Groups/Cohorts Assigned Interventions
1
High omega-3
 Other: Omega-3 study meal
Participant will eat a study meal high in omega-3 fatty acids.
2
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.
