Summary

This study tested whether giving adults with type 2 diabetes and food insecurity a small weekly incentive ($10.50 per household member) to buy healthy foods could improve their blood sugar control. 597 participants were randomly assigned to receive either the food incentive plus a healthy food prescription pamphlet, or just the pamphlet alone. The main goal was to see if the incentive group had lower blood sugar levels (measured by hemoglobin A1C) after 12 months.

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 incentive ($10.50/week/household member for 12 months)
What this could lead to
If it works, this could show that helping people afford healthy food improves blood sugar control and reduces diabetes complications.
What could go wrong
This is a completed study, but the intervention is small ($10.50/week) and may not be enough to make a lasting difference. Results may not apply to everyone with diabetes.
