Study Details

The purpose of this study is to investigate the effects of replacing snacks higher in saturated fats and added sugars with pecans on blood sugar control, heart health and diet quality in individuals with prediabetes. Participants will be randomized into one of two groups. Group 1 will consume 1.5 oz of pecans per day in place of normally consumed snacks higher in saturated fat and added sugars for 16 weeks. Group 2 will be asked to continue consuming their current diet for 16 weeks. Measures will be taken to evaluate blood sugar, heart health and dietary intake at the beginning and 16 weeks later.
