角豆添加到高脂餐对主观饱腹感、胃饥饿素和PYY调节的影响
本研究为急性随机对照交叉试验,纳入20名健康男性,比较含角豆水提物与对照的高脂餐后180分钟内食欲相关激素及主观饱腹感。结果显示角豆餐降低主观饥饿感和进食欲望,增加满足感,并影响PYY和胃饥饿素反应,提示角豆可能改善餐后食欲调节,但因果关系未确立。
要点
- 角豆水提物加入高脂餐可降低主观饥饿感(p=0.011)和进食欲望(p=0.029),增加满足感(p=0.047)
- 角豆餐与对照餐的PYY曲线下面积存在差异(p=0.040),胃饥饿素从基线至180分钟的变化幅度在两餐间有差异(p=0.005)
- 研究仅纳入健康男性且为急性设计,长期效果和其他人群适用性尚不明确
核心结论
- 将角豆水提物加入高脂餐可能对餐后食欲和饱腹感调节产生有利影响
- PYY和胃饥饿素反应的差异可能介导这些效应,但因果关系未被证实
研究设计与样本
- 急性随机对照交叉试验
- 20名健康男性参与
- 两餐能量相近,含角豆水提物或橙味对照饮料,餐后监测180分钟
主要发现
- 角豆餐较对照餐主观饥饿感更低(p=0.011),进食欲望更低(p=0.029),满足感更强(p=0.047)
- 两餐间PYY曲线下面积有差异(p=0.040)
- 对照餐后胃饥饿素在30分钟下降(p=0.012),180分钟显著上升(p<0.005)
- 胃饥饿素从基线到180分钟变化幅度在两餐间有差异(p=0.005)
关键数值与推荐
- 主观食欲通过视觉模拟量表评估
- 激素检测包括肽YY(PYY)和胃饥饿素
- 观察窗为餐后180分钟
临床怎么用
- 对于需控制餐后食欲的个体,可考虑在高脂餐中搭配角豆水提物
- 但需更多研究确认长期效果及对食物摄入量的影响
局限性
- 急性研究设计限制长期结论
- 仅纳入健康男性,通用性受限
- 未确立因果机制

ABSTRACT Background Dietary components that influence appetite-related hormones and subjective satiety may help regulate food intake. Aqueous carob (Ceratonia siliqua L.) preparations may have a role in postprandial appetite regulation. Aims To investigate the effects of an aqueous carob preparation incorporated into a high-fat meal on postprandial appetite-related hormones and subjective satiety. Materials and Methods An acute randomized controlled crossover trial was conducted in 20 healthy males. Participants consumed two meals of similar energy content on separate occasions: a control meal containing an orange-flavoured beverage and a test meal containing an aqueous carob preparation. Blood samples and subjective appetite ratings, assessed using visual analogue scales, were collected over a 180-minute postprandial period. Results Compared with the control meal, the carob meal resulted in lower subjective hunger (p = 0.011) and desire to eat (p = 0.029), and greater satisfaction (p = 0.047). Peptide YY (PYY) area under the curve (AUC) values differed between meals (p = 0.040). Following the control meal, ghrelin decreased at 30 min (p = 0.012), followed by a marked increase at 180 min (p < 0.005). The magnitude of the change in ghrelin from baseline to 180 min differed between meal conditions (p = 0.005). Discussion The findings suggest that an aqueous carob preparation may improve subjective appetite responses when consumed with a high-fat meal. Differences in PYY and ghrelin responses may contribute to these effects, although a causal relationship was not established. The acute study design and inclusion of only healthy males limit conclusions about long-term effects and applicability to other populations. Conclusion Incorporating an aqueous carob preparation into a high-fat meal may favourably influence postprandial appetite and satiety regulation. Further research is needed to determine whether these effects persist over time and translate into reduced food intake.
