Is Oat Fiber Gluten-Free?

Over the years many consumers have asked me about the “safety” of oat fiber for people with gluten related disorders and whether this ingredient is likely to be contaminated with gluten-containing grains.

Ten years ago we did not have oats that were specially produced and processed to be gluten-free. Today, thanks to the pioneering efforts of Cream Hill Estates, Avena Foods, Great Northern Growers/Montana Gluten-Free, and Gluten-Free Harvest specially produced and processed gluten-free oats and oat […]

Gluten-Free Foods Still Contain Barley Malt

Despite having a gluten-free labeling rule in place, there are manufacturers who still believe that if they test their final food product for gluten using the sandwich R5 ELISA and it tests below 20 parts per million of gluten then they can label the product gluten-free, regardless of ingredients.
