Is Your Kid Truly Allergic? Tests Add to Food Confusion By MELINDA BECK


Grayson Grebe started getting eczema on his cheeks when he was just 4-weeks-old. At 6 months, he was diagnosed with allergies to wheat, dairy, eggs, nuts, oats, rice, barley, chicken, pork, corn and beans; his mother, who was breast-feeding him, had to stop eating them all. At 10 months, doctors cut out 20 more foods, including all fruits and vegetables, and put Grayson on a hypoallergenic formula. Even so, his eczema was so bad that his parents put him in mittens, long-sleeved shirts and long pants so no skin was exposed. "Otherwise, he'd scratch himself until he would bleed," says his mother, Amy Grebe of Albuquerque, N.M.

At wit's end, the Grebes took Grayson to National Jewish Health, a hospital in Denver that specializes in allergies and respiratory diseases. Doctors there suspected that his food allergies might not be causing the eczema—and that some might not be food allergies at all. After carefully supervised "food challenges"—giving him tiny amounts and monitoring him closely for signs of a reaction—a number of foods went back in his diet. "We came home with 12 foods he could eat," says Amy Grebe. "It's made so much difference in our lives."

For parents of children with food allergies, this may be both welcome and unsettling news: Many kids whose allergies were diagnosed on the basis of blood or skin tests alone may not be truly allergic to those foods, experts say.

HIGHLY recommended reading for anyone that has a diagnosis without clear reaction history to the particular food in question.  Strongly recommended reading for everyone, in fact.
