Una molecola presente nella birra rinforza la membrana formata dalle cellule della parete intestinale, e quindi la barriera contro tossine e batteri. Lo hanno scoperto ricercatori della Scuola universitaria professionale della Svizzera nordoccidentale.
Le cellule della parete intestinale sono collegate tra loro da proteine che formano delle barriere impermeabili. Queste possono essere però danneggiate da alcune malattie o dalle intolleranze alimentari.
Una molecola presente nel luppolo e quindi nella birra, in particolare quella scura, è in grado di rafforzare e riparare queste barriere. I ricercatori raccomandano comunque di non aumentare il consumo di birra per proteggere l'intestino.
