研究概览
简要总结
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.

结局指标
主要结局
To compare 5 different dietary fat sources in a liquid meal on postprandial changes in augmentation index (AIx)
时间窗: 5 separate mornings, measurements taken at baseline and at 60, 120 and 180 minutes
次要结局
- 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)
