Fruits, vegetables may trigger child allergies

Previous studies had indicated that eating fruits and vegetables could reduce the risk of children developing allergies, but a study headed by Dr. Helen Rosenlund of Stockholm's Karolinska Institute has discovered a surprising connection.

Fruits and vegetables are rich in antioxidants, which are believed to decrease airway inflammation. Recent studies reported that children who consumed more green vegetables had fewer cases of asthma, wheezing and hay fever.

However, in Rosenlund's research, which was published online by the Journal of Allergy and Clinical Immunology last month, certain proteins in fruits and vegetables such as apples, pears and carrots are similar to the pollen parts that trigger hay fever.

As such, children can react to both, meaning that pre-existing allergies may have caused them to "eat around" the greens.

"This could confuse research findings, falsely suggesting that diets with fewer fruits and vegetables result in more allergic disease," Rosenlund told Reuters on Thursday.

Rosenlund and her colleagues investigated the association between current fruit or vegetable intake and allergic disease in eight-year-old Swedish children to evaluate the potential effect of disease-related modification of consumption.

They examined the data of 2,447 subjects who had participated in a larger Swedish study since birth. Blood tests and questionnaires filled out by parents revealed that 7 percent of the children had asthma, while hay fever and skin rashes were more than twice as high.

Each child ate an average of one to two servings of fruit and two to three servings of vegetables on a daily basis, according to the study.

Initially, the vegetables appeared to help. The children who ate the most fruit were two-thirds as likely of developing hay fever than those who ate the least amounts of fruit. Apples, pears and carrots were particularly helpful, but there was no connection to vegetable consumption.

However, half the children with hay fever were sensitive to birch pollen, which resembles proteins in apples and carrots. After comparing the results without the children with food-related allergy symptoms, the researchers could find no link to hay fever.

Story continues below…

Researchers suggest studies in other parts of the world may demonstrate a different variety of allergy triggers or allergens and urge them to look at how allergies influence the consumption of individuals.

The study was supported by the Stockholm county council, the Heart and Lung Foundation, the Swedish Asthma and Allergy Association, the Swedish Foundation for Health Care Science and Allergy Research and the Swedish Research Council.

One researcher has received lecture fees from MSD and is a consultant for AstraZeneca, but the other the authors have declared that they have no conflict of interest.

Would love to know how they managed to filter out all the other environmental variables in such a small sample size. Also (bad reporting!), where are the reported statistics about how significantly the effects of eating fruit & veg are i.t.o. allergies.....0,001% higher, 0.01 % higher, 1% higher...?

We all know that some people break out in hives from strawberry consumption, severe asthma from eating peanuts as well as various other negative reactions to fruit and vegitable ingestion. On the other hand, I've NEVER heard of an allergic reaction to meat consumption. The facts speak for themselves.

Let me guess what the next step is.

They are going to advise people to eat in mac Donalds instead.

At least the photo accompanying the article doesn't have the little girl eating the banana. Someone would scream child pornography.

You sure that is a boy eating the banana?

no use going to maccas coz their food is full of weird stuff!

better to get your own food these days,

see swedishmealtime on youtube for inspiration! aaarrrg alskar ketchup ROFL!

what is one mans meat is anothers poison!
08:13 February 14, 2011 by JulieLou40
@ markinboston:I agree!

Personally, I'm more concerned that the boy in the pictures has what looks like cheap nickel jewellery shoved through his ear-which is a hell of a lot more likely to cause an allergy than a frickin' banana. Good God, the world has gone mad. People get paid to "research" this crap??

But the young Banna-Eating-Boy has an Earring?

Oh, I forgot, It's Sweden : )

I guess He won't get bullied fro the other kids albeit, no pink clothes & painted nails here.

Fruits, vegetables may trigger child allergies; and then the research is narrowed to apples, carrots and pears.... What a bunch of idiots!!!

This research is simply embarrassing! Scientists always claim that Mediterranian diet is the best for people's health, which means lot of vegetables and fruits, enough cereals, pasta and bread, often fish, meat (better white) only three times a week and no butter, just olive oil.

Who paid you to publish this!

What parents need to worry about is putting their kids in mite infested beds and pillows and a mouldy old house with leaking water pipes. That is what causes allergies. And not to forget animals, they've got lots or allergens in their saliva and dandruff.

Mites, moulds and cat allergens are the most common allergens and often if these are reduced the allergic reactions get reduced.

But hey who is going to listen to this?

If food can be blamed do so; it is either good for you or it is a super food or it is bad for you. A little bit of what you fancy does you good - 'little bit' being the operative word! But not when it comes to fruit and veg - eat plenty of these - leafy, couloured etc.

Just one last point: it is when a person is exposed to huge amounts of an allergen, especially when they are children, that they become allergic. That is why a child can become allergic to cow's milk if it is not breast fed.

