When kids have food allergies , the tiddler ’s parents may think they have food allergies too , but this is often not the case , a unexampled study come up .
The study , which involve only parent of kids withfood allergies , showed that many parents who reported also having food for thought allergies did n’t actually have any . In fact , when the researchers conducted allergic reaction tests on parent who thought they had these allergy , more than 70 per centum of these parents tested negative .
The written report call into question the reliability of people ’s self - reports of allergy , the researchers said . The finding are also surprising , given that parents whose children have solid food allergies might be expected to have more knowledge than people in general about what look as a intellectual nourishment allergic reaction , the investigator said .
What ’s more , the effect intimate that a unwashed practice may be a problem : Doctors often ask parents if they have food for thought allergic reaction as a way to fix whether their children will be at high peril for produce allergies , the researchers said . " Our study suggests that using paternal report of food allergic reaction as a risk factor is unreliable , " the researcher wrote in the Oct. 12 issue of the journal Annals of Allergy , Asthma and Immunology .

The study involve nearly 2,500 parents ofchildren with food allergieswho lived in Chicago . The parent filled out a survey in which they answer question about substances they were allergic to , and also undergo allergic reaction testing . The researchers used two type of allergic reaction test : A skin - prick test , in which an extract of a substance is placed on the cutis and the peel is pricked to see if there ’s an allergic reaction , and a blood run , in which investigator try out the line for antibodies to specific substances . The investigator tested for food for thought allergies as well as other vulgar allergies , such as those to computed axial tomography and dog .
most 14 percent of parent order they had food allergies . But of these , just 28 pct in reality try incontrovertible for an allergic reaction to the food they reported , the survey found . Among parent who reported allergies to straw , fish , testicle or milk , less than 20 percent actually tested positive for such an allergy . Among parent who report peanut allergy , about 56 percent were actually allergic to that food .
It ’s potential that hold children with food allergies top some parents to think they had a food allergy too , because they were more cognizant of food allergy problems , the investigator said . It ’s also possible that some of the parents had food allergies when they were young , but then theseallergies went away , and the parent were never re - tested for the allergies , the researchers said .
The parents in the study were still more likely to examine positive for solid food allergy than people in the general population . For example , nearly 9 percent of all parents in the study test positive forpeanut allergic reaction , but only 7 percent of hoi polloi in the oecumenical population are allergic to Arachis hypogaea . However , " these actual differences are more modest than one might require if intellectual nourishment allergic reaction is highly ascertain by genetics , " the researchers drop a line .
The investigator noted that they did not practice a so - called " food challenge " run to confirm if the parent had food allergies . During this kind of trial , mass are gift small amount of the nutrient they intend they are allergic to , and monitor closely for a chemical reaction . This test is considered the " gilded monetary standard " to confirm if a person has a food allergic reaction , the researcher said .
More allergic reaction study in grownup are needed that use a intellectual nourishment - challenge test to better understand the preponderance and heritability of food allergies , the researcher said .
The study was conducted by researcher at Northwestern University Feinberg School of Medicine , Johns Hopkins University and the Children ’s Hospital of Chicago .
