Can a skin scan tell if your toddler eats enough veggies?
NCT ID NCT05855824
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test whether a simple skin scan can accurately measure how many fruits and vegetables toddlers eat. Researchers will give 150 healthy 2-year-olds either applesauce or a fruit-vegetable puree for 4 weeks, then compare skin carotenoid levels with blood tests and food diaries. The goal is to validate a non-invasive tool for better childhood nutrition research.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fruit-vegetable puree blend (carrot, banana, mango, sweet potato) and applesauce pouch
- What this could lead to
- If successful, this could give researchers a quick, non-invasive way to measure toddlers' fruit and vegetable intake, helping improve nutrition studies.
- What could go wrong
- This is an early validation study with no direct health outcome. The skin measurement may not match blood levels closely enough to be useful in practice.
