Effects of Diet Interventions on Monocytes in Metabolic Syndrome

Effects of Diet Interventions on Monocyte Phenotypes in Individuals With Metabolic Syndrome

Subjects with hypertriglyceridemia and metabolic syndrome are being recruited and receive diet interventions with either a high-saturated fat diet or a low-fat high protein diet for 4 days (days 1-4) and a breakfast on day 5. Blood samples are collected on day 1 and day 5 to examine lipid levels and circulating monocyte phenotypes.

Subjects with hypertriglyceridemia and metabolic syndrome are being recruited and receive diet interventions with either a high-saturated fat diet or a low-fat high protein diet for 4 days (days 1-4) and a breakfast on day 5. Blood samples are collected on day 1 at fasting state and on day 5 at fasting state and 4 and 6 hours after the breakfast to examine lipid levels and circulating monocyte phenotypes.
