Filter by:The study aims to determine in healthy subjects the bioavailability of protein and amino acids of pea protein isolate and casein isolate. For this purpose, the investigators will compare two methods: 1. the standard method consisting in measuring the ileal digestibility using ileal tubes, 2. an alternative method that has been proposed by an Food and Agriculture Organization (FAO) expert group: the dual isotope method.
Vascular function decreases following the intake of a mixed meal in some, but not all studies. Differences in the relative amounts of dietary fat, carbohydrates and protein present in the mixed-meal challenges may have contributed to these apparently inconsistent results. Well-designed trials - comparing under rigorously standardized conditions - on the effects of macronutrients on postprandial vascular function are missing. The primary objective of the current study is thus to evaluate in overweight and slightly obese men the effects of the three macronutrients (fat, carbohydrates, and protein) on postprandial vascular function, as assessed by brachial artery flow-mediated vasodilation (FMD). Secondary objectives are to examine postprandial effects on other markers reflecting vascular function, plasma markers for low-grade systemic inflammation and endothelial dysfunction, blood pressure, and serum lipid and plasma glucose metabolism.
This study investigates cold-induced brown fat activation assessed using PET/MR scans. Subjects will participate in an acute cooling intervention day and a thermoneutral intervention day with PET/MR scans on both days. A secondary purpose is to make a validation of an infrared thermography camera by comparison of skin temperatures and SUV of the supraclavicular brown adipose tissue.
This study investigates cold-induced brown fat activation in winter swimmers and not-winter swimmers by skin temperature measures assessed with infra red thermography imaging and skin temperatures. Winter swimmers and not-winter swimmers will participate in an acute cooling intervention and thermoneutral intervention for comparison of energy expenditure and skin temperatures at the supraclavicular area.
