Kayleigh, I looked up the information on PKU disease as I promised. Just haven't seen you since I looked it up. I remembered a lot after I read the stuff as they screen babies for this disorder now regularly and years back I had a client who was severely developmentally delayed before the test was around. Basically your diet is as follows: Fruits and veggies, fresher the better, all you want. Limited cereal and grain products. It didn't say what limited is but you can easily consult with a dietician. Avoid meat, fish, eggs, poultry, dairy, nuts, soy, legumes, pennut butterand nutrasweet. You can buy products that are specially formulated for you. The research that I read says that damage can continue happening all of one's life and they must follow the diet. you can e-mail : pkunews@workmail.com
