Comparison of Dietary Fats on Vascular Parameters

Not Applicable

• Conditions: Healthy
• Interventions: Other: Coconut Oil; Other: Canola Oil; Other: Grapeseed Oil; Other: Chia Oil; Other: Butter

• Registration Number: NCT01876394
• Lead Sponsor: Unity Health Toronto

Brief Summary

The purpose of the study is to examine the effect of consuming 50g of fat from 5 different sources (coconut, canola, grapeseed, chia, and butter) on arterial stiffness, blood pressure and blood glucose levels. It is hypothesized that butter will have the most detrimental effect on acute vascular function. Canola, grapeseed and chia oil with their decreased content of SFA are hypothesized to impair vascular function to a lesser extent.

Primary Outcome Measures

Name	Time	Method
To compare 5 different dietary fat sources in a liquid meal on postprandial changes in augmentation index (AIx)	5 separate mornings, measurements taken at baseline and at 60, 120 and 180 minutes

Secondary Outcome Measures

Name	Time	Method
To investigate whether these dietary fat sources will result in blood pressure changes and a differential glycemic response	5 separate mornings, blood pressure measurements will be taken at baseline, 60, 120 and 180 minutes. Blood samples will be taken at baseline 15, 30, 45, 60, 90 and 120 minutes
