Living With Food Allergies

Breakthroughs in research have the potential to radically alter life for children who can't eat certain foods. Until then, this is what doctors and fellow parents want you to understand.

When Lissa Roberts's daughter Reagan was only a few weeks old, she developed fire-engine-red eczema from head to toe -- and no one could figure out why. At her pediatrician's suggestion, Roberts eliminated cow's milk from her own diet, then stopped breastfeeding and tried several different formulas. Nothing worked. Finally, when Reagan was 15 months old, tests revealed that she had a life-threatening allergy to cow's milk, eggs, and peanuts. Since then, milk has been the hardest to avoid. "There's some form of milk in so many foods," Roberts explains. "If someone who had milk on her hands so much as touched Reagan's cheek, she'd break out in hives." One sip would leave her vomiting and gasping for breath. "Every parent worries about her child's health," says Roberts, a mother of two in Ellicott City, Maryland. "But when you have a highly allergic child, it's a whole different level. You're scared to let your child out of your sight."

Like other kids with severe food allergies, Reagan would sit, often by herself, at the milk-free table during school lunch and snacktime. She'd tote her own cupcakes to parties, and restaurants were off-limits. "Some have allergy menus, but the possibility of cross-contamination (like someone accidentally using the same spatula to make an egg dish and an egg-free dish) was too risky," says Roberts.

That was then. Today, Reagan, now 11, can have all the milk and ice cream she wants. The best day of her life? When she could finally eat pizza -- with real mozzarella cheese -- thanks to a revolutionary treatment for food allergies being developed at Johns Hopkins Childrens' Center, in Baltimore, by Robert A. Wood, M.D., chief of pediatric allergy and immunology. (A few other medical centers in the U.S. are also using the therapy.) Still in clinical trials, this so-called oral immunotherapy involves slowly desensitizing the immune system of highly allergic children by feeding them gradually increasing amounts of whatever they're allergic to, such as milk, peanut, or egg proteins, and slowly boosting their ability to tolerate the foods.

Each week for a year, Roberts took her daughter to Dr. Wood's office. There, under close supervision, Reagan was given slowly increasing amounts of milk protein mixed with a chocolate or strawberry drink. She also got another premixed dose every evening, upping the amount in carefully calibrated increments. From time to time, the doctor checked her blood levels for antibodies to milk; if they dropped, that was a good sign. "We were both excited and terrified," says Roberts. "It's scary to watch your child eat something that for years you knew could end her life."

Though shots for seasonal allergies (also known as immunotherapy) are standard practice, the approach has proven risky for food allergies because reactions to the shots were too severe to justify continuing experiments. That's why the success of the oral approach is such big news. "It has the potential to change, and save, children's lives," says Dr. Wood. The treatment is at least ten years away from widespread use -- and not something to be tried at home -- but food-allergy experts haven't been this excited in a long time.

Five years ago, there wasn't a lot of research on preventing or treating food allergies. Thanks to groups such as the Food Allergy Initiative, which aims to find a cure by funding major studies, researchers know more than ever. "We never thought we'd get this far," says Wesley Burks, M.D., chief of pediatric allergy and immunology at Duke University Medical Center, in Durham, North Carolina, who's overseeing immunotherapy trials. "Will we find a cure? We're cautiously optimistic."

One recent breakthrough comes from Parents advisor Hugh Sampson, M.D., director of the Jaffe Food Allergy Institute at Mount Sinai School of Medicine, in New York City, who led a study suggesting that between 75 and 80 percent of children with a milk allergy can tolerate foods containing milk proteins if they're baked and therefore extensively heated. What's more, when kids eat these items they also develop a tolerance to all milk products. Dr. Sampson is now conducting another study to confirm this. If the finding turns out to be true, "it will change the current paradigm for treating milk-allergic children," he says.

But the urgency for research has been driven by unsettling statistics. One study found that nearly 8 percent of children under age 18 have food allergies. Another reported an 18 percent jump in food allergies in kids of the same age over a period of a single decade. Doctors aren't sure what accounts for the spike in cases, though everything from environmental pollutants to society's obsession with hygiene has been blamed. With the help of experts from The Food Allergy & Anaphylaxis Network (FAAN), a 25,000-plus-member Fairfax, Virginia, nonprofit that provides awareness, advocacy, and education and advances research, we've gathered the latest thinking on a complicated, highly charged subject that, one way or another, now affects all parents.
