Are Gluten Traces in GF Foods a Risk for Celiacs?

A very interesting article in the January issue of the American Journal of Clinical Nutrition asks a compelling question in its very title:

Might gluten traces in wheat substitutes pose a risk in patients with celiac disease?

The study evaluated gluten-free foods from four European countries where Codex Alimentarius guidelines are followed for the labeling of gluten-free foods: fewer than 20 parts per million of detectable gluten in order to be called gluten-free, and 21-100 ppm gluten to be called “very low gluten.”

All of the samples were analyzed using the R5 ELISA, and while we agree that using only one test for gluten is not sufficient, those of us who follow a gluten-free diet were still relieved to learn that the foods tested quite safely within the parameters of the study.

Differing Opinions on Gluten Analysis Research

Recently an article was published in the American Journal of Nutrition detailing the gluten content of a variety of different gluten-free foods available for sale across several European countries.

Reassuringly, the study found that the overwhelming majority of products available were not only below the Codex Alimentarius guidelines of 20ppm or less detectable gluten, but had no detectable gluten at all.

However, the study itself only included one type of analysis: the R5 Sandwich ELISA. While this is no doubt the most popular analysis for gluten detection, it isn’t the only one. The R5 antibody does not necessarily tie toxicity to a positive result (detection of gluten), and so the possibility exists that a food testing negative for gluten with this method could in fact still be toxic for people with celiac disease.

For more, read the editorial (as a PDF and published in the American Journal of Clinical Nutrition) about gluten-free food and its safety for celiac patients.

A Long Overdue Update!

Oh goodness. Happy 2013 everyone!

It’s been quite some time since we’ve updated here, and it’s hard to believe we’re already in 2013. There are some exciting things underway for GlutenTox this year, and we’ll be sure to keep you posted about those as they arise.

For now, though, we want to shed a little bit of extra light on one small area of the gluten-free world: testing surfaces for gluten. Those of you who use GlutenTox Home generally test foods or cosmetics or beverages for gluten — although you certainly can use the test to detect gluten contamination on countertops or mixing bowls or other hard surfaces! If you aren’t sure how to use GlutenTox Home to check for invisible traces of gluten on surfaces, just check out our FAQ. Read More…

Can GlutenTox Detect Gluten in Highly Acidic Foods (like Lemons)?

We often get asked whether GlutenTox Home can accurately detect gluten in highly acidic items like lemon juice. The answer in a nutshell? It sure can!

Traditionally items with extreme pH balances have been tricky for gluten test kits, but GlutenTox contains a dilution solution formulated with a special pH stabilizer. To prove it, the team at Biomedal’s ISO-certified gluten analysis lab prepared three very special batches of lemon juice.

The first sample was the control, a basic bottle of lemon juice from the local supermarket. They happened to use Prima brand, which contains: lemon juice from concentrate (water, concentrated lemon juice), natural flavors, citric acid, sodium benzoate, sodium metabisulfite and sodium sulfite. As it happens, the pH value of this lemon juice is 1.64 — not only is it very, very acidic, it’s most acidic than most plain lemons!

GlutenTox Tests Margarine for Contaminating Gluten

If you live with gluten-full people, you have probably seen your fair share of contaminating gluten crumbs. Is it the jam? Peanut Butter? Margarine? If your housemates or loved ones double dipped their knives in the spread, chances are, at least a crumb or two settled in. Sometimes you may notice the contamination immediately, but other times it may be hard to identify.

We’re happy to share that GlutenTox Home can detect contamination in spreads, even if it’s just a single crumb in margarine!

Our friends at Biomedal tested margarine with varying amounts of contamination for gluten.  They tested three samples of contaminated margarine: one with just 1 crumb, one with 2 crumbs, and one with several little crumbs.

The results? GlutenTox Home tested positive for all three samples at 5ppm! Just as a control, a clean margarine sample was tested and found negative.

 Because pure fat does not itself contain gluten, sometimes special steps are needed to ensure any isolated bits of gluten are found.  However, this test easily detected even just a few breadcrumbs in the margarine. The fat content did not interfere in the detection of gluten at the levels we studied.

Now, you can be sure that your gluten-free toast with margarine is as safe as you thought it was!

Meet Emport: Introducing Our Intern, Ruthie

Hi! My name is Ruthie and I’ve been working at Emport for a few weeks now. I just started my senior year at Carnegie Mellon University where I’m studying Decision Science (Economics & Psychology) and Global Studies. Here at Emport, I have been working as the business development and marketing intern.

I’m happy to join the Emport team this semester and am looking forward to learning more about the gluten sensitive community. Having grown up alongside close friends and family members who struggled with celiac disease, I am interested in learning how we can help make gluten-free lifestyles easier to maintain.

I am originally from New York, but have enjoyed calling Pittsburgh my home for the past few years. When I’m not at the Emport LLC office or on campus, I’m taking advantage of the many museums, restaurants, and concerts that Pittsburgh has to offer or experimenting with new recipes in my kitchen. My favorite new recipe is actually one for gluten-free baked macaroni and cheese!

Stuffed Pepper Tests Lemon Rind for Residual Gluten

There are so many places that gluten can hide! Sometimes things once thought to be off-limits (like the gluten from envelopes and stamps) can turn out to be safe. Other times, something that we always considered safe can wind up being a source of contamination.

Intrepid blogger Heather over at Stuffed Pepper had some questions about the wax used to coat produce (lemons, specifically). Conveniently, we’d sent her some GlutenTox Home tests to try out – and to her lemon zester she went!

To read more about her test results — and the fascinating things she learned about potential allergens in produce wax — visit Stuffed Pepper.
