Free grocery vouchers could lower diabetes risk
NCT ID NCT05776420
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving a healthy food voucher to people with type 2 diabetes or prediabetes who have low income can improve their blood sugar control. About 390 participants will be randomly assigned to receive the voucher or not. The main goal is to see if hemoglobin A1c levels drop over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- healthy food voucher
- What this could lead to
- If it works, this could show that providing vouchers for healthy food helps control blood sugar in people with diabetes or prediabetes who struggle with food costs.
- What could go wrong
- This is a behavioral intervention, not a drug, so results may vary widely. The trial is still recruiting, and success depends on participants actually using the voucher for healthy choices.
