Few well‐controlled clinical studies have evaluated the health benefits and potential uses for pulses as a nutraceutical. Some evidence in animal models suggests that pulse consumption elicits a change in body composition. The purpose of this study was to evaluate the efficacy of pulse and pulse fractions to elicit a change in body fat in humans while keeping body weight constant. Hypercholesterolemic volunteers (N=17) were enrolled to participate in a triple crossover study. Subjects were randomized to receive 50 g/d white wheat flour (WWF), 11 g/d pea hull flour (PHF) or 50 g/d whole pea flour (WPF) for three 28‐day phases, separated by 28‐day washout periods. During the study periods, participants consumed a fixed diet under partial supervision, individually tailored to their caloric requirement. Dual X‐ray absorptiometry was used to determine end‐point and percent changes in lean (LBM) and fat (FBM) tissue between day 1 and 29 of each treatment phase. Neither whole nor fractionated pea flours elicit any change in body composition compared to control (LBM: WWF 48.18 ± 1.73 kg, PHF 49.70 ± 1.73 kg, WPF 49.79 ± 1.73 kg; FBM: WWF 33.64 ± 1.68 kg, PHF 33.91 ± 1.67 kg, WPF 33.28 ± 1.67 kg) (p>0.05). The present study suggests that previously reported effects of pulses on body composition are unlikely due to a direct phytochemical effect on cellular metabolism, rather due to reduced caloric intake.
