Fructans and ATIs impact digestive health in beer

The GLUTEN3S research group of the University of the Basque Country (EHU) has identified the presence of fructans and amylase/trypsin inhibitor (ATI) proteins in gluten-free beers made from barley, compounds that can cause digestive symptoms in sensitive individuals. Its content is comparable to that of traditional beers containing gluten, according to a study published in the Journal of Food Composition and Analysis.
