Summary

This study tests whether drinking whey protein before meals can help adults aged 75-90 with type 2 diabetes keep their blood sugar in a healthy range. Participants will take whey protein or a placebo before each meal for a week, and their blood sugar will be tracked continuously. The goal is to see if this simple dietary change can improve daily glucose control.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: whey protein
What this could lead to: If it works, this could point toward a simple dietary supplement to help older adults with type 2 diabetes manage their blood sugar levels better.
What could go wrong: This is a very small, early-stage trial with only 32 participants. The effect may be small or not apply to everyone. It is not a treatment for diabetes, just a potential aid.
