BBC News – Hopes rise for low allergy peanut

How amazing could this be?

If they can create a peanut that is low allergy, when will they be able to create one that is NO allergy?

I know there is the camp that is against the whole genetic manipulation of food, but it’s very cool and promising.

Besides, genetically modifying food and plants may lead us to some very important medical discoveries!

Researchers are working on peanuts that are low allergy, which could put an end to the problems the popular seed can cause.

Through mixing varieties, the US team has managed to remove or reduce key proteins thought to spark the allergy.

They stress the resulting peanuts are not genetically modified but the product of conventional cross-breeding.

Peanut allergies are relatively common and usually cause breathing problems.

But at their most serious, they can lead to a potentially life-threatening anaphylactic shock.

Peanuts lead allergy list, national survey finds

The Toronto Star’s Health Zone reminds us just how many kids are nut or peanut allergic.

Canada’s first nationwide food allergy survey shows that about 1.7 per cent of children under 18 have a probable peanut allergy, while another 1.59 per cent have a probable allergy to tree nuts, such as hazelnuts and walnuts.

This study was from 2008-2009 and was conducted over the phone to 10000 families. That’s a good sized sample and shows that a great many children are affected.

It’s also notable that there is a great difference between results in the US and Canada.

He says the rates are higher in Canada than in the U.S. — a 2002 American study found that 0.83 per cent of children have peanut allergies and 0.51 per cent are allergic to tree nuts.

Keep in mind the time between studies. It is possible for those results to have changed in 6 years.

Food Allergy Complexity: More Than Meets the Eye, by Margaret Pingolt

Margaret Pingolt is a journalism student at Arizona State University. She requested a few questions answered from yours truly for an article she was working on. Below is a wonderfully written piece on college age people and life away from home.

Thanks, Maggie!

By, Maggie Pingolt

PHOENIX- Waking up the day of high school graduation is typically a gift from the gods, a chance to leave the confines of an underage life with parents.  For some with food allergies, it’s just another day of heightened awareness.  One misstep at the party buffet and the night is ruined in hives, sneezing or anaphylactic shock.

Going to college is a difficult tradition in and of itself.  In addition to a life threatening condition like food allergies, teens and young adults are at the highest risk of death because of vehicle accidents, drug overdose, and alcohol intoxication.

Immunotherapy may reduce peanut allergy

The Toronto Star’s Health Zone has started a series of food allergy related articles in responce to Food Allergy Month.

This article reviews a new study from Mcmaster University and Dalhousie University in Halifax where 30 children with peanut allergies are going through the ingestion immunotherapy process.

One notable difference in thsi study compared to the one done in the US is that they will be allowing in children with severe reactions. The study in the US worked only with children whose allergic reactions were mild.

Book – The History of the Peanut Allergy Epidemic

Available in real paper (not as an e-book), this book offers a glimpse into the history of the peanut allergy.
I hope to have a review up in the near future, but in the mean time pick up a copy and tell us what you think.

The History of the Peanut Allergy Epidemic, the first documented history of the rise of peanut allergy, is now available http://www.peanutallergyepidemic.com

Written by Heather Fraser a Toronto-based historian and mother of a peanut-allergic child, this meticulously researched book pinpoints the moment of the allergy’s appearance and reveals the perfect storm of social, medical, political and economic factors from which the epidemic has grown.

The epidemic proportions of peanut allergy have spawned intense research into numerous risk factors including peanut consumption, birth month, hygiene, parasite levels and even head size.   And yet, no one has been able to connect the specifics of this surprising epidemic with a functional mechanism of sensitization – how have 2 million children in just the last 20 years become sensitized to this one food?  Neither coincidence nor genetic fluke can explain the speed at which this allergy has spread in children or its peculiar features.   The allergy appears primarily in western countries including the US, Canada, Australia and the UK and in toddlers, boys more often than girls in a ratio greater than 2:1.

The history of food allergy provides some answers starting with Charles Richet who coined the term anaphylaxis in 1913 to describe a sudden and unexpected prevalence of mass allergy related to pharmaceuticals.  Clemens von Pirquet in 1906 called these altered reactions in children allergy.  Combing the literature, Fraser discovered that outbreaks of peanut allergy began to occur only after WW II.  There was a slow but noticeable growth of the allergy in children through the late 1960s up until about 1989. Around 1990, there was an explosion of this allergy just in toddlers.  This moment is well documented by ER records, cohort studies of the time and eyewitness accounts.  Society only recognized the epidemic when this mass of allergic kids showed up for kindergarten.

The surge of peanut and food allergic 4 and 5 year olds took everyone by surprise – school systems, teachers, parents, entire communities.  And it has persisted and worsened.  An estimated 2% of kids living in the US and Canada are peanut allergic.  A 2010 Australian stat indicated that 3% of children living there are allergic to peanut.

How has this happened?  Functionally, there are a limited number of ways in which a person can become anaphylactic to any protein – ingestion, inhalation, through the skin and injection.  Historically there was only one mechanism implicated in mass allergy.  This together with a series of swift, identical alterations in political, social, legal, medical and economic conditions in western societies between 1987 and 1994 the peanut allergy in children tipped into epidemic….  Events unfolded in plain sight.

The History of the Peanut Allergy Epidemic (Innovation Press, 2010) is a must-read for every parent, teacher, and health professional.  Heather Fraser, MA, BA, B.Ed is a Toronto-based writer.  The book consists 211 pages with endnotes, index and appendix showing the global prevalence of the allergy.  Book is $19.99 and available for purchase http://www.peanutallergyepidemic.com

Peanuts, Anyone? Researchers Expose Kids to Risky Foods in Order to Cure Them – washingtonpost.com

Oral immunotherapy is still in the research stage, but any news is good news. Knowing that this possible treatment is on the way with funding to keep it alive makes us all very happy.

