Perhaps Mr. Kasarda, a List-member  who works for the USDA would be a
more credible poster. However, were you to check, I think the findings
are that "OATRIM" is used in meats, colas, and other formulated foods.
The Beta Glucans  are the specific derivative from "OATRIM" that has
been placed in ice tea, fruit juice , sports drinks, and even, wine. The
process was developed at USDA's Midwest Area Northern Regional research
center and is commercially supplied by ConAgra and Quaker Oats.

It is supposed to be a benefit to normal humans. How it acts on the
villa of those with Celiac Disease/Dermatitis Herpetiformis is not
something I would deign to presume. AMS
