3 Reasons Food Allergies Are on the Rise

My partner recently saw an ear, nose and throat doctor. He was looking for an explanation for the chronic sinus issues that have lingered for most of his adult life. In addition to a CT scan, and a DIY nasal rinse, the doctor requested allergy testing. To our surprise, the results indicated significant intolerance for wheat, eggs, peanuts, dairy and brewer’s yeast. I’ve got another friend who can’t eat Stevia without breaking out in hives, and yet another who treats gluten like the plague.

It seems like food allergies have moved from the realm of little kids into the mainstream, and it’s not all a weird diet bandwagon. Research confirms that food allergies are on the rise, and are among the leading chronic illnesses in the United States.

This change occurred in my fairly short lifetime. When I was a kid, my parents never thought about food allergies, but now, they’re splattered across the top of every parenting and healthy living blog you can find. So what’s going on here? What’s changed in the last 50 to 100 years to make an entire society react to food like they would to a bee sting? Doctors and scientists tasked with unraveling the food allergy mystery have identified three main theories.


It’s well known that allergic diseases tend to run in families, and science agrees that food allergies are no different. If your mother can’t tolerate dairy, or your grandfather can’t eat peanuts, it’s more likely that you will develop similar sensitivities. While heredity is an easy answer for some, it simply can’t account for food allergies’ transformation from a rare condition to a commonplace illness. Scientists have resorted to looking at changes in the food itself: how it’s grown, what it contains, and how it’s packaged. As Robyn O’Brien asks in an article called The Hidden Truth about Peanuts: From Food Allergies to Farm Practices, ”Are we allergic to food? or what’s been done to it?” Which leads us to…


It was back in 1996 that genetically-modified organisms began making their way into the food supply. Eighteen years might seem like a long time, but it’s just a flash in the pan when it comes to determining the effect of GMO consumption on human health. That’s why regulatory bodies like the U.S. Food and Drug Administration continue to insist that GMOs are safe, even though they know good and well that it could be another 18 years before we’re able to see their full impact. Still, there is compelling evidence to suggest that genetically modified crops are positively linked to food allergies. Especially when you consider that some of the most common genetically engineered foods (soy, corn, milk, peanuts, yeast) are also listed among the most common food allergies. That doesn’t even begin to address all the chemical pesticides and fertilizers we’re spraying on all food, genetically modified or not.

An Overly-Sanitized Environment

This one goes out to all the germaphobes carrying hand sanitizer in their back pocket. Or the clean-freak moms wiping down every toy with Lysol. Your obsession with killing germs and bacteria could be aiding the rise of food allergies. Referred to as the ‘hygiene hypothesis’ this popular premise suggests that “the overly sanitized state of our modern environment is upsetting the normal development of the immune system, leading to a possible overproduction of specific allergy-causing antibodies,” writes Mireille Schwartz, the founder and executive director of the Bay Area Allergy Advisory Board. Never exposing yourself or your loved ones to germs may seem like a good way to avoid illness, but it’s likely achieving the exact opposite. Living in perfectly sealed, sanitized, air conditioned environments has likely weakened our body’s ability to vanquish invaders. “Because of this lack of opportunity, the immune system becomes prone to respond by reacting to otherwise harmless substances — in other words, by developing allergies,” continues Schwartz.

Well said Luvenia V.
I already eat a lot of raw milk, and I'm adding horseradish to my diet this year after finally finding some in a Amish store. I would drink raw milk as well if I can find a local herd share as that is the only way at least in Ohio without raising the animals yourself.

We need the government to get out of our lives, stop telling us what we can or can not eat or what products to buy. Bring back respect for the Constitution with it's original intent and return our liberties. And if our elected leaders would finally sober up and deal with their debt addiction before we go over the cliff that would be great.

Food allergens and their cause remains a mystery, but is not related to GMO. It is more linked with over cleanliness, things that happen within the first few months of birth. Some tests show artificial sweeteners and over use of fat free milk plays a role with the lack of building certain digestive proteins, bacteria's. Artificial sweeteners distupt proper development during pregnancy, low fat milk lacks critical bacteria's needed for some foods.

Our obsession of cleanness make germs stronger, and the immune system has not to fight so is like naughty boy who bangs piano.

Guess it is very complicated! Personally I believe GMO's have some responsibility. That and overuse of extra gluten being added to breads and other items. DNA does play a part as well.
Thanks for the information.

Could be the foods we were weaned on our bodies adapt to. Changes later on aren't accepted very well. Might be immune to some chemicals and not to newer ones.

When I read the title I was afraid it would be full of BS but it was spot on. We are sicker than we have been in a LONG time and it is because we are destroying our system. The very idea that we use so many Antibiotics by prescription, in our soap and in my meat is beyond bad for us. The food we eat has been processed to the point that we eat MORE because our body tells us we are not getting what we need from the food and the food we eat have so much poison in it we are literally slowly killing ourselves and our family.

In MY opinion it would help if you find RAW HONEY made within 50 miles of where you live and eat some everyday because it will help with your allergies and your immune system. If you really want to help yourself try some raw goat’s milk. Sadly that means in most states you will have to buy a goat and milk it yourself because they are telling us raw milk is worse than the poison in the food they approve.
