There has been an increasing interest in nutraceuticals and functional foods in reducing appetite and to lose weight. We assessed the effect of oral pomegranate extract (PE) and PE juice (PJ) intake vs. placebo on satiety parameters in healthy volunteers. Twenty-eight subjects (mean age 34.5 ± 13.7 years, body mass index [BMI] 25.05 ± 3.91 kg/m2) were randomized to 3-week priming supplementation with PE (Pomanox®) or placebo. On week 3, satiety parameters were determined on 1 testing day after participants ingested a breakfast and a lunch meal with PJ juice, using 100-mm visual acuity scales (VAS) for hunger, desire to eat, fullness and satisfaction. Meal quality and palatability were also tested. The desire to eat was less at all time points in the PJ juice with PE priming group and participants were also less hungry (p = 0.044) than those who consumed placebo. There was an overall significant difference between the groups (p < 0.001). Participants in the PJ juice with PE priming group experienced significantly greater satisfaction (p = 0.036) and feeling of fullness (p = 0.02) than those in the placebo group. These findings suggest that consumption of PE could have the potential to modulate satiety indicators.
人们对营养保健品和功能性食品在降低食欲及减肥方面的兴趣与日俱增。我们评估了口服石榴提取物(PE)和石榴汁(PJ)与安慰剂相比,对健康志愿者饱腹感参数的影响。28名受试者(平均年龄34.5±13.7岁,体重指数[BMI]25.05±3.91kg/m²)被随机分为两组,一组接受为期3周的PE(Pomanox®)启动补充,另一组接受安慰剂。在第3周,在参与者摄入含有PJ汁的早餐和午餐后,于1个测试日使用100毫米视力表(VAS)测定饥饿、进食欲望、饱腹感和满意度等饱腹感参数。同时也测试了餐食质量和适口性。与服用安慰剂的参与者相比,PE启动组饮用PJ汁的参与者在所有时间点的进食欲望均较低,饥饿感也较弱(p = 0.044)。两组之间总体存在显著差异(p < 0.001)。与安慰剂组相比,PE启动组饮用PJ汁的参与者体验到显著更高的满意度(p = 0.036)和饱腹感(p = 0.02)。这些发现表明,食用PE可能有调节饱腹感指标的潜力。
