Anyone have a corn allergy too? My son tested positive for corn allergy on a RAST test, but pulling it out of his diet and putting it back in made no difference in the itchiness problem we are investigating. However, today he got a bit itchy after eating some Smarties (the American candy that is tiny pastel sugar circles). The only ingredient,besides sugar and coloring, was corn syrup which we never eliminated from his diet since we were told it would not cause a reaction. I would appreciate any thoughts on corn allergy. Thanks

Hello, My son tested positive (skin test) to corn the first time when he was about 15 months old even though he had eaten products which contained corn prior to testing. We did eliminate the corn until we had him tested again (we changed doctors) about 4 months later and he tested negative so we reintroduced corn to his diet. He was itchy before and after the corn incident. He has eczema and is allergic to peanuts and eggs. He was also allergic to wheat (not anymore).

Not many people are allergic to corn, it's a tough allergy to deal with. There is corn in almost everything.

Hi! My son is PA and corn allergic (with many others, too). We had no idea about his corn allergy before he tested positive 2 years ago. After we eliminated corn, if Logan got any hidden corn he would have a complete emotional breakdown exactly 3 hours later. Also, before eliminating corn he had loose, bulky, foul-smelling stools with other symptoms of malabsorption and eczema. Both have cleared up. Now when he accidentally gets corn he does not have the emotional reaction so we reintroduced it a while back. It took about 3 days before he started showing digestive sypmtoms and then about another 3 days for them to clear up after we took the corn back out.

In August we had his skin testing re-done and the corn welp got so big they had to wipe it off after only five minutes. We had his levels checked by CAP RAST for all the foods we're avoiding and I hope to have those results next week - I doubt he's outgrowing the corn allergy, but there's always hope!

Delphi has an avoiding corn forum and I've read a lot of people on there who have mental/emotional type reactions to corn so I wonder if corn reactions are sometimes hard to recognize in a young child...

Wow, this is incredible! I have a 5 year old daughter that is allergic (but not severely to any) to about 20 foods. Corn is one of the worst ones. She has been having real emotional outbursts occasionally and has eczema really bad, now I'm wondering if it could be from corn. The allergist told me that I just needed to reduce the amount of foods with the offending allergens but that they did not have to be eliminated. (That included peanuts... he just recently gave me an epi pen for her after I insisted- I have a 6 year old pa son also).

Thanks again for the info!

I'm curious to know more about the emotional outbursts your children display when exposed to corn. My son's allergies always seem to manifest themselves in his behavior. We are now in the process of trying to rule out (or in) ADHD. He also has sensory integration problems. He was allergic to corn as a baby (he's now 8), but I was told he outgrew that allergy. After reading your posts, I'm thinking maybe I should try eliminating that from his diet and see what happens. Corn is a hard one--it's in EVERYTHING!!!

It's actually pretty difficult to describe Logan's emotional breakdowns from corn. Logan is normally very mellow and easy-going but when he's having a "corn fit" he cries/screams uncontrollably, hates me and everyone else, thinks everyone hates him, etc. The tiniest thing will set him off and he won't be able to stop himself. It really scares him and us.

I've read of parents whose children were mis-diagnosed ADHD and even autistic before their corn allergy was diagnosed.

It is really hard (if not impossible) to completely avoid all corn products, but it might be worth giving it a shot for a month or so just to see if it helps.

Rebekah, I am interested in your corn allergy knowledge. My 9 month old has already tested positive to peanuts and egg yolks, which we now completely avoid. But she is still constantly gassy, has alternating firm and mushy stools, and doesn't sleep well. Does any of this sound like your child's corn reactions? I have been keeping food logs for DD and myself (she is still nursing) and nothing in her diet stood out consistently, but I realized after reading your post that hidden corn products in my diet might be consistent enough to be causing her problems if she is allergic. Any info. or website references you have would be much appreciated! Thanks! Rebecca [img][/img]

Hi Rebecca,

So sorry it has taken me so long to get back online and respond to you! Yes, your daughter could have a corn allergy or it could be soy or wheat or dairy - those things are all very prevalent in our diets and are not always obvious.

