Soy and the Odwalla Chocolate Protein Monster

Soy and the Odwalla Chocolate Protein Monster

Odwalla’s Chocolate Protein Monster made the news last week when four consumers experienced severe allergic reactions.   This set off  a “nationwide allergy alert”, a product recall and a lot of speculation about what might have caused the reactions.   Although all four of the victims were allergic to peanuts, and two were also allergic to tree nuts, the drink contained neither peanuts nor tree nuts.   There was also no evidence of accidental or malicious cross contamination at the manufacturing plant.

With the possibility of contamination from peanuts unlikely, detectives are considering the potential for cross reactivity.    Cross reactivity refers to a reaction that occurs when people allergic to one class of proteins react to another similar in structure.   A good example is soy and peanuts, members of the grain-legume botanical family.   In fact, scientists have known for years that people allergic to one are often allergic to the other.   Food safety experts say they are clueless as to what might have happened in the Odwalla case, but given that the Chocolate Protein Monster drink contained soy protein, and the victims all suffered from peanut allergies, the likely culprit is soy.

Severe reactions to soy were once rare.   Today they are increasingly common, and pose especially high risks to children already afflicted with peanut allergies.   In 1999, the journal Allergy reported that four children in Sweden died after eating a minuscule amount of soy “hidden” in hamburgers.    The Swedish National Food Administration promptly warned parents and pediatricians of the soy-peanut link, and stated that children suffering from both peanut allergy and asthma are at very high  risk.   Additional risk factors reported included other food allergies, a family history of peanut or soy allergies, a diagnosis of asthma, rhinitis or eczema, and/or a family history of those diseases.    The researchers found it took only a tiny, almost indiscernible, amount of soy to create a severe and even life-threatening reaction in susceptible individuals.   Even more surprising, they discovered severe allergic reactions could happen suddenly and unexpectedly to people with no known soy allergies.    In fact, the reactions documented by the Swedes were very similar to the reactions to the Odwalla Chocolate Protein Monster drink.

Tragically, the Swedish National Food Administration warning has not been publicized much in the U.S.   Indeed, the Soyfoods Association of North America —  and even many allergy support groups —  recommend soy nut butter and soy nuts for children allergic to peanuts and tree nuts.   As a result, few people have heard of the deadly soy/peanut connection, and numerous adverse reactions have been reported.

Even worse, we know for certain of several deaths.

Six years ago, 13-year old Emily Van Der Meulen died on April 13, 2006.   Emily had a severe peanut allergy and assiduously avoided peanuts, but did not know she should also have avoided soy.   She died after eating a meal that was apparently peanut free but contained a tiny amount of soy.  Just as in the Swedish study, she had not previously reacted to soy.

After Newsweek ran a cover story on the growing threat of food allergies to children, Emily’s parents Paul and Catrina Vonder Meulen spoke up to warn people about soy:

“The Newsweek article talks about the growing threat of food allergies but with no mention of soy.   Soy is a silent killer—a hidden ingredient in almost every type of food out there from hamburgers to breads.  We were never told about the dangers of cross reactivity despite well-documented cases of children with peanut allergies who have died after eating soy, not peanuts.   The Mayo Clinic has warned about the dangers of soy for severely peanut-allergic people with asthma, yet most allergists and allergy information websites fail to warn parents of this danger.     We very much want to alert the many parents who are unaware of soy’s risks to children with peanut allergies and asthma.”

On February 22, the Weston A.. Price Foundation learned the sad news of the death of a nine year old girl who was allergic to peanuts but died after drinking soy milk:

“My cousin’s daughter just passed yesterday after having soy milk for the first time.  She was known to have peanut allergies and asthma.     My cousin watched what she ate but he was not aware of the relationship between the peanut allergy and soy.  She had an asthma attack and did not respond to treatment.  My cousin and his wife performed CPR; she was taken to a hospital in Baltimore then flown to DC Children’s. All of her systems failed and she died Tuesday morning.  She was the light in her father’s eyes. Her brother thought she hung the moon just for him; her mother is devastated.”

Hundreds of other mystery deaths may also have been caused by the soy-peanut connection.   Indeed, it’s a question that needs to be asked whenever we hear that someone with peanut allergies dies suddenly after eating a hamburger, a burrito or some other food that did not contain peanut ingredients.   The obvious question is, why so many reactions, and why now?

