Thread: Phenylalanine in Soda

Id been wondering for a long time what it meant on diet sodas with the phenylketonurics: contains phenylalanine warning. So I looked it up, and as Im sure many of you already know, its an aminio acid. Naturally I was curious why it was a warning; which it turns out like, 1 in 10,000 babies is born with PKU(Phenylketonuria,a disease) which causes them to go nutzo.

an inherited disease that, if left untreated, results in retarded mental development in children, has been shown to be associated with the lack of activity of the enzyme that converts phenylalanine to tyrosine. This results in the buildup of phenylalanine in the blood, an event leading to several pathological consequences.

Now for non psyco-bound people, it has some good effects.

HOW TO TAKE IT For pain relief, the recommended dosage is 1,000 to 2,000 mg a day, although for severe pain, it may initially be necessary to take up to 4,500 mg. Reduce or discontinue supplementation once the pain subsides. If you are depressed, it is important to get professional help. Michael Hirt, M.D., director of the Center for Integrative Medicine in Tarzana, Calif., prescribes 1,500 mg phenylalanine a day to patients complaining of depression and fatigue.

For best results it should be taken on an empty stomach. It can take one to two weeks to get the desired result. Do not take for more than three weeks at a time, as it may interfere with the body's amino-acid balance. Long-term supplementation of phenylalanine and other amino acids can also cause liver and kidney damage.

Well, heres my question.. long term supplimentation = what? Ive never found a drink which lists the amount of phenylalanine in it, they only say they have it.. So Im curious if diet soda(non coke/pepsi, Ive become a generic brand lemon lime fan, It actually tastes like something, and doesnt contain the phosphoric acid ) contain enough to cause problems down the road.

poultry contains phenylalanine...I wouldn't worry about it since it is a naturally occurring amino acid...
