文章伴侣: aronia helanocarpa是(poly)酚的丰富来源。先前的研究表明,这些浆果可能会在高风险人群中提供心血管健康益处。但是,很少有研究研究了健康受试者中每天消费饮食可实现数量的浆果的影响。OBJECTIVES: The aim of this study was to investigate the effects of aronia berries on vascular function and gut microbiota composition in a healthy population.
METHODS: A double-blind, placebo-controlled, parallel设计的研究是在66名健康分配的健康男性中进行的,以食用(多)苯酚富含苯酚的提取物(116 mg,75 g浆果),全水果粉(12 mg,10 g浆果)或安慰剂(Maltodextrin)12周。评估了流动介导的扩张(FMD),动脉僵硬,血压,心率和血清生物化学。通过LC-MS分析血浆(聚)苯酚代谢产物。 Gut microbiota composition was determined via 16S rRNA sequencing in stool samples.
RESULTS: Consumption of aronia whole fruit and extract powder for 12 wk led to a significant increase in FMD over control of 0.9% ± 0.4% (95% CI: 0.13%,1.72%)和1.2%±0.4%(95%CI:0.36%,1.97%)。在第1天消耗Aronia提取物后2小时还观察到FMD的急性改善(1.1%±0.3%,p = 0.003)和12周后12周(1.5%±0.4%,p = 0.0001)。循环血浆酚类代谢物在食用Aronia治疗后增加。尽管在肠道菌群多样性中没有发现任何变化,但是芳香菌提取物的消耗增加了anaerostipes的生长(+10.6%,p = 0.01),而果芳基果实的整体水果显示出菌孢菌的显着增加(+193%,p = 0.01)。 Correlation analysis identified significant associations between changes in FMD, aronia-derived phenolic metabolites, and specific gut microbial genera.
CONCLUSIONS: In healthy men, consumption of aronia berry (poly)phenols improved endothelial function and modulated gut microbiota composition, indicating that常规的阿罗尼亚消费有可能维持心血管HEA患有心血管疾病风险较低的个体的lth。该试验在ClinicalTrials.gov上注册为NCT03041961。
