Official title: Acute Effects of Legume-enriched Meals Compared to Western Diet Meals on Postprandial Metabolic Response in Women and Men at Increased Risk of Cardiovascular and Neurodegenerative Diseases

Status Recruiting

Clinical Trial Summary

The aim of the study is to investigate the postprandial effects of legume-enriched meals compared to Western Diet meals on postprandial metabolism. In this context, older adults with increased risk for cardiometabolic diseases consume 4 mixed meals with 36 g or 62 g of protein either designed according to the Planetary Health Diet with legumes as primary protein source or the Western Diet with animal foods as primary protein source, in a randomized order. In a postprandial observation period of 6 hours, parameters of lipid metabolism, glucose and insulin metabolism, amino acid profile, as well as markers of inflammation and vascular function are analysed. Furthermore, neuropsychological parameters and satiety-associated hormones are investigated.

Clinical Trial Description

In a randomized crossover design, 30 older men and women with increased risk for cardiometabolic diseases consume 4 mixed meals, which differ in dietary pattern, protein source and protein quantity. Two meals are designed according to the Planetary Health Diet with legumes as primary protein source whereas the other two meals are designed according to the Western Diet with animal food as primary protein source. Two meals are designed as high protein meals (62 g of protein) and two meals are designed as low protein meals (36 g of Protein). Therefore, participants consume 4 different test meals, a Low and a High Protein Western Diet Meal and a Low and a High Protein Planetary Health Diet Meal in a randomized order. During a postprandial observation 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) and vascular function (e.g., pulse wave velocity) are analysed. Furthermore, amino acid profile, neuropsychologic parameters (e.g., appetite) and satiety-associated hormones (e.g., Ghrelin) are investigated. Each intervention will be separated by a washout period of approximately 14 days. ;
