- Lipid Tolerance Test [ Time Frame: After 3 consecutive days of controlled feeding. ]Participants will come in after a 12-hour fast for a lipid tolerance test. Specifically, participants will consume a treatment breakfast meal and blood samples will be collected 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 360, and 420 minutes following ingestion of the treatment meal.
- EndoPAT [ Time Frame: After 3 consecutive days of controlled feeding ]Endothelial function will be assessed by measuring endothelium-dependent flow mediated dilation of the peripheral bed (EndoPAT, Itamar Medical, Israel). Immediately after the test, a blood sample will be collected for measurement of serum triglycerides.
- Genetic testing [ Time Frame: After 3 consecutive days of controlled feeding ]Blood will be used to test for genetic traits that may influence nutrient metabolism and also traits reflecting the mechanisms that may be influenced by the intervention.
- Microarray and targeted gene expression testing [ Time Frame: After 3 consecutive days of controlled feeding ]Blood samples will be used to test how the intervention affects gene expression. Global gene expression will be performed for a complete survey of the RNA response to the intervention, and targeted gene expression will be performed to confirm the findings of the global gene expression analysis.
