New gluten challenge study aims to make 'Gluten-Free' labels safer

This completed study from Oslo University Hospital involved 33 adults with celiac disease who followed a strict gluten-free diet. Over five separate one-day challenges, participants consumed wheat gluten, barley gluten, hydrolyzed barley gluten, or a placebo. Researchers measured immune responses in the blood and gluten fragments in urine and stool to see which forms of gluten trigger reactions. The goal was to develop better analytical methods to assess the safety of partially hydrolyzed gluten in food products for celiac patients.
