Oat Beverages & Celiac Disease: Why We Are a Bit Concerned

Oat Beverages & Celiac Disease: Why We Are a Bit Concerned

Bottom line: If you drink oat-based beverages, please choose products you trust made using gluten-free oats. Gluten in liquids adds up very quickly.

Background: The part per million level of a product is obviously important BUT it doesn’t tell the whole story. The amount of gluten ingested depends on BOTH the ppm level AND the weight amount of product eaten. Each 1.0 ounce/28.35 gram amount of product ingested at the 20-ppm level provides about 0.57 milligrams of gluten.

What does this mean in the real world? Gluten Free Watchdog recently tested an oat “milk” NOT labeled gluten-free. It contained a level of gluten of approximately 12 ppm. This seems fine, right? BUT have you considered how many ounces by weight you drink of various beverages?

Gluten in liquids adds up quickly because of the weight amount consumed. The 8-ounce (by weight) glass of oat “milk” in the photo testing at a 12 ppm level of gluten contains about 2.7 milligrams of gluten.

How much would you have to consume of other products to ingest approximately 2.7 milligrams of gluten at a 12-ppm level: (Please note: The following products have NOT been tested)

The entire 8-ounce box of cookies!

The entire 8-ounce box of pasta!

8 (EIGHT) 1-ounce bottles of this herb!

To reiterate: If you drink oat-based beverages, please choose products you trust made using gluten-free oats. Gluten in liquids adds up very quickly.

    It has never made sense to me that the gluten content of food is expressed in ppm, but other things (e,g., fat or sodium or calcium) are expressed in grams or milligrams per serving.

    It would be helpful if this article included the oat milks that have been tested by y’all to be safe 🙂

      We have only just started testing oat “milks.” The recommendation at this time is to avoid oat beverages not labeled gluten-free.

    Thank you for explaining the ppm to mg difference.
