Childhood food allergies are on the rise, but nowhere is this more evident than among black children. A new study from Johns Hopkins University reports that food allergies have almost doubled in that population.
The study looked at more than 450,000 children between 1988 and 2011. During those years, food allergies increased among black children at a rate of 2.1 percent every 10 years, while only growing at a rate of 1.2 percent each decade among Hispanics and 1 percent every 10 years among white children.
“Our research found a striking food allergy trend that needs to be further evaluated to discover the cause,” study author Corinne Keet, M.D., an assistant professor of pediatrics, said in a news release. “Although African Americans generally have higher levels of IgE—the antibody the immune system creates more of when one has an allergy—it is only recently that they have reported food allergy more frequently than white children.”
A separate study found that many allergists can predict whether a child will be more likely to outgrow a food allergy or if it will remain a lifelong problem.
