Quinoa and Possible Barley Contamination

The Chicago Rabbinical Council (CRC) recently posted an alert on their website concerning quinoa and its suitability for Passover http://www.crcweb.org/alerts.php. This alert has implications beyond the Jewish community to include those with celiac disease. I had the pleasure of speaking with a Rabbi from the CRC to confirm this information. For the past several years quinoa in general was considered suitable for Passover*. This is no longer the case. After thoroughly investigating the issue, several concerns have been raised by the...

Gluten Peptides in Human Breast Milk: Implications for Cow’s Milk?

Bottom line: A very small number of published studies report finding peptides in exceedingly small amounts (measured in parts per billion) in human breast milk. If dairy cows are fed wheat, barley, and rye grain (not a common occurrence from what I've been told) and if they have the same difficulty digesting (breaking down) gluten protein as humans, it is reasonable to wonder if gluten peptides may be found in cow's milk too. However, based on testing, no significant amounts...

Naturally Gluten-Free Grains and Gluten Contamination

We all know that if we eat oats they should be labeled gluten-free. We know this because it is well established that “regular” commercial oats are very likely contaminated with gluten. If you are interested in testing data it is available here. What is less well established is whether other naturally gluten-free grains NOT labeled gluten-free like millet, sorghum, and buckwheat are likely contaminated too. In 2010, Thomas Grace, Anne Lee and I published the study, “Gluten contamination of grains, seeds, and...
