Food Allergies May Limit Growth
University of North Carolina researchers compared data on the weight and body mass index of 245 food-allergic children between the ages of 1 and 11 years old against data on other children of the same age range. Data were also compared between the children with allergies and children with cystic fibrosis or celiac disease, two conditions which are also known to inhibit growth.
It was discovered that after 2 years of age, children with any food allergy had lower weight and BMI than those without allergies, regardless of whether they had celiac disease or cystic fibrosis. Researchers also discovered that having a milk allergy in particular meant even less weight gain, as did having multiple food allergies.
“The impact of food allergies was particularly pronounced when it involves cow’s milk or when it requires the elimination of more than two foods,” Dr. Brian Vickery, the study’s lead author, told a news conference. “Milk allergic children aged less than 2 were particularly vulnerable to growth restriction, with weight and BMI significantly lower than in those children with other types of food allergies,” he said.
Vickery said physicians need to do nutritional assessment with children in either of the two groups, and consider whether supplements are required. He also recommended nutrition counseling for those dealing with children with milk allergy or multiple food allergies.
“We feel that health providers should counsel patients and caregivers about the growth-related risks of the elimination diets that are used to treat food allergy, and ensure that families are excluding only the foods that are medically required,” he said.
