Why Are Food Allergies on the Rise Part 1 GMOs
If youve worked with kids lately, or if youre a new parent yourself, then Im sure you know all about this epidemic of food allergies. According to a 2011 study, 8% of American children under 18 have at least one food allergy, and that is up from 4% in 2009 (1). Peanut allergies in particular have been on the rise. In one Midwestern county, the prevalence of peanut allergies in children tripled between 1999 and 2007 (2). But you dont need numbers to realize its a problem. Just spend a day in a school cafeteria. Or a summer camp. Just enter an elementary school classroom at all and youll hear about it; the concern is clearly growing. Dairy may be the most common allergy, and it seems kids can have a reaction just looking at a peanut, but there are others to worry about as well, including wheat, eggs, soy, tree nuts, fish, and shellfish.
But it wasnt always this way. When I was a youngster, I dont recall ever hearing about another kid having a food allergy. Maybe the most I ever heard was that a classmate was lactose intolerant. But there was no mention of peanuts. Nobody had a wheat allergy. Nobody went into anaphylactic shock at the mercy of a pistachio. So what gives?? Why are food allergies exploding?
Well, sadly I dont think we know the answer to that question. Much has changed in the food and health world over the past few decades, so we have many likely culprits. Over these next few posts, Ill be exploring the options, in a sort of thinking-out-loud fashion. Excuse me if what follows turns into an incoherent mess.
Genetically Modified Organisms
This seems to be a hot topic right now. Genetically modified organisms (GMOs) are plants or animals that are created through gene splicing techniques. This merges the DNA from different species, creating a new variation of a species that wouldnt be possible through traditional crossbreeding. Example. Say biotech giant Monsanto finds a bacteria that naturally resists an herbicide like Round Up. (They did.) Then they isolate the gene that allows that bacteria to resist the pesticide, and they splice it into corn. (Again, they did.) Now they have a genetically modified strain of corn that resists Round Up. Lets call it Round-Up Ready corn. Now we can grow mass quantities of corn and spray mass quantities of Round-Up on it to kill those pesky things like weeds and bugs, while leaving the corn unaffected. Yes, believe it or not, true story.
The following foods have been approved to be genetically modified: alfalfa, canola, corn, cottonseed, papaya, soy, sugar beets, and green/yellow summer squash (3). You may say, well, thats only 8 foods, thats not that bad. But canola, corn, cottonseed, soy, and sugar beets are nearly ALWAYS genetically modified, and theyre found in nearly ALL processed food. Youd be hard-pressed to find anything in a box or a bag that doesnt contain at least one of these, just look next time youre shopping.
So how do you know if what youre eating contains GMO ingredients? Its not easy. Companies arent required by the FDA to label a product as GMO, contrary to the wishes of the American people. So if you want to know, youve gotta be a detective and read the ingredient list. Or, if you want to make it easier on yourself, you can buy organic. Any food certified organic is free of GMOs. In addition, apparently, GMO fruits and veggies must be labeled with a 5-digit code beginning with an 8, rather than the conventional 4-digit code. Ive yet to see one of these for sale, but no doubt its coming.
But the worst part... we dont even know if eating this stuff is safe. There are some people claiming that the studies have been done and theyve been swept under the rug to hide the incriminating evidence (4). Who knows if theres any truth to that. Then there was this recent study from France, showing that rats eating GMO corn developed breast cancer at a far greater rate than control rats fed non-GMO corn (5). And of course, biotech companies like Monsanto swear by their safety. Its no different than regular corn, they say.
But the fact remains... GMO foods are a science experiment. Nobody in the history of the earth has consumed anything like this, and wed be giving ourselves too much credit as scientists to say "its just the same as corn". Were not even close to understanding all the intricacies of how the human body works, let alone how a brand new franken-food is going to interact with said body. I dont think we know how much we dont know, which is why its always a good idea to default to evolutionary biology... Were designed to eat plants and animals; were not designed to eat herbicide and pesticide resistant corn. We are the subject of a science experiment, and nobody knows how its going to turn out.
But are GMOs causing food allergies?
Is it possible that the recent spike in food allergies has a link to these genetically modified foods? It sure is. The timing works perfectly... GMO foods as we know them today burst onto the scene in the late 1990s (6). Thats just enough time for families to start eating them and start popping out kids with food allergies. Theres no way to know, as of yet, just what GMOs are doing to our health. But given all that Ive said so far, it does seem a bit fishy doesnt it? Yes, fishy indeed. One thing is for sure... if I were to have kids today, GMOs would be one of the first things Id watch out for.
What are your thoughts, reader(s)? Id love to hear your opinion on GMOs.
And stay tuned for the rest of the series. Ill be discussing all kinds of fun stuff, like antibiotics, medications, and dwarf wheat. Come on back!
