Are Oats Gluten Free?

Check the Label

May be safe if certified gluten-free.

Pure oats contain avenin, a protein different from gluten. Most coeliac sufferers tolerate pure, certified GF oats. However, cross-contamination during growing and processing is the real risk.

Coeliac Disease

Start with small amounts and monitor closely. Use certified GF oats only from reputable suppliers.

Gluten Sensitivity (NCGS)

Safe for most NCGS sufferers if pure. Avenin sensitivity is rare.

Why Do Oats Sometimes Contain Gluten?

Avenin is structurally different from gliadin/glutenin. About 1-3% of coeliac patients react to avenin itself. The main issue is contamination from wheat/barley grown nearby.

Australia vs United States

Australia (FSANZ)

FSANZ allows GF oats if certified and <20 ppm gluten.

United States (FDA)
