Intestinal fructose metabolism triggers a GLP-1-β-cell axis to prevent post-fructose hyperglycaemia
Naoya Murao, Yusuke Seino, Risa Morikawa…·Atsushi Suzuki
This study shows that intestinal fructose metabolism increases GLP-1 secretion, which enhances insulin release and prevents hyperglycaemia, with this effect being impaired in obese diabetic mice.
