Pulses: Optimizing Pulse Consumption for Cardiometabolic Health

What this Trial Is About

Researchers are evaluating how increasing pulse consumption affects cardiometabolic risk factors in adults who currently eat less than 1.5 cups of pulses per week. This study compares two different pulse intake levels—1.5 cups and 3 cups per week—against standard nutrition education based on the USDA's MyPlate guidelines. The primary focus is on changes in LDL cholesterol, C-reactive protein, HbA1c, and blood pressure, with additional interest in lipid profiles, diet quality, and life satisfaction measures. Participants are randomly assigned to one of three groups: a control group receiving general healthy eating education, a group receiving 1.5 cup-equivalents of pulses weekly along with targeted nutrition education, and a group receiving 3 cup-equivalents of pulses weekly with similar education. All groups attend biweekly cooking classes and food demonstrations over 12 to 14 weeks. Pulse doses are tailored to individual calorie needs and provided for participants to prepare and consume at home. Participants in pulse groups also complete weekly consumption logs. Throughout the study, participants undergo baseline and week-12 visits involving fasting blood draws to measure cardiometabolic biomarkers, blood pressure assessments under standardized conditions, and completion of questionnaires on diet and life satisfaction. Dietary intake is assessed using detailed 3-day food records at both timepoints. Physical activity is also monitored. Researchers track adverse events and medication changes. The study duration accommodates scheduling challenges by allowing intervention periods from 12 to 14 weeks.
