Can eating more fiber help control diabetes? new study tests a simple nutrition program
NCT ID NCT07271940
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether an 8-week nutrition education program focused on fiber-rich foods (like fruits, vegetables, and whole grains) is acceptable and helpful for people with diabetes, prediabetes, or obesity. Researchers will track participants' weight and dietary changes over about 5 months. The goal is to see if this simple, clinic-based program can improve health outcomes.
