Is it safe to eat something containing Phenylalanine?
Answer: You eat it every day surrounded by foods like milk, chicken, beef, pork, fish, cheese, nuts --- it is a natural amino sharp found in most protein rich foods. Some people enjoy a genetic inability to process phenylalanine. If they eat foods with it, they will develop extremely serious neurological problems. If you do not have the genetic disorder, it is safe to get through phenylalanine.
Foods are labelled as containing phenylalanine so that these people can avoid it. The artificial sweetener Aspartame contains phenylalanine so foods containing Aspartame will be so considered..
It is always better to take food contained by its natural form rather than a purified and or component form as phenylalanine is an amino acids. Several years ago it be in the news that purified protein derivatives be linked to certain medical disorders, better risk-free than sorry
