Summary
This study evaluates a program called Vegetables for All in Uganda, which sets up special market zones and runs media campaigns to make fresh vegetables more available and appealing. Researchers will track whether women and children ages 3-9 eat more vegetables as a result. About 4,600 people are taking part in surveys and interviews to measure the program's impact.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- Food system and demand generation (behavioral intervention)
- What this could lead to
- If successful, this program could show how to increase vegetable intake in low-income urban areas, potentially improving nutrition and health.
- What could go wrong
- This is an observational evaluation, not a controlled trial, so results may not prove cause and effect. The program's success depends on many local factors.
