Pasta Straws Can Be a Problem for People with Celiac Disease

Please be aware that corn is increasingly viewed as a gluten-free "safe" eco-conscious packaging ingredient but that that a significant proportion of celiacs may react to corn as if to wheat and may not themselves be aware of this (example:  https://gut.bmj.com/content/54/6/769.full )

I'm not sure the linked article is talking about a cross reaction to corn in celiacs because it specifies that this was a rectal phenomenon rather than small bowel. Celaic disease affects the small bowel, not the rectum. Besides, who eats their packaging material?

We all eat our packaging material, willing or not, and corn does not have to appear on food labels.  Meat is dipped in a corn bath before reaching grocery stores.  Dry goods have corn maltodextrin added to reduce clumping.  The excipient (non-active ingredient) packed inside any pill vitamins and medicines you take is cornstarch.  New coatings to keep produce fresh are being developed that are corn-based, and current waxes used sometimes contain corn.

Since the one study did not seem pertinent to you, some others may help.  

The first link is layperson-friendly and links out to the research items it cites: https://www.glutenfreesociety.org/gluten-in-corn-can-damage-celiacs/ 

I've included an excerpt from the second:

https://pubmed.ncbi.nlm.nih.gov/24152750/ 

(excerpt:)  In some celiac disease patients, as a rare event, peptides from maize prolamins could induce a celiac-like immune response by similar or alternative pathogenic mechanisms to those used by wheat gluten peptides. This is supported by several shared features between wheat and maize prolamins and by some experimental results. Given that gluten peptides induce an immune response of the intestinal mucosa both in vivo and in vitro, peptides from maize prolamins could also be tested to determine whether they also induce a cellular immune response. Hypothetically, maize prolamins could be harmful for a very limited subgroup of celiac disease patients, especially those that are non-responsive, and if it is confirmed, they should follow, in addition to a gluten-free, a maize-free diet.

So, by "packaging materials" you mean other than shipping boxes and cushioning material. But that's how I took it. Corn is one of many food substances that can mimic gluten for "some" celiacs such as oats, dairy, meat glue, etc.

I'm not sure if any of these comments are relevant to this article, are they?
