Similar research involving protein hydrolysate interventions in T2DM have yielded significant results, such as Wang et al. who fed walnut protein hydrolysate (3–10 kDa) at concentrations of 200, 500, and 800 mg/kg/d orally to T2DM mice (n = 10) and reported that after 4 weeks, the mice showed a 64.82% reduction in fasting glucose levels and a 23.71% increase in insulin secretion [30]. Here, INS is linked to type 2 diabetes mellitus.