Ever since she was an infant, Reagan Roberts could not tolerate being anywhere near cow’s milk. A mere sip would leave her vomiting and gasping for breath. If she were even touched by someone with milk on their hands, she would break out in hives and a bright red rash.

HealthGuru.com: Ancient Chinese Secret for Peanut Allergy

The herbal remedy from China isn’t new news but it is new that the FDA has been given drug approval! Read on for more promising news.

An investigational drug, FAHF-2, has been given new drug approval by the FDA. The herbal remedy shows great promise in reversing anaphylaxis, a severe and life-threatening reaction to peanuts that can result in death. In clinical trials in mice, the herbal remedy has been shown to prevent anaphylaxis for more than 9 months after the treatment was stopped.

Food allergies have been on the rise for several years. Peanut allergy doubled in children between the years 1997 and 2002. It is estimated that 150 people die every year in the US as a result of food allergies. Even trace amounts of these foods can cause a life-threatening reaction. There is no cure for food allergies. People who suffer food allergies must practice strict avoidance of known triggers and seek help immediately if food is accidentally ingested.

Anaphylaxis is a serious allergic reaction that can occur extremely rapidly and can result in death if not treated immediately. People who have asthma in addition to food allergies may be at higher risk of suffering a severe reaction. The following symptoms may occur in an anaphylactic reaction:

Itching, tingling or metal-like taste in the mouth

Hives

Wheezing or difficulty breathing

Swelling of the mouth and throat

Low blood pressure

Loss of consciousness

The herbal remedy for peanut allergy, as well as a remedy for asthma, is currently being tested on humans.

Nut allergy ‘hits Asian children’

This article is based on only 2 clinics in London, England seeing an increase in nut allergies. It needs more research since there can be many reasons why this could be happening. The research needs to include many more clinics.

A disproportionately high number of Asian children are being diagnosed with nut allergy, a leading expert says.

Dr Abbass Khakoo, medical director at London’s Hillingdon Hospital, is a specialist in food allergies.

He said children from ethnic minorities were over-represented at his two London clinics.

He has found children from ethnic backgrounds appear to display symptoms of nut allergies at a younger age than their white counterparts.

Obese children more likely to have food allergies

This is an interesting discovery. It’s interesting also that of all the people I know who have food allergies, none of them is of larger than average size. 

Obese children and teens are 26 per cent more likely than kids of a normal weight to have some kind of allergy, especially a food allergy, U.S. researchers report.

But it is not yet clear if obesity actually causes allergies; only an “association” between obesity and allergies was found, said Dr. Darryl Zeldin, the senior author on the paper.

Man died an hour after being treated for peanut allergy

This tragic story has to be told. Why do health professionals feel that a study that is still in it’s infancy is safe to practice on patients? This should never have been done, let alone on someone who is known to have severe allergies to peanuts. I stronly urge anyone who is approached by thier allergenist to consider this story. 

A man who suffered from a peanut allergy collapsed and died from severe anaphylactic shock less than an hour after receiving treatment for his allergy from an alternative medicine practitioner.

Chinese Botanical Drug to Cure Peanut Allergies

Herbal medicine has been around, well, forever and many of today’s drugs are herbal based, so we should not be surprised that there may be a natural source for controlling allergic reactions. This sounds interesting. The drug seems to counter the effects of anaphylaxis that is brought on by eating peanuts.

A recent study conducted at Mount Sinai School of Medicine in New York suggests that a Chinese botanical drug can help patients manage their food allergies. This new drug may help many allergic patients in the western society and could also assist in curing other conditions such as asthma.

Food Allergy Labeling Not Always Accurate

This is quite allarming and why we need to know what companies we can trust. This is also the reason we need to push our governments for stronger labeling laws.

MONDAY, March 16 (HealthDay News) — A small number of food products with a “may contain” label actually do contain an allergen, while about 2 percent of foods products without such a claim also contain allergens, new research shows.

Black male children are four times more likely to have food allergies: study

Black male children are at an especially high risk for developing food allergies, according to a new study presented Tuesday in Washington, DC, at the annual meeting of the American Academy of Allergy, Asthma and Immunology.

They’re about four times as likely to be food allergic as the rest of the population, says Dr. Andrew Liu, a co-author of the study, which he says was sponsored by the National Institutes of Health.

The Canadian Press: Mixed reaction from parents on peanut allergy advance; many remain dubious

I think that anyone who has peanut allergy, or has someone in the family with peanut allergy would jump on this study. In my own family I thought that YES, finally, a move forward, lets get on it! My wife, on the other hand wanted to know much more. Side effects, how many kids dropped out, reactions versus no reactions… All they tell you in the press releases is the good in these studies and not the bad.  For parents and individuals to feel comfortable the full scope of the study needs to be made available.

I’ll continue to try to locate the results but please exercise caution and ask many questions before jumping into this kind of study. DO NOT TRY THIS AT HOME. The doctors and researchers are using very measured doses and processes to do this study. This could be dangerous if not fatal to attempt this on your own.

CONCORD, N.H. — One mom says she’d be first in line for a promising treatment that exposes children with peanut allergies to tiny amounts of peanut flour. Another remains fearful, with the painful image of her son’s face blown up beyond recognition still fresh in her mind.

While some parents of children with life-threatening peanut allergies see a glimmer of hope in a recent study suggesting a possible cure, others remain dubious that it will ever change their children’s lives.
