Primary Outcome Measures:
  • To measure flow-mediated dilation before and after eating the two study meals. [ Time Frame: Study visit 1 and 2 ]

Secondary Outcome Measures:
  • To compare the effect of different dietary fats on endothelial function. [ Time Frame: Study visit 1 and 2 ]

Estimated Enrollment: 50
Study Start Date: January 2008
Estimated Study Completion Date: January 2010
Estimated Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
High omega-3
Other: Omega-3 study meal
Participant will eat a study meal high in omega-3 fatty acids.
High saturated fat
Other: Saturated fat study meal
Participant will eat a study meal high in saturated fat.

Detailed Description:
This study requires two visits. Once determined eligible by the study criteria, during the first visit the participant will be randomly placed to receive one of two high-fat meals. The participant will receive the other study meal during the second visit. At each visit, brachial artery ultrasounds will be performed before and 3 hours after the meal is eaten. The sample size is 50 subjects. This study will be conducted at the Clinical Research Center at Tufts Medical Center.
