Objectives of the study
The purpose of this study was to compare the satiating capability of NUTRALYS® pea protein with a commonly used whey protein and establish if it can affect subjective ratings of appetite and some hormones secretion, and therefore if it could be suitable for promoting satiety as a good alternative to whey proteins when added to dietary products.
In this study, two concentrations of NUTRALYS® pea protein (30g and 15g) were tested for their satiating effect when incorporated in a preload vegetable soup, and compared to a control soup with no added protein (negative control) and a soup with 30g whey protein (positive control). NUTRALYS® seems to be a good candidate, as it induces, similarly to the whey proteins, a lower caloric intake than the control at both dosages and with no significant differences between the three products. Moreover, the NUTRALYS® soups were rated as modulating in some way the feeling of fullness, and induced modulation of gut hormones production. Taken together, these results demonstrated that the 30g NUTRALYS® soup led to increased perceived levels of satiety.
NUTRALYS® pea protein appears to be a high quality alternative candidate to animal protein, with similar bioavailability of amino acids and digestibility and a sustainable way of production (Yang et al., 2012).
Moreover, as an intermediate-fast protein, it can offer a better post-prandial utilisation and a better efficacy by inducing a better daily nitrogen balance.
