The reference files lists all sources of data.\u0026lt;/p\u0026gt;\n\n\u0026lt;p\u0026gt;Phenylalanine (Phe) is a key nutrient in the dietary management of the metabolic disease phenylketonuria (PKU). To give more freedom to PKU patients, we propose a numerical process to estimate the Phe content of a commercial food using the information printed on the label (Nutritional Fact Label and ordered ingredient list). The process is amenable to implementation as a smart phone/Web app and could be integrated into a personalized dietary management software. Our tests show that the results are very accurate (\u0026amp;plusmn;13 mg per serving) in the vast majority of foods considered. Our approach can be modified to handle any other amino acid for the management of other inborn errors of metabolism. A similar approach can also be used for improving the precision (i.e., increasing the quantization resolution) of the nutrients already listed (e.g., protein).\u0026lt;/p\u0026gt;\n\n\u0026lt;p\u0026gt;J.
