Impact of Pulse-enriched Foods on Cognitive Function and Cardiometabolic Health in Obese Adults — PULSA-2011  

Obesity Clinical Trial

Official title: Impact of Pulse-enriched Foods on Cognitive Function and Cardiometabolic Health in Obese Adults

Status Completed

Clinical Trial Summary

The Canadian population, as is the case in most developed countries, is ageing and becoming increasingly overweight and/or obese. Both ageing and obesity are associated with reduced cognitive performance which can impact adversely on the ability to undertake daily activities and increases the risk of loss of independent living and reduced quality of life. The investigators predict that consumption of ½ cup of pulses per day for 12 weeks will improve cognitive function in older overweight/obese adults and thus decrease the rate of cognitive decline that occurs in this at-risk population.

Clinical Trial Description

This is a multi-site, randomized, controlled, parallel, dietary intervention food study designed to examine the impact of pulse-enriched foods on cognitive function and cardiometabolic health in obese adults. Recruitment will consist of approximately 160 participants (n= 80 participants per site) at 2 sites located in Winnipeg and South Australia.

Participants will be randomly allocated to one of 2 groups; a pulse group or a control group. The pulse group will consume pulse-enriched foods designed to deliver ½ cup of pulses per day for 12 weeks. The control group will consume comparator foods for 12 weeks. The pulse and comparator food items will be provided to participants and they will be asked to incorporate these into their usual diet. Participants will be requested not to change their diet or physical activity habits during the study period, other than as required to comply with the study requirements. Five-day weighed food records will be completed during the week prior to baseline and during the final week of the study to monitor dietary intake, in particular intake of pulses. This will determine whether participants are incorporating the study foods as required, and will be used to evaluate associated changes in dietary intake and body weight, if they occur. ;