Soy is now widely acknowledged to be one of the top eight allergens, and many experts believe it will soon be in the top four.   Reasons for the rise include the widespread use of soy infant formula, growing numbers of vegetarians and others health-conscious individuals who substitute soy products for meat and/or dairy,  and the increased number of allergens found in genetically modified (GMO) soy.   The last appears to be particular important as the number of people diagnosed with soy allergies has increased by 50 percent since 1998, the first year that genetically modified soybeans entered our food supply.

The GMO issue may be the key to the increasingly number of severe soy-peanut cross-reactions.   As reported by Robyn O’Brien on the AllergyKids website:

“According to previously undisclosed research and the Peanut Genome Initiative, it appears that in the genetic engineering of soy, a soy allergen was created that is 41 percent identical to a known peanut allergen, ara h 3. This new allergen, now found in soy, is recognized by 44 percent of peanut allergic individuals.    Recent studies out of the University of London conducted by Gideon Lack support this undisclosed research and highlight the role that conventional soy (and soy formula) play in the development of the peanut allergy.  . .   In the United States, 90 percent of soy now contains these new proteins, chemicals and allergens.”

Why hasn’t this news gotten out?   Why do so many allergy support groups neglect to issue warnings about the soy-peanut connection?     Given the fact that soy ingredients are in more than 60 percent of processed or packaged foods and nearly 100 percent of fast foods, this is simply irresponsible.   Not surprisingly, the reason appears to be the usual principle of profits over people.    According to Robyn O’Brien of AllergyKids, “Leading pediatric allergists and researchers have been funded by the agrichemical corporation responsible for engineering these proteins, chemicals and toxins into soy.”

Will the Odwalla case bring this lifesaving information into the mainstream media?   As yet, the culprit hasn’t been identified as soy.   The likelihood is high, however that soy will soon be accused and proven guilty.   In the meantime, we can only hope, pray, and make a concerted grassroots effort to share this information with as many people as possible.

    A couple of questions.

    1. For those that are susceptible to a soy allergy reaction, does that apply to fermented soy products? In other words, is it ever the case that miso would be OK but soy additives would not?

    2. Has it ever been documented where the soy allergy reaction occurred due to foods from animals that were fed with soy?

  2. Health Nut says:

    I think it’s probably just best to stay away from both peanuts and soy. Neither are part of a healthy diet. Well, soy is okay as long as it is of the fermented variety.

  3. Alan, It depends . . . Some people have severe soy allergies, others less so. And some of the people are reacting specifically to the novel proteins in GMO soy. People who are allergic to peanuts should take the precaution of avoiding all soy, even minuscule amounts. And, yes, some people are reacting to eggs, dairy and meat from animals fed soy feeds.

    I have been aware of this connection for about 55 years. My Dad and his parents knew of this in the late 1920’s. My father had severe allergic reactions to all high protein vegetables. He must have had an astute physician when he was a baby in Vermont all those years ago! This awareness on their parts was probably one thing that led to my life long interest in food and nutrition.

    You are suffering but fear not I have been there too. There is life wiuotht nuts! I never ate anything that was not approved of by my mother when I left home I lost so much weight as I couldn’t eat wiuotht her approval. But I gradually learnt to do it very quickly (yes I know that doesn’t sound right) Make sure your friends are aware, take care soon you will do it. My friends are great at it now. If I’m going over they have nut free day.Stop washing your hands though or you could get reaction to all that soap! Get help for this obsession it will help with your fear.

    A person necessarily lend a hand to make critically articles I might state. That is the first time I frequented your web page and to this point? I surprised with the analysis you made to create this particular put up extraordinary. Wonderful job!

    On 9/13/12 my 6 year old daughter, who is highly allergic to both peanuts and treenuts, went into anaphylaxis after having a few sips of Shaklee’s Cinch Vanilla Soy Isolate Protein shake. Thank God this happened at home and we realized what was happening. The shake mix tested negative for peanut protein. My daughter never had a problem with soy before this incident. She now has a soy IgE of 73 and a peanut IgE of 433. She has since passed a soy milk challenge but we are avoiding soy w/ exception of soybean oil and soy lecithin. Would love to hear any other stories or input. It’s been 2.5 months. I am grateful that she is alive and well. I am also traumatized and scared to give her anything w/ legumes or unknown ingredients (natural Flavors).

  9. Colleen McIntyre says:

    I am currently working with Coke to change the warning label on Odwalla protein drinks. My son had a severe reaction to the drink. Is there a phone number of someone I can reach directly?
