Glucagon-like peptide-1 secretagogue, glucagon-like peptide-1 secretagogue food or drink, inhibitor of postprandial rise in blood glucose, and inhibitory food or drink of postprandial rise in blood glucose

Abstract

The invention relates to a GLP-1 secretagogue and an inhibitor of postprandial rise in blood glucose, containing κ-casein as an active ingredient, and a food or drink for promoting GLP-1 secretion and an inhibitory food or drink of postprandial rise in blood glucose, containing a milk-derived casein protein wherein κ-casein accounts for 60% by mass or more of the milk-derived casein.

1 . A glucagon-like peptide-1 secretagogue, comprising κ-casein as an active ingredient. 
   
   
       2 . A glucagon-like peptide-1 secretagogue food or drink, comprising a milk-derived casein protein, wherein κ-casein accounts for 60% by mass or more of the milk-derived casein protein. 
   
   
       3 . The glucagon-like peptide-1 secretagogue food or drink according to  claim 2 , further comprising a carbohydrate. 
   
   
       4 . An inhibitor of postprandial rise in blood glucose, comprising κ-casein as an active ingredient. 
   
   
       5 . An inhibitory food or drink of postprandial rise in blood glucose, comprising a milk-derived casein protein, wherein κ-casein accounts for 60% by mass or more of the milk-derived casein protein. 
   
   
       6 . The inhibitory food or drink of postprandial rise in blood glucose according to  claim 5 , further comprising a carbohydrate.
