PKU must monitor their intake of protein to control the buildup of phenylalanine as their bodies convert protein into its component amino acids.
A non food source of phenylalanine is the artificial sweetener aspartame. This compound, sold under the trade names "Equal" and "NutraSweet", is metabolized by the body into several chemical byproducts including phenylalanine. The breakdown problems phenylketonurics have with protein and the attendant build up of phenylalanine in the body also occurs with the ingestion of aspartame, although to a lesser degree. Accordingly, all products in the U.S. and Canada that contain aspartame must be labeled: "Phenylketonurics: Contains phenylalanine." In the UK, foods containing aspartame must carry ingredients panels that refer to the presence of 'aspartame or E951',[3] and they must be labeled with a warning "Contains a source of phenylalanine". These warnings are specifically placed to aid individuals who suffer from PKU so that they can avoid such foods.
Geneticists have recently sequenced the genome of macaques. Their investigations have found "some instances where the normal form of the macaque protein looks like the diseased human protein" including markers for PKU.[4]

Phenylalanine in diet soda: Is it harmful?
My favorite diet soda lists phenylalanine as one of its ingredients. I thought I read somewhere that phenylalanine is bad for your health. Can you clarify?

Answer
Phenylalanine is an essential amino acid, which means you need it in your diet. Amino acids are the building blocks of protein. Phenylalanine is especially important to young, growing children. Adults need less phenylalanine in their diet.
Phenylalanine is found in protein-rich foods, such as milk, cheese, nuts, seeds, poultry, fish, as well as some leafy vegetables and whole grains. It's also found in diet foods, such as diet soda, that contain aspartame.
Phenylalanine is safe to eat or drink unless you have phenylketonuria (PKU), a rare birth defect in which an enzyme needed to process phenylalanine is missing. PKU is usually diagnosed in infancy.
For infants and children with this disorder, consuming phenylalanine is dangerous. Adults with this disorder should consult their doctors regarding whether phenylalanine is a concern. If you do not have PKU, phenylalanine in foods is not a concern.

thats all we have to be concerned for those WHO are sensitive to it and cant consume that.
