Yes it is.  So I try to buy block only, but still watch for it.

I believe it is also commonly used in pre-grated parmesan cheeses, like Kraft's.

Thank you so much! This is helpful, just to know. Over the years, I’ve seen the scope and understanding of the disease broaden. In some ways, I think it’s remarkable a doctor in Oregon way back then could diagnose a baby he’d never met so quickly. I wish I’d asked more questions!! 

Yes mostly found on RX pill capsules and store bought shredded cheese are the worst for me.

Yes, in the mid-20th century, including the 1950s, some doctors and researchers referred to celiac disease as a condition primarily affecting people of European, particularly Northern European, descent. The term "Anglo-Saxon disease" was sometimes used in medical literature and discussions to describe celiac disease, based on the observation that it appeared to be more prevalent among people of Anglo-Saxon ancestry compared to other populations. This terminology stemmed from early epidemiological studies suggesting that celiac disease was more common in individuals of Northern European descent, while being less frequently diagnosed in other ethnic groups. However, this was likely due to differences in genetic predisposition (such as the prevalence of HLA-DQ2 and HLA-DQ8 genes), dietary habits, and diagnostic awareness rather than an absolute racial or ethnic exclusivity. While the term "Anglo-Saxon disease" is outdated and no longer used, historical references to it can be found in older medical texts and discussions about the geographic and genetic distribution of celiac disease.
