This is the authors' abstract. We don't add key points for this paper.

, derived from α-lactalbumin, not only promoted GLP-1 secretion but also demonstrated significant DPP-IV inhibitory activity. These findings provide new insights into the functional potential of food-derived peptides, offering promising therapeutic avenues for regulating gastrointestinal hormones and improving metabolic health.
