Pulses: Optimizing Pulse Consumption for Cardiometabolic Health
University of Arizona
Summary
This randomized clinical trial aims to evaluate the effects of consuming two different doses of pulses (1.5 cups/week or 3 cups/week) in individuals with baseline intake below 1.5 cups/week, compared to a control group receiving standard nutrition education based on the United States Department of Agriculture's (USDA) My Plate guidelines. The main question the Pulses study aims to answer is: • What is the effect of increasing pulse consumption (in a dose-response manner) on specific cardiometabolic risk factors, including LDL-C, CRP, HBA1C, and blood pressure compared to standard nutrition education? For secondary outcomes, this study aims to answer the following: • Does increased pulse consumption improve the following: overall serum lipid profile (Total cholesterol (TC), HDL-C, Triglycerides (TG), diet quality (measured by the Healthy Eating Index), and participants self-reported satisfaction with life (SWLS) and Satisfaction with Food-related Life (SWFoL). All participants will attend biweekly classes and food demonstrations. The pulses groups will learn to prepare various pulse-based recipes, while the control group will receive guidance on preparing healthy meals following the USDA MyPlate recommendations.
Description
This is a randomized, parallel-arm study with 3 groups: 1) Control (Con). This group will receive educational materials and attend a series of 6 cooking classes focused on the USDA's MyPlate guidelines; 2) Pulses 1.5. This group receive nutrition education and attend a series of 6 cooking classes focused on both USDA's MyPlate guidelines, with a specific emphasis on how to incorporate more pulses into their diet. They will also receive 1.5 cup-equivalents of pulses per week for 6 weeks to take home with them to prepare and eat; 3) Pulses 3.0. This group will receive the same nutrition educati…
