Postprandial glucose‐lowering effect of premeal consumption of protein‐enriched, dietary fiber‐fortified bar in individuals with type 2 diabetes mellitus or normal glucose tolerance

Aims/Introduction Protein preload improves postprandial glycemia by stimulating secretion of insulin and incretin hormones. However, it requires a large dose of protein to produce a significant effect. The present study was carried out to investigate the postprandial glucose‐lowering effect of a premeal protein‐enriched, dietary fiber‐fortified bar (PFB), which contains moderate amounts of protein, in individuals with type 2 diabetes mellitus or normal glucose tolerance (NGT).
