Introduction: Postprandial lipemia is a coronary risk factor and is affected by omega-3 fatty acids. There is evidence that omega-3 acids decrease plasma lipids. Plukenetia volubilis Linne (sacha inchi) is rich in omega-3. Objectives: To determine the effect of sacha inchi ingestion on postprandial triglycerides in young adults. Design: Quasi-experimental study. Setting: Faculty of Medicine, Universidad Nacional de Trujillo. Participants: Medical students. Interventions: To 12 randomly selected Universidad Nacional de Trujillo medical students we performed oral glucose tolerance test in two phases: in the first following the ingestion of 82 grams of olive oil and in the second adding 50 grams of sacha inchi. Main outcome measures: Plasma lipids reduction. Results: In the first phase we obtained an average of 99,67 mg/dL basal triglycerides that following the ingestion of the olive oil in...
