Phenylalanine and Tyrosine

[john]

Whey protein contains a bunch of amino-acids - This info seems to contradict the benefits of whey protien I have read elsewhere

Very confusing

Phenylalanine can promote the cell division of existing malignant melanoma cells. If you have melanoma, or any other form of cancer for that matter, avoid phenylalanine. According to a study in the Journal of Human Nutrition and Dietetics, three patients with metastatic melanoma and three with metastatic breast cancer took part in a study that involved a diet of phenylalanine and tyrosine administered at a very low dose (10 mg/kg/day for 1 month). The results were not good. Researchers reported that all the patients experienced anxiety and depression and other side effects. They also lost weight. The authors of this pilot study concluded: "Low phenylalanine and tyrosine diets do not appear to be a viable treatment option for patients with advanced cancer" (Harvie et al. 2002).
