text: A 1987 study found that consumption of dietary phenylalanine in the usual way, as a constituent of protein, does not elevate brain phenylalanine levels because the protein elevates plasma levels of the other large neutral amino acids (LNAA)
text: The debate centers on whether a significant spike in blood plasma phenylalanine occurs at typical aspartame ingestion levels, whether a sudden influx of phenylalanine into the bloodstream adversely effects uptake of other amino acids into the brain and the production of neurotransmitters (since phenylalanine competes with other Large Neutral Amino Acids (LNAAs) for entry into the brain at the blood brain barrier), and whether a significant rise in phenylalanine levels would be concentrated in the brain of fetuses and be potentially neurotoxic.
