For year , parents have been recount to keep back earthnut from their shaver until the old age of three , to prevent the onset of life-threatening peanut allergies . A landmark study is now throw this conventional wisdom on its headway , instead indicate that most goober allergies can be staved off by introducing monkey nut to nestling early .
The prevalence of earthnut allergies among children has been rising steady for years , especially in the West . It ’s also starting to appear in Africa and Asia . In the U.S. , for example , the number has more than quadruple since 2002 , grow from 0.4 % in 1997 to 1.4 % in 2008 to more than 2 % in 2010 . For Americans , it ’s now the leading cause of nutrient - link up anaphylaxis and death .
Back in 2000 , the American Academy of Pediatrics ( AAP ) told parents to stop feed peanut vine and peanut products to their nipper until they reached the eld of three . Despite this , prevalency rates of groundnut allergic reaction continued to rise , and by 2008 , the AAP had retracted its good word for deficiency of cogent evidence . At the same meter , correlative studies were starting to show that allergic reaction rates were high among populations practice other solid food - shunning compared to those who were not . What ’s more , some study show that early introduction of egg and Milk River could be associated with a decrement in related allergies .
Thenew study , which appears in The New England Journal of Medicine , is now provide some concrete grounds . In a controlled trial , a group of 530 babe aged 4 to 11 months at high endangerment of develop goober allergies ( determined via skin - prick test ) were arbitrarily assigned either to be fed food with peanuts ( phthisis mathematical group ) or peanut - free foods ( avoidance mathematical group ) . The children were fed at least six grams of peanut protein each week , about 24 peanuts ’ worth .
This function on until they reached the eld of five . Around 10 % of the nipper were finally eject from the study for care of severe reaction .
The result were striking : By age five , the overall preponderance of peanut allergy in the avoidance mathematical group was 17.2 % . In the consumption grouping , it was 3.2 % . For those kid who initially had a negative event on the skin - prick test , the prevalence of peanut allergy was 13.7 % in the avoidance chemical group and 1.9 % in the consumption group . For those with mild sensitization to the tegument - prick tryout , the prevalence was 35.3 % in the avoidance chemical group and 10.6 % in the uptake mathematical group . The report seems to once and for all demonstrate that early peanut consumption is an effective form of allergy bar not just for gamey - peril infants , but in infants with modest to moderate peanut sensitivities , as well .
As the author conclude in their field : “ The other introduction of peanuts significantly decreased the frequency of the development of Arachis hypogaea allergic reaction among tiddler at high risk for this allergy and modulated immune response to peanuts . ”
The New York Timesgoes over some of the work caveats :
parent knew which radical they were in . And the study was done at a exclusive internet site in London with 75 pct snowy children . However , the results were the same for the lowly number of children of other ethnic groups in the subject field , the researchers said .
Moreover , it is still unknown whether allergy might yet build up if the even feeding of peanut quit . To try this , the tiddler in the written report were taken off goober pea after they turned 5 and are being followed for a year .
It is also strange if the same strategy would work with other food or for children not considered at a high risk of getting a peanut allergy . Some pediatricians say that if run goober food to children at risk was good , there would be no reason to deduct such solid food from children not prone to allergies .
Inan editorialprepared by the NEJM , the author had this to say about the subject area ’s implication :
Should we recommend introducing monkey nut to all babe before they strain 11 months of age ? Unfortunately , the answer is not that simple-minded , and many questions continue unreciprocated : Do baby require to ingest 2 g of peanut protein ( approximately eight peanut ) three times a week on a regular basis for 5 year , or will it serve to consume lesser amount on a more intermittent basis for a short menses of meter ? If regular goober pea consumption is discontinue for a prolonged period , will allowance persist ? Can the findings of the LEAP survey be put on to other food , such as milk , eggs , and tree diagram nuts ?
The author trust to see these interrogative sentence addressed in succeeding studies , but because the outcome of their trial “ are so compelling , ” and because the rising rate of allergy are “ so alarming , ” they desire to see formal guidelines introduce in the near future . In the interim :
we suggest that any infant between 4 months and 8 month of age believe to be at risk for peanut allergy should undergo skin - bastard testing for peanut . If the trial run termination are negative , the small fry should be set out on a diet that includes 2 g of peanut protein three metre a workweek for at least 3 years , and if the results are positive but show balmy sensitivity ( i.e. , the wheal measures 4 millimeter or less ) , the child should undergo a intellectual nourishment challenge in which Arachis hypogaea is administer and the child ’s reply observed by a physician who has experience perform a food challenge . Children who are nonreactive should then be bug out on the peanut - incorporate diet . Although other studies are urgently needed to address the many question that stay , specially with respect to other foods , the LEAP study make it clear that we can do something now to countermand the increasing prevalence of Arachis hypogaea allergic reaction .

intelligibly , given just how entrenched the “ do n’t feed peanuts to your infants and bambino ” meme is in our acculturation , it ’s going to take a recollective time to overturn .
