The gut is not just digestive and new evidence shows it actively controls brain function

This comprehensive review synthesizes a decade of human and animal research to explain how the gut and brain communicate through hormonal, neural, immune, and microbial pathways. It highlights how disruptions in these pathways contribute to gastrointestinal, metabolic, and neurological disorders, and how modern therapies are beginning to exploit gut–brain signaling for clinical benefit.

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.
