First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study investigates whether eating a high protein diet for 10 days can improve the body's antioxidant capacity in healthy women aged 19–45. Participants follow both a high protein diet (about 30% of calories from protein) and a normal protein diet for 10 days each, with blood tests and body measurements taken after each period. The goal is to understand how short-term high protein intake affects oxidative stress and body composition, which could inform safer diet plans.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- high protein diet (30% of total energy from protein) for 10 days
- What this could lead to
- If successful, this study could clarify whether short-term high protein diets boost antioxidant defenses, informing safer dietary recommendations.
- What could go wrong
- This is a small, early-stage study in 20 healthy women, so results may not apply to other groups. The 10-day duration may be too short to see meaningful changes.
