Leading Experts Rethinking Food Allergy Causes

The perplexing world of childhood food allergies is enough to make any parent break out in hives.But conventional wisdom is now being questioned when it comes to bottle-feeding whole milk to babies or keeping toddlers away from the peanut butter jar.
With an alarming increase in childhood food allergies and record numbers of parents heading to the doctor's office with concerns that their children are allergic to a long list of foods, a team of leading childhood allergy experts says the way we prevent food allergies is misconceived, The New Yorker reports.
Dr. Hugh Sampson, director of the Jae Food Allergy Institute at Mount Sinai Medical Center in New York, tells the magazine new research is producing some unexpected findings, mostly that, contrary to popular belief, early exposure to allergies may prevent food allergies later on.
Though he believed for most of his career that children are far less likely to become allergic to problematic foods if they are not exposed to them as infants, Sampson tells The New Yorker research is proving him wrong.
Sampson and Dr. Scott Sicherer, a pediatric allergist also at Mount Sinai, have conducted extensive studies throughout the United States that show that the rate of allergies is rising sharply.
They estimate that 3 to 5 percent of the population is allergic to milk, eggs, peanuts, tree nuts or seafood, according to the magazine.
"This increase in the incidence of food allergy is real," Sampson tells The New Yorker, but he adds that he can't say what is causing the increase, just that he now thinks the conventional approach to preventing food allergies is questionable.
In fact, the Mount Sinai team tells The New Yorker they believe early exposure may actually help prevent food allergies later in life.
Previously, Sampson says, his research in the 1980s looked at whether the problem of allergies could be prevented if mothers continued breast-feeding as long as possible. Laboratory studies reinforced the theory, he tells the magazine.
"From an evolutionary-biology point of view, food allergy makes no sense at all," co-researcher Sicherer tells The New Yorker. "It seems pretty clear that food allergy is a condition that resulted from the environment we created."
Now, experts believe, a child becomes tolerant to a variety of food proteins through exposure in the first six months of life and some 80 percent of infants who are allergic to eggs or milk will outgrow the allergy by their teenage years.

Gabrielle said...Dealing w/ food allergies is tough 2 of my 3 kids have many food allergies: milk, eggs, sunflower, peas are difficult. But I go to the grocery store alone & am the sole grocery shopper so I can read ingredient lists on everything. You can find almost anything like cookies, cakes, & snacks... That are allergy free.. You just have to take your time read & shop.

AZ said...Whomever wrote this article is a complete moron and a danger to infants and toddlers, and children. Clearly this "expert" has never had a toddler go into anaphylatic seizure from being in a baseball stadium where there were peanuts on the floor. This article is irresponsible and should be removed. Does this "expert" have a medical degree or any experience as an allergy specialist? It is a real insult to those of us who have raised children with severe food allergies that are life threatening. We are vigilant night and day to keep the peanuts and so forth away form them, yet some parents don't consider peanut butter cookies as an allergin, because there are no "nuts" ON them! Remove this article before someone naieve reads it and actually believes it. It is an outrage.

colleen said...Yes AZ the statements are from " Dr. Hugh Sampson, director of the Jae Food Allergy Institute at Mount Sinai Medical Center in New York" This man is a leading expert on allergies in children. YOU are an expert on your 2 children. Don't confuse the masses with your own experience!

Steve said...@AZ: If you did something as simple as READING the article, you would have read that they said "...a child becomes tolerant to a variety of food proteins through exposure in the first six months of life and some 80 percent of infants who are allergic to eggs or milk will outgrow the allergy by their teenage years." Meaning, if you can comprehend this, you would have had to start exposing your child as an infant. But I'm gathering your child is no longer an infant, not even a toddler. Probably what? 5 or 6? It's probably too late for him, as he didn't build the immunity that we would have as an infant. So yes, exposing children (not infants) to things they are allergic too would be harmful, because they never had the opportunity to build immunity. Kinda like playing your lottery numbers after the cut off time. It's too late.
So next time you start going off on a tangent and calling people who are far more qualified in this field than you morons, you may want to think before you speak. Moron.

mom said...My question on this article...How do you introduce these "foods" at 6 months? My doctor had all 3 of my children on nothing but breast milk or formula at this point. Then adding only cereal. So I don't see this as realistic introducing these"foods" at that early of an age.

Amy said...Mom - Aren't children exposed to what you eat through breast milk? If that is true, I suspect that is what they mean by exposure to the foods in the first 6 months.

SB said...AZ, why would you take your child to a baseball park knowing there were peanuts on the floor and peanuts sold there if your child was severely allergic to peanuts? How can you blame the stadium for your own lack of judgement? I'm not saying the child should live in a bubble, but jeesh, sounds like you are the problem with that scenario.

Nikki said...Sometimes one can't help laughing when one hears ridiculously obvious product-warnings, but AZ's response to this article reinforces my belief that there SHOULD be better-trained science/medicine reporters...reporters (or at least their editors) who know the caveats that should be included in a story. True, AZ is not a competent reader or s/he would have easily noted the expert's position as well as the proviso that potential allergens be introduced in infancy -- NOT after a full-fledged allergy has been diagnosed. Who knows? Maybe AZ is just one of those seriously neurotic hyper-conscious parents who seizes any (befuddled) excuse to announce that s/he is a (good) parent. (You know: the ones who also talk way too loud to their children in stores?) Still, I'm pretty confident that even SOME infants might actually have early-onset (even pre-natal) allergies. Given that allergic reactions can be extremely serious, any thinking reporter/editor -- recognizing that there are many interested parent-readers -- might include a brief conclusion suggesting that these are the results of an INITIAL study and that concerned parents might ask their pediatrician about this new research and whether/how potential allergens might be introduced into their infants' diets. It IS scary that, on the basis of this careless report, some idiots might presently be grinding up peanuts to mix into the applesauce. Just saying.

