简要总结
The aim of this cross-over intervention study is to investigate the influence of the sweet-modulating substance hesperetin in combination with sucrose in comparison to an equally sweet-tasting sucrose-only solution on markers of energy metabolism.
详细描述
The study is designed as a randomised cross-over intervention study with two arms. The aim is to investigate the influence of a 10% sucrose solution, corresponding to the sugar content of a conventional soft drink, compared to an equally sweet-tasting 7% sucrose solution in combination with 50 mg/L of the polyphenol hesperetin, on time-dependent blood glucose fluctuations and ad libitum energy intake in metabolically healthy male volunteers.
To investigate the underlying mechanisms, the individual appetite score, metabolic and hormonal responses to the interventions and circulating extracellular vesicles and their miRNA composition will be measured. In addition, the participants' individual thresholds for sweet taste, preference and consumption for sweet-tasting foods such as sugar and sweeteners, and their body composition will be recorded as potential influencing factors.
