NCT ID NCT07786675
First seen Aug 26, 2026 · Last updated Aug 27, 2026 · Updated 1 time
Summary
This randomized crossover trial tests whether nutritionally improved bread and bakery products—with less saturated fat and sugar and more fiber—can positively affect body composition and metabolic health in children aged 6 to 12 with overweight or obesity. Participants will consume these reformulated products for a period, then switch to conventional products, allowing each child to serve as their own control. The study measures changes in weight, body fat, lean mass, blood markers, and gut microbiota, along with how acceptable the products are to children.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Nutritionally improved bread and bakery products with reduced saturated fat and free sugars and increased fiber, compared to conventional products
- What this could lead to
- If effective, these reformulated products could offer a practical, everyday dietary strategy to help manage weight and metabolic health in children with overweight or obesity.
- What could go wrong
- This is a small crossover trial, and results may not generalize. The intervention is just one part of the diet, so its impact on body composition and metabolic markers may be modest or not clinically significant.
