Abstract
A diet rich in plant foods and lower in ultra-processed foods is associated with reduced risk for chronic diseases. The purpose of this study was to determine whether an intervention promoting increased diversity of plant food varieties and including a grocery stipend was associated with reduced intake of ultra-processed foods and reduced risk for chronic disease. A dietary intervention trial was conducted with 19 college students who completed the 12-week study. Participants underwent a 4-week control period and an 8- week intervention period in which they watched weekly educational mod- ules on dietary diversity and received a weekly grocery stipend. Participants tracked the number of plant foods they consumed on a weekly basis and completed 24-hour recalls using ASA24. Anthropometric data (weight, waist and hip circumference, blood pressure, body composition) and labs (fasting glucose, lipid panel, C-reactive protein) were collected at baseline, and at the start and end of the intervention. There was a significant increase in average weekly number of types of plant foods consumed in the intervention compared to control (34.7 +10.8 vs. 23.1 + 12.1; p< 0.001). There was a significant reduction in average daily number of ultra-processed foods consumed in the intervention compared to the control (5.4 + 1.6 vs 6.5 + 2.0; p1⁄40.02). There were no statistically significant changes in the anthropometric or lab measures. A dietary intervention to increase the number of plant food varieties was associated with an increase in the types of plant foods consumed each week and a reduction in consumption of ultra-processed foods.
