NUTRALYS? pea protein: characterization of in vitro gastric digestion and in vivo gastrointestinal peptide responses relevant to satiety

Abstract

Laboratory and intervention studies indicate that increasing dietary protein levels may aid weight control via several mechanisms, such as enhanced within-meal satiation and between-meal satiety, stimulation of post-meal energy expenditure and conservation of metabolically active lean body mass during reduced-calorie diets (2, 3). [...]post-ingestive physiological signals and effects on body weight vary among different types of dietary protein (4-7). (8) because its molecules aggregate to form a larger protein network within the acidic stomach milieu, in a process that delays nutrient entry to the small intestine, resulting in the small-intestinal absorption of casein's amino acids and their appearance in the circulation (5). [...]viscosity measurements were performed using a controlled stress rheometer (AR-2000; TA Instruments, New Castle, DE, USA) equipped with a stainless-steel vane geometry (stator inner radius 26.85 mm; rotor outer diameter 24.5 mm, height, 73 mm).
