Posts one through four have been about the early history of the dietary treatment for celiac disease. Some of you may be interested in learning more history while others of you would like to move on already! Before moving on to the […]

Remembering the children, especially “Mechie” who helped doctors identify gluten as the factor in wheat responsible for the deleterious effects of celiac disease

In Honor of Celiac Disease Awareness Month, Gluten Free Watchdog is writing a series of articles (the goal is one per day during the month of May) related to the gluten-free diet–currently the ONLY treatment for celiac disease.

“Based on the results of an investigation of a number of patients with coeliac disease, the harmful action of wheat flour was shown to be chiefly inherent to the gliadin fraction. —van de Kamer, Weijers, and Dicke. Acta Paediatrica. 1953;42:223-231

The Gluten-Free Diet is Born: Thank You Dr. Dicke!

In Honor of Celiac Disease Awareness Month, Gluten Free Watchdog is writing a series of articles (the goal is one per day during the month of May) related to the gluten-free diet–currently the ONLY treatment for celiac disease.

“We have learnt in the course of many years’ experience in the treatment of celiac disease that it makes a great difference to the patient what kind of starch-containing foodstuffs are included in the diet; in particular whether or not wheat is […]

Banana Baby: A former patient of Dr. Sidney Haas tells her story

In Honor of Celiac Disease Awareness Month, Gluten Free Watchdog is writing a series of articles (the goal is one per day during the month of May) related to the gluten-free diet–currently the ONLY treatment for celiac disease.

Long before gluten was identified as the culprit in celiac disease, a doctor by the name of Sidney Haas in New York City was treating pediatric patients using what came to be known as the “banana diet.” A former patient of Dr. […]

Early Dietary Treatment for Celiac Disease: The Banana Diet

In Honor of Celiac Disease Awareness Month, Gluten Free Watchdog will be posting a series of articles (the goal is one per day during the month of May) related to the gluten-free diet–currently the ONLY treatment for celiac disease.

The Early History of the Diet for Celiac Disease (excerpted from The Gluten-Free Nutrition Guide by Tricia Thompson, McGraw-Hill, 2008)

“The gluten-free diet has not always been the treatment of choice for celiac disease. Before the 1950s and the identification of wheat […]

Gluten Free Watchdog Position Statement on Consumer Use of the Nima Sensor to Test Food for Gluten

Bottom line:

At Gluten Free Watchdog we have been testing a wide variety of products with the Nima Sensor. It is very difficult to put the results of testing completed to date into proper context due to the lack of a published validation report on this device. One goal of our testing is to provide recommendations for consumer use of the Nima Sensor. This is proving to be impossible at this time. In the opinion of Gluten Free Watchdog the […]

What’s to blame for possible false positive “low gluten” test results using the Nima?

Bottom line: Gluten Free Watchdog has personally tested many products using the Nima Sensor. One of the issues slowly emerging is what appear to be false positives (e.g., defined by Gluten Free Watchdog as products testing “low gluten” when tested with the Nima but less than 1 ppm when tested with the R5 ELISA) when testing certain types of samples. The gluten-free foods (and products free of gluten-containing ingredients) testing “low gluten” using the Nima have similar ingredients and […]

Fermentation Growth Media for Yeast and Concerns about Residual Gluten

Gluten Free Watchdog recently received a question about the yeast used in a Crispin (Miller-Coors) hard cider certified gluten-free by GFCO. Neither GFCO nor Miller-Coors would disclose the growth medium used for the yeast.

Yeast testing: In an attempt to learn more about residual gluten protein in yeast grown on gluten-containing growth media Gluten Free Watchdog tested White Labs Pilsner Yeast cultured in a solution containing barley malt for gluten. This yeast is NOT labeled gluten-free. But, according to the […]

R5 ELISA Test Results for Gluten-Containing Products Testing “Low Gluten” & “High Gluten” Using the Nima Sensor

Bottom Line: Based on testing done to date by Gluten Free Watchdog, products testing “low gluten” using Nima tested from below the limit of detection of 1 ppm gluten up to 18,963 ppm gluten using the R5 ELISA. Barley flour also tested low gluten. Based on these results it is difficult to assess the meaning or understand the usefulness of a “low gluten” Nima reading.

Why did we test gluten-containing products: We tested a variety of gluten-containing products out of […]

Products testing low gluten using the Nima Sensor test less than 5 ppm using the R5 ELISA: False Positives?

Bottom Line: In some cases packaged food labeled gluten-free (or appearing to be free of gluten containing ingredients) testing “low gluten” using the Nima may test below the lower limit of quantification of 5 parts per million of gluten (and below the limit of detection of 1 ppm) using the fully validated R5 ELISA Mendez Method (Ridascreen Gliadin R7001).

Comparison Testing: Results comparing the Nima to the R5 ELISA included in this summary report are for the same product. In […]
