The addition of sacha inchi oil decreases the postprandial granulocyte/lymphocyte ratio produced by a high-fat meal in healthy adults

The postprandial stage is related to an increase in biochemical and cellular inflammatory markers. The objective of this study was to evaluate the postprandial effects of the addition of Sacha inchi oil on the concentration and size of leukocytes, erythrocytes and platelets, and on inflammation markers, after the ingestion of a high-fat meal. A sample of 42 seemingly healthy male individuals consumed two high-fat breakfast meals, one with the addition of 15mL of oil rich in polyunsaturated fatty acids (omega 3 and 6 series), extracted from Sacha Inchi seeds. Fasting blood samples were taken at 4 hours postprandial to determine hematological variables (number and size of leukocytes and platelets and percentage distribution of leukocytes) and biochemical variables such as interleukin 6 (IL6) and high-sensitivity C-Reactive protein (hs-CRP). The concentration of CRP and leukocyte and platelet counts increased following ingestion of both types of breakfast. The addition of Sacha inchi oil increased the percentage of lymphocytes (p= 0.005) and decreased that of granulocytes (p= 0.012), reversing the increase in the granulocytes / lymphocytes ratio evidenced after fat intake. The percentage of intermediate-sized cells and postprandial concentrations of IL6 also decreased. In conclusion, the addition of 15.0 mL of Sacha inchi oil to a high-fat breakfast modulates the relationship between different leukocyte populations, which could mitigate postprandial inflammatory effects and cardiovascular risk.
