Research from the Leibniz Institute has found that standard antibody-based tests do not always identify certain gluten residues in barley beers, leading to potential health risks for individuals with celiac disease.
Some beers labeled as 'gluten-free' may still harbor small amounts of gluten, which could trigger adverse reactions in sensitive individuals.
These findings underscore the need for improved testing methods to ensure the safety of gluten-free products and protect consumers.
