No bread, no dairy, no meat: Living with PKU means eating lots of vegetables, fruits
Ezekiel Sanford was 2 days old when his Binghamton pediatrician told his parents: “You have to take him to Upstate.”
A routine blood test showed that Ezekiel had a rare inherited disorder called phenylketonuria, or PKU, which affects one in 15,000 newborns. The pediatric geneticist and medical specialists he needed were a short drive away, in Syracuse.
At the Upstate Golisano Children‘s Hospital, Ezekiel is seen by pediatric geneticist Joan Pellegrino, MD, and her team, which includes a dietitian, nurse practitioner, genetic counselor, social worker and nurse. His first year, Ezekiel had many appointments and lots of blood work done at the children‘s hospital.
One of their first tasks was to help Ezekiel‘s mother, Melissa Sanford, figure out how to breast-feed her son safely. It required alternating breast milk with a special formula for infants with PKU, counting the minutes he nursed and measuring the ounces of formula he drank. The family has become accustomed to this level of watchfulness.
For the rest of his life, Ezekiel will need to follow a strict diet that limits his intake of phenylalanine, an amino acid found in most foods, particularly those that contain protein.
Ezekiel‘s diet includes no bread, no dairy and no meat. He eats fruits and vegetables and gets one-third of his calories from a formula that contains a synthetic protein that lacks phenylalanine. Everything he eats has to be weighed in grams and calculated for its phenylalanine content. Fortunately, Ezekiel loves fruits and vegetables and is happy to remind anyone who‘s listening that “cooked carrots are yum, yum, yum.”
“Ezekiel is receptive to his diet, and we are vigilant,” explains his father, George Sanford.
With guidance from the Upstate team and their own research, Ezekiel‘s parents have found conferences, support groups and medical food companies, all of which help Ezekiel lead a healthy, normal life. His parents read food labels carefully, contact manufacturers and order products from medical food companies. As a result, Ezekiel is able to enjoy pizza and garlic bread, as long as it‘s made with a special flour designed for people with PKU.
Today, Ezekiel is 5, and he‘s used to the biweekly, at-home blood tests that will always be part of his life. He sees his Upstate team twice a year and started kindergarten this fall.
Ezekiel, his parents and three siblings are looking forward to moving to a farm — where they plan to grow lots of fruits and vegetables.
Testing for PKU
All babies in the United States, plus many other countries, are routinely screened for metabolic disorders, including phenylketonuria, or PKU, at least 24 hours after birth. A few drops of blood are collected from the heel or the bend in the arm.
In PKU, the body is unable to break down the amino acid phenylalanine. If it builds to harmful levels in the body, phenylalanine can cause intellectual disability, neurological disorders and other serious health problems.
People with PKU must limit their intake of dietary protein and may take a nutritional supplement that provides adequate protein without phenylalanine.
