Saturated fatty acids of different chain lengths are metabolised differently, however, their effects on blood lipids are not clearly understood. This study aimed to investigate the impact of medium (MC-SFA) and long (LC-SFA) chain saturated fatty acids on postprandial lipaemia. After an overnight fast, healthy volunteers consumed biscuits containing 40 g of either butter (BB), coconut oil (CB) or lard (LB) in a randomised cross-over study with a minimum 7-day washout period between treatments. Blood samples were collected at baseline, 2, 3, 4 and 6 h postprandially and assessed for total cholesterol (TC) high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG). Sixteen participants (male/female, 8/8; BMI, 23.7 ± 2.8; age, 26.2 ± 8.4) completed the study. Postprandial TG response determined by area under the curve (AUC) following CB was 59.8% lower than after BB (p < 0.01) and 58.8% lower than LB (p < 0.01). The net AUC for LDL-C was significantly higher after CB compared to the BB consumption, despite no differences in net AUC for TC and HDL-C. Consumption of MC-SFA resulted in lower postprandial TG concentrations compared to LC-SFA suggesting that food source rather than saturated fat content determines their lipemic responses.
