Pre-meal whey protein improves glycemic control in type 2 diabetes.
Última actualización 1 de septiembre de 2026
Key finding
PPG iAUC was reduced by WP (−16%, P < .05).
This study investigated the effects of pre-meal whey protein on postprandial glycemia in adults with type 2 diabetes, finding significant reductions in glycemia and improvements in beta-cell function.

Plain-language summary
What this paper says
A plain-language read of the study’s main message and where it applies.
Study focus
This study investigated the effects of pre-meal whey protein on postprandial glycemia in adults with type 2 diabetes, finding significant reductions in glycemia and improvements in beta-cell function.
Clinical relevance
These findings suggest that incorporating whey protein into meals may be a beneficial strategy for managing blood sugar levels in individuals with type 2 diabetes. This could lead to improved dietary recommendations and better overall glycemic control, potentially reducing the risk of diabetes-related complications.
Keep in mind
The study's sample size and demographic diversity may limit generalizability. Short duration of the intervention may not reflect long-term effects. Potential confounding factors were not fully controlled.

Efectos Principales
Postprandial glycemia was reduced by 16% after whey protein (P < .05).
Beta-cell function improved by 40% after whey protein (P = .001).
Insulin clearance decreased by 22% after whey protein (P < .0001).
