Effect of two bakery products on short-term food intake and gut-hormones in young adults: a pilot study

Int J Food Sci Nutr. 2015 Aug;67(5):562-70. doi: 10.1080/09637486.2016.1180348.

Abstract

The aim of this study is to compare the effect of conventional bread and a whole grain bread on appetite and energy intake, satiety and satiety gut-hormones. A randomized controlled crossover pilot study was carried out in 11 university students (age: 18.7 ± 0.9 years; body mass index: 22.7 ± 2.7 kg/m(2)). Participants consumed two different mid-morning cereal-based snacks, including a conventional or whole grain bread. Two testing days were completed, including satiety questionnaires, blood sampling and consumption of standardized breakfast, mid-morning test-snacks and ad libitum lunch. Several gut-hormones were analysed and satiation was assessed using Visual Analogue Scale scores. The consumption of whole grain bread increased satiety perception, decreased the remained energy intake during the testing day, and decreased the postprandial response of peptide YY, compared with conventional bread (p < 0.005). These data suggest that the consumption of whole grain bread might be a useful strategy to improve satiety.

Keywords: Dietary fibre; energy intake; ghrelin; peptide YY; satiety; whole grain.