Corn is in almost every pre-packaged food and does NOT have to be labeled. It is also used in packaging and processing so even if you call you might not find out about those sources. Every Kimberly Clark product has corn in it (Huggies, Kleenex, Viva paper towels, etc). Most domestic cheese wrappers are dusted with corn starch. Libby's dusts the inside of their cans with corn starch so even though the fruit inside the can is okay it is contaminated. Most frozen vegetables are processed with corn. Words on a label that may indicate the presence of corn:

starch or modified food starch(unless the type is specified) dextrose malt (unless the type is specified) vegetable protein (unless the veg. is specified) maltodextrin fructose and most anything else ending in -ose salt (iodized salt uses dextrose as a stabilizer) natural flavors monosodium glutamate vanillin xanthan gum vinegar powdered sugar baking powder Those are just the ones I can think of off the top of my head. The best information on avoiding corn I've found has been at [url=""][/url] and [url=""][/url]

I've used these sites as starting points and then through trial and error found what Logan can tolerate.

If you have any questions about specific food I let Logan eat feel free to ask!

Rebekah, Thank you so much for the info! Wow! It is unbelievable what they will sneak allergens into! Kleenex?!?! I've been wiping her nose with them all week! (She's got a cold. [img][/img]) She was tested for wheat, milk and soy at the same time as her egg & peanut test, so I don't think any of those are the culprits. I started a trial no-corn diet this week, but haven't seen any change yet. I thought I was doing really well; I caught the vanilla & baking powder, but unfortunately, it sounds like I may not be totally clear of corn yet. [img][/img] Those websites were very informative. Do you know if corn is an allergy that is commonly outgrown? Her allergist told me that they usually outgrow milk and egg allergies by age 5. Thanks again for the info. Wish me luck! I am desperately craving soda pop; I hope I can stick out this diet for another week! [img][/img] Rebecca P.S. Do you let your son eat things baked with regular sugar? One of those websites said that it sometimes contained corn starch. Are there any natural sweeteners (not Equal, etc.) that are ok to cook with? I've got a real sweet tooth!!

Your daughter sounds as an identical twin to my youngest son. He experienced the same symptoms you are referring to but he has no food allergies. He is however extremely lactose intolerance. It took me several months to realize this as I was also nursing. I remember distinctly being in the hospital with him and I was walking up and down the halls trying to console this fretful infant. Later I recalled that my husband brought a milkshake for me to drink. You may want to try eliminating dairy after you attempt the corn ellimination.

NaomiR, Your message interested me greatly, since I asked my daughter's pediatrician about lactose intolerance and she said that breastmilk always contained lactose, whether the mother was consuming cow's milk or not. . . But one thing I have learned through this food allergy business is that everyone has a different opinion on things, even doctors. I think we have to just see what works for us; if avoiding corn doesn't improve her symptoms, I will definitely try eliminating dairy. Thanks for the suggestion. I must say that it is so encouraging to correspond with all of you who are going through similar struggles to my own. Sometimes I just feel like having a pity party for myself when I start missing all of the foods I can no longer enjoy and the convenience of fast food, etc., not to mention the stress of keeping DD safe. It is comforting to know we're not alone in this.

Yes, I let Logan have regular granulated sugar (pure cane) - powdered sugar is the one with corn starch in it and sometimes granulated sugar that does not say "pure" is a mix of cane sugar and corn sugars. Pure vanilla is okay, it's vanillin (artificial vanilla flavor) that you have to watch out for. I personally don't worry about what type of alcohol the pure vanilla extract uses. I also allow Logan to have caramel color. We let Logan drink diet sodas because the artificial sweetners in those don't have corn starch in them. The artificial sweetners in powder form (packets) have corn products to prevent them from getting hard and clumpy. Also you can order Dr. Pepper from the Dublin, TX plant. They make it the old fashioned way with pure sugar instead of corn syrup - it tastes wonderful, too! In the spring during Passover they make coke and many other products that are corn free - just look for the label Kosher for Passover. During Passover corn is not supposed to be eaten. Regular Kosher food is allowed to have corn, though.

I *believe* most food allergies are usually outgrown except for peanuts, tree nuts, fish and shellfish but of course that doesn't mean it always happens that way. We're still keepinig our fingers crossed for Logan (he's 5). I believe most adults who have problems with corn have an intolerance (like with lactose) to corn and not a true allergy. That doesn't mean their symptoms are any less severe though.

Good luck on your corn elimination diet! Hopefully you'll be able to figure out something soon!


P.S. Logan really enjoys the Gerber Graduates turkey sticks. They seem to be corn free and have a pretty soft texture that your dd could probably handle. The chicken sticks are a bit firmer than the turkey ones and Logan doesn't like them as well. He also enjoys Breyers All Natural Vanilla ice cream (might help your sweet tooth) [img][/img] .