I can download a book on this if you like!

Are vaccines responsible for the epidemic of anaphylaxis in young children today?

In the presentation speech as winner of the 1913 Nobel Prize in Medicine for his work with anaphylaxis, Charles Robert Richet said, "We are so constituted that we can never receive other proteins into the blood than those that have been modified by digestive juices. Every time alien protein penetrates by effraction, the organism suffers and becomes resistant. This resistance lies in increased sensitivity, a sort of revolt against the second parenteral injection which would be fatal. At the first injection, the organism was taken by surprise and did not resist. At the second injection, the organism mans its defences and answers by the anaphylactic shock." In naming "anaphylaxis", Richet described, "Phylaxis, a word seldom used, stands in the Greek for protection. Anaphylaxis will thus stand for the opposite. Anaphylaxis, from its Greek etymological source, therefore means that state of an organism in which it is rendered hypersensitive, instead of being protected." Richet concluded his lecture by saying, "Seen in these terms, anaphylaxis is a universal defense mechanism against the penetration of heterogenous substances in the blood, whence they can not be eliminated."

Vaccine antigens injected subcutaneously or intramuscularly prompt the immune system to create antibodies in the blood against those antigens. Has medicine, which has used vaccinations containing "alien proteins" as its cornerstone to control infectious diseases, been on the wrong track by injecting heterogenous substances [originating in an outside source; especially: derived from another species] into human beings to "control" disease? What would be the general state of health today if 200 years ago medicine had taken the path of discovering the keys to promoting a strong, unadulterated immune system in conjunction with increased nutrition, vitamin and mineral supplementation along with better sanitation? Has medicine produced false protection by injecting alien proteins via vaccination which, as Richet pointed out in his lecture, can render us hypersensitive instead of being protected?

This hypersensitive state called anaphylaxis is now epidemic in young children who live every day of their life under threat of death from everyday, normally harmless substances. The numbers are staggering. According to Health Canada's web site, "It is estimated that 600,000 Canadians (two percent of the population) may be affected by life-threatening allergies, and the numbers are increasing, especially among children." In 2005 Ontario passed a law to protect anaphylactic students at school while The Toronto Star reported an estimated 40,000 children in Ontario with anaphylaxis.

"Are vaccines responsible for the epidemic of anaphylaxis in young children today?"

In the absence of statistical data to the contrary,

a ) which epidemic

b ) No.

Note to self: never let children eat whole bananas in public.

This study must have been paid for by the likes of McD's cos it's certain that no one could be allergic to all the colourings, preservatives, additives they incorporate in the crap they sell.

Natural News online reported on the 26 of January 2011 by Mike Adams "The Health Ranger" and editor of Natural News; an article titled "Documents Emerge Prpving DR Wakefield Innocent; BMJ and Brain Deere Caught Misrepresenting Facts." There is now new evidence from documents that emerged, clearing any allegations against Dr Wakefield. The allegations of fraud made by the British Medical Journal and the investigative journalist Brian Lawrence Deere, were proven false when these documents proved they misrepresented Wakefield's study findings. Wakefield commented:

"...Completly negates the allegations that I commited scientific fraud. Brian Deere and Dr Goodlee of the British medical Journal knew or should have known about the fact set out before publishing their false allegations."

1996 December 20, a meeting was held of The inflammatory bowel disease study group at the Royal Free Hospital Medical School. This featured a presentation; given by Proffesor Walker-Smith; on 7 of the children that later appeared in Dr Wakefield's group of patients for his study. Wakefield had been accused of " completely fabricating"the link associated with Autism from the MMR vaccine in his findings. 14 months before; however, the 2 researchers Professor Walker-Smith and Dr Amar Dhillon, had found and documented the same issue in children which included autistic symptoms.

Professor Walker-Smith's presentation notes in 1996 of Entero-colitis and Disintegrative Disorder Following MMR- A Review of the first Seven Cases, begins with:

"I wish today, to present some preliminary details concerning seven male children who appear to have entro-colitis and disintegrative disorder, probably Autism, following the MMR."

He did give the clinical history of the seven children and it was detailed by his medical team and senior pathologist, Dr Amar Dhillion. Wakefield was NOT a part of this study and actually independently REPLICATED the study with his own research medical team. Anderson Cooper claimed when interviewing Wakefield, no repliation of the study was ever done. Wakefield was interreputed many times when he tried to state it was indeed replicated. Notes on the seven children were given and correction for the mistakes also noted. This also vindicates any allegation that Wakefield had misrepresented any clinical history.

Among some of the findings in the kids and the medical history they had regression within a month of the shots, high fevers immediately after the shots, all had stomach and bowel problems, head banging within two weeks etc. This can be found on Natural New's website reported by Mike Adams.
