Phenylalanine is an essential amino acid and it is found in nearly all foods which contain protein: meat (of all kinds), dairy products, nuts, beans, tofu... the list goes on and on.
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.These foods cause high blood phe levels for people with PKU.owever, if these foods were the only foods a person consumed, his or her diet would be lacking protein, vitamins, and minerals. That is where the special formula comes in. A special phenylalanine-free formula, such as Phenyl-Free*, contains protein, vitamins, minerals and energy (calories) with no phenylalanine.
