Further study details as provided by Charles Couillard, Laval University:

Primary Outcome Measures:
  • Endothelial function measured by endopat system (the endothelium-mediated changes in vacular tone) [ Time Frame: at week 0 and week 4 ]

Secondary Outcome Measures:
  • Circulating level of plasma lipoproteins-lipids [ Time Frame: at week 0 and week 4 ]
  • Oxidative stress [ Time Frame: at week 0 and week 4 ]
  • Endothelial activation and inflammatory markers [ Time Frame: at week 0 and week 4 ]

Enrollment: 224
Study Start Date: March 2010
Study Completion Date: December 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)

Detailed Description:
The purpose is to assess whether the polyphenol/antioxidant content of different spices will affect endothelial function and other cardiovascular risk factors.
