Orange juice may boost insulin sensitivity in overweight women
NCT ID NCT01201603
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether drinking orange juice every day can help overweight women become more sensitive to insulin, a hormone that controls blood sugar. Thirty-six women will drink either orange juice or a sugary orange drink for three months. Researchers will measure insulin sensitivity, blood fats, and gene activity in fat tissue to see if the antioxidants in orange juice make a difference.
