The assistance of a metabolic dietitian is needed to educate individuals about appropriate adjustments of phe diet as well as ensuring adequate energy and micronutrient status with the potential for decreased consumption of AA formula.

Management of phenylketonuria and hyperphenylalaninemia: the French guidelines in French Arch Pediatr.
Vegetables and fruit are allowed in measured amounts only! In order to promote protein synthesis and provide variety within a very restrictive diet, it is best to allow the maximum amount of natural dietary protein from breast milk or infant formula in infancy, and later in life from fruits, vegetables and low protein products. Thus, new dietary options are clearly needed to improve the acceptability of the low-phe diet to achieve lifelong metabolic control of PKU. Moreover, ongoing nutritional assessment over the life cycle is essential for optimal metabolic control of PKU and to insure optimal growth. Both high tyrosine enrichment of protein substitutes and extra free tyrosine supplementation may not be as safe as considered at present, especially to the fetus of a woman with PKU. Reassessment of phenylalanine tolerance in adults with phenylketonuria is needed as body mass changes. Influence of phenylalanine intake on phenylketonuria. Substances Phenylalanine. Retardation can be prevented if phenylketonuria is diagnosed in the first three weeks of infancy and dietary treatment started straightaway.
Think that phe what is diet thr restrsted really All above
The diet for PKU consists of a phenylalanine-free medical formula and carefully measured amounts of fruits, vegetables, bread, pasta, and cereals. Many people who follow a low phenylalanine phe food pattern eat special low protein breads and pastas. They are nearly free of phe, allow greater freedom in food choices, and provide energy and variety in the food pattern. Foods that contain large amounts of phe must be eliminated from a low phe diet. These foods are high protein foods, such as milk, dairy products, meat, fish, chicken, eggs, beans, and nuts.
