Effects of Replacing High Fat and Sugar Snacks with Pecans on Blood Sugar and Heart Health in Adults with Prediabetes

What this Trial Is About

Researchers are evaluating the impact of replacing snacks higher in saturated fats and added sugars with pecans on blood sugar control, heart health, and diet quality in adults with prediabetes. This 16-week randomized controlled trial compares two groups to understand how pecan snacking affects these health factors in individuals aged 25 to 65 years who have prediabetes and meet specific health criteria. Participants will be randomly assigned to one of two groups. One group will replace their usual snacks with 1.5 ounces of pecans daily, while the other group will continue their habitual diet. Both groups will be followed for 16 weeks, with the pecan group receiving pecans and the usual diet group receiving a grocery voucher of similar value. Testing will occur at the start and end of the study period to measure changes. Throughout the study, participants will undergo assessments including blood sugar tests such as HbA1c, heart health evaluations, and dietary intake reviews at baseline and after 16 weeks. Researchers will monitor various health markers such as glucose levels, cholesterol, blood pressure, insulin resistance, and diet quality. The study aims to gather detailed information on how pecan snacking influences these outcomes, with safety and adherence closely observed during the 16-week participation.
