Gluten Free Food But Says Less Than 20 Ppm Gluten? What Does That Mean?
0

9 posts in this topic

I was diagnosed with celiac disease in late February 2012 after a positive biopsy. The symptoms got better at first then returned. So next step I cut out lactose and soy, still having symptoms. This weekend I was eating blue diamond crackers which were label gluten free but noticed on the box in very small print, tested to contain less than 20 ppm of gluten. So this got me wondering if the reason I am still having symptoms is because some of the labeled "gluten free" items I have eaten are not in fact truly gluten free. For the most part I have been avoiding any processed foods but with my work schedule it is a lot easier to pack lunch that does not have to be kept in the frig and snacks that are labeled gluten free like these crackers, rice cakes, etc. The processed gluten free labeled foods are a lot easier to take for lunch and snacks on work days.

So I am wondering if I am possibly still experiencing symptoms because I am getting gluten from these foods.

Any thoughts?

Yes, it's possible you are reacting. Not everyone tolerates the traces of gluten in grain-based foods. The proposed FDA standard is <20 ppm, which is why Blue Diamond and many other brands label gluten-free at <20 ppm. Even great GFCO certified brands like Udi's are only guaranteeing <10 ppm.

It's also possible you are reacting to all dairy rather than just lactose. There are a fair number of us who are casein sensitive. Casein sensitivity is probably more common than being unable to tolerate <20 ppm foods.

The easiest way to check (and I know it's a pain because I eat this way) is to get rid of all processed foods for a bit and only eat food you cooked from naturally gluten-free food. I carry a 6-pack sized, soft sided cooler with an ice pack to work every day. It wasn't expensive at all and it works well. Using a cooler makes easy to be able to bring foods that need to be kept cold like dinner leftovers, hard-boiled eggs, cheese, or sliced veggies.

A food which contains absolutely no gluten whatsoever will test as less than 20 ppm. Don't assume that the test sensitivity has anything to do with the actual content. Testing can not prove zero, and the more sensitive the test, the more it costs to do. Many manufacturers test at 20 ppm, as it seems to be a reasonable compromise. The primary reason for the testing is to detect accidental contamination.

True, but the threshold of the R5 elisa, the most common commercial gluten test, is <3 ppm. Udi's, Kinnikinick, and anyone GFCO certified is using a cutoff of <10 ppm. IMO the <20 ppm proposal in the FDA has nothing to do with safety for people with celiac or test limitations and everything to do with food conglomerate lobbying.

But that's neither here nor there. We have had board members who didn't recover until they went to a diet that consists of only naturally gluten-free foods. Marku Makki has mentioned running across people who were similarly sensitive in his peer-reviewed research.

Thank you for the information. I am going to try an all natural gluten free diet and also eliminate Casein and see what happens.

Good luck! Be sure you're off oats as well. Some people react to oats as if they were a gluten grain. There's recent research suggesting corn can be an issue for some folks as well.

Thank you again. Last night I worked on a grocery list of naturally gluten free foods and worked out some menus for breakfast, lunch and dinner. Today after work going to the grocery store and stocking up. I still need to double check my vitamin supplements and medications, I know they are gluten free but going to check for soy and other possible triggers.

I am one of the people on this board who did not get all the way better until I stopped eating most processed foods. I have even had problems with packaged naturally gluten free items. I was fortunate to have a GI doctor who was familiar with celiacs who react to very low levels of cc, so I found out about it from him. At that time, almost 5 years ago, there was very little information out there about it. This forum now has a super sensitive section which deals with that condition.

Thank you for the information, I will check out the super sensitive section.

    • What's an " iodine test"?  Haven't heard doctors doing that to diagnose DH.
    • Hello! I've just been given my blood results and told they are highly suggestive of coeliacs but will have to wait till next month to see the gastroenterologist and who knows how much longer for a biopsy. My igA, igG and tissuetrans igA were all over 250 and tissuetrans igG was the only one that was normal. These results don't mean much to me yet but I'm told they are very high. I'm now quite fearful of how much damage I've gone to myself. I've had stomach problems for 25 years (just turned 40) and have often steered clear of too much bread and pasta for how bloated it made me feel but the symptoms were always vague and inconsistent so I kept eating. I had a couple of boats of gastro in the past few months (thanks kids) which I took a lot longer than normal to recover from which looking back may have been related. Then last Friday I had a blowout with wine, cheese, crackers, pizza and chocolate cake. I'm sure I've probably had blowouts like that before but I have never felt so sick before and am still slowly recovering. This is what finally prompted me to go back to my GP after being fobbed off so many times over the years. So I guess my question and my concern is whether there is still  chance of a false positive with levels like this? I worry what else it might be if not coeliac. I'm also worried that I may have done so much damage to myself that I will have several disorders going on! I'm also still recovering from last Friday and wondering when I'm going to feel better. I've stayed off gluten and dairy since my blood result a couple of days ago but feel like I'm allergic to food in general.  Thankyou!!    
    • Here's what the Klondike Bar makers say on the FAQ page of their website (August 2016): Are your products gluten free? Nope. They are not. We have not validated for gluten free. We do not operate allergen-free manufacturing sites, however we do have allergen management programs in all our facilities. The intent of these programs is to avoid unintentional cross-contamination of allergens between products. Our product labels adhere to the FDA’s strict regulations regarding declaration of ingredients and allergens. We do not use the terms “Natural” or “Artificial Flavorings” to hide the existence of any allergens. RECIPES CAN CHANGE. We strongly recommend that allergic consumers refer to ingredient declarations EVERY TIME they purchase processed foods.
    • I tried the iodine test but couldn't leave it on very long because it itched too much. I left it on maybe 30 minutes lol. Did anyone try it and have the same response??
    • Had my scope today. Dr said my esophagus is damaged and stomach inflamed. Waiting on biopsy results. Taking protonic and flagyl and he said to go ahead and try cutting gluten out to see if that helps. Thanks for the feedback everyone!
