Summary

This study looks at whether eating a daily serving of peanut butter at breakfast can improve blood sugar control, thinking skills, and heart health in middle-aged adults with prediabetes. Participants will either add peanut butter to their first meal or stick with their usual diet for 12 weeks. Researchers will measure changes in HbA1c, fasting glucose, and other markers of metabolic and cognitive health.