aet999 said...i know several moms whose kids are allergic to "everything". They were what I refer to as "breast-feeding nazi's". They breast fed their kids for years, compulsively disinfected everything in their homes, kept their kids home in the winter, etc. I breast fed for 1 year, but not exclusively. I exposed my kids to everything. My kids have no allergies. My kids rarely get colds in the winter. I am a firm believer that their early exposure to things is a big part of why they do not have allergies. The moms that are posting things like "my kids allergies are real", no one is saying they aren't, But maybe if the advice you had been given when they were infants was different, they wouldn't be allergic now, or it wouldn't be so bad. No one is saying early exposure would prevent ALL allergies. Some kids will get allergies anyway. I, myself, was allergic to milk as a child, but I did grow out of it.

dontuvvish said...Food allergies run in my family. My brother and I are both allergic to shellfish. My niece is allergic to shellfish and peanuts.
I have a four-month-old son, but since he's not on solid food yet, I don't know whether he is allergic to anything. I am hoping and praying he is free of it, especially peanuts, because that's among the deadliest food allergies. I'm not trusting what some AOL article says, so I'm talking to his pediatrician.

Abraxus said...I have food intolerances, which are the same as allergies only it's like you start with an empty bucket and the more things that you are intolerant of that you eat/drink, the fuller the bucket is and the worse you feel. MANY children diagnosed with allergies and ADHD etc, should really be checked for dietary problems that cause their other issues. I am Salicylate intolerant - Google it and you'll find tons of info about symptoms etc. Symptoms include things as bad as anaphylactic (spelling?) shock, or more milder like hives, or other things like asthma attacks, irritable behavior, headaches, stomach issues, behavioral problems. And this is from all kinds of natural healthy foods - I cannot even be around the smell of fresh oranges, cannot eat broccoli, artichokes, cannot have spices of any kind, cannot eat gravies, no potato chips, no fruit juices, the list is endless - but once you start only having the low end reaction stuff you sleep better, behave better, scratch less or no at all, asthma can disappear totally. It's worth checking out for anyone who is unsure on the allergies their kids have and wants to talk to a doctor more about this!

Heather said...We have food allergies in our family. My daughter and I are both allergic to shell fish, oranges, stawberrries. She is a little allergic to peanuts. Her allergies have gone up and down over time. The peanut allergy has gotten better. I have never isolated her or myself from our allergies. I don't eat the food I am allergic to and she limits what she eats. I have always had peanut butter in the house and her allergy is very minimal now. She can eat 2 sliced of an orange and be ok.
My sister who has completly avoided her allergy triggers has just gotten worse. Now she can't even be in the room with someone eating corn.
When you get an allergy shot they are slowly exposing your immune system to the allergy and that causes you body to build up a tollerance.that is what people hould be doing. I am not suggesting eating the trigger but just don't avoid it completly.

TNM said..."A little allergic to peanuts"? I hope you're more careful with your child's peanut consumption than your attitude shows here. Peanut is the most FATAL food allergy while milk is the most common food allergy. I've been an allergy nurse for 3 years and have seen a lot of food allergies and done thousands of allergy tests (skin prick and blood testing) for food allergies. Please tell me there is an epi-pen (epi-pen jr if under 66 lbs) in your home--preferably two, because you usually need both doses of epi with food anaphylaxis. There are no allergy shots for food allergies--avoidance is the best policy. DO NOT LET YOUR ALLERGIC DAUGHTER EAT PEANUTS!! Check out www.foodallergy.org for tons of useful information regarding management of food allergies. Please just be safe!

Kelly said...Yes, you can be a "little" allergic to peanuts. My son will break out in a mild case of hives every 4th or 5th time he eats peanut butter which is his favorite food in the whole world. They aren't severe and he has the blessing of his allergist from the Cleveland Clinic to continue eating it. It's alarmists like you who try to get peanut butter banned from schools. If your child is severe then yes stay away from it but not everyone with an allergy needs to. If it's a mild allergy it's perfectly fine to be exposed in moderation. I'll have faith in my allergist from a world reknowned medical facility over someone claiming to be a nurse on the internet. Talk to your own doctors. Don't take the info on the internet as gospel. Everyone's allergies are different & you and your doctor know what your reactions have been & what they'll likely be in the future. It's not black & white no matter what the alarmists will try to tell you.

chrstdyd4yu said...I think the real issue here is not really that anyone is wrong but the far too broad use of the word allergy. Really in a perfect world the nurse is correct someone with an actual peanut allergy should never be exposed. As an actual allergy will always have a strong immune response, these can range from mild to severe but with an actual allergy testing this is exremely dangerous once it is developed, as with a "full food allergy" your symptoms actually worsen with exposure. Now an intollerance is different. An intollerance can be improved upon with exposure. And both can be avoided or improved upon with exposure during infancy, via breastmilk and other simple avenues. The lack of breastmilk containing these "particles" and enzymes to break them down, when in infant has an allergic or intollerant mother who is avoiding those foods may actually be the reason for allergies appearing in families. Such as the Mother heather was trying to explain...by attemping to expose her intollerant daughter to these foods she has succeeded in decreasing her intollerance where as the mother is still stuck at a point of severe intollerance or food allergy. This is actually good parenting :D Just as I nor my cousins are allergic to shellfish even though my grandmother and her daughters are, because our parents allowed us to experience those foods even though they had an allergy. This is a new way of thinking but it makes perfect sense. If an allergy is already developed KEEP YOUR CHILD AWAY FROM THE ALLERGEN.
