Metabolic status is related to the effects of adding of sacha inchi (Plukenetia volubilis L.) oil on postprandial inflammation and lipid profile: Randomized, crossover clinical trial

Sacha inchi oil (SIO) is an attractive source of polyunsaturated acids oil. A randomized crossover clinical trial was done to evaluate SIO effects on postprandial lipids and inflammatory state caused by a high-fat intake. Twenty metabolically healthy (MH) and 22 metabolically unhealthy (MU) subjects consumed a high-fat breakfast alone or supplemented with SIO. The biomarkers were measured in serum upon fasting, and after 1 and 4 hrs after breakfast. Interleukin-6 (IL-6) expression was determined in mononuclear cells. In the MH group, SIO reversed the cholesterol increase [iAUC(HFM): 0.27 mmol/L/4 h (IQR: -0.07/0.81); iAUC(HFM+S): -0.18 mmol/L/4 h (IQR: -0.49/0.31) p = 0.037] and decreased interleukin-6 concentration. In MU group, SIO attenuated lipopolysaccharides increase and interleukin-6 expression [(FCHFM = -1.19 (IQR: -1.72/1.93) and FCHFM+S = -1.83 (IQR: -4,82/-0.01), p = 0.017]. The effects of a high-fat meal on postprandial lipids and inflammation could be modified by the addition of SIO, but the outcomes are depending on the metabolic individual status.
