In a crossover design, 30 older men and women with increased risk of cardiometabolic diseases consume 4 mixed meals, enriched with either 25 or 50 g canola or coconut oil. During a postprandial period of 6 hours, parameters of lipid metabolism (e.g., plasma triglycerides), glucose metabolism (e.g., plasma glucose, serum insulin), as well as markers of inflammation (e.g., IL-6), vascular system (e.g., pulse wave velocity) and antioxidant system (e.g., trolox equivalent antioxidative capacity) are analyzed. Furthermore, amino acid profile (e.g., L-arginine), fatty acid profile, neuropsychologic parameters (e.g., appetite) and satiety-associated hormones (e.g., PYY) are assessed. Each intervention arm will be separated by a washout period of 14 days.
The aim of this study is to investigate the postprandial effects of fat content and fatty acid composition of mixed meals on parameters associated with cardiometabolic diseases. Therefore, older subjects with increased risk of cardiometabolic diseases consume 4 mixed meals with 25 or 50 g of either canola or coconut oil. In a postprandial period of 6 hours, outcomes associated with cardiometabolic risk (e.g., triglycerides) are analyzed.
