肠道微生物的食蛋白质发酵受蛋白质来源和供体性别的影响. 这些发现表明,特定于性别的饮食建议可能有助于预防与肠道屏障功能障碍相关的慢性疾病.
科学领域:
- 微生物学 微生物学
- 人体生理学 人体生理学
- 营养科学 营养科学
背景情况:
- 肠道屏障功能受损与全身炎症和慢性疾病有关.
- 肠道微生物群发酵未消化的蛋白质,产生可以损害肠道屏障功能的代谢物.
- 人们越来越认识到肠道微生物群组成的基于性别的差异.
研究的目的:
- 为了研究潜在的性别-饮食蛋白相互作用影响肠道屏障功能.
- 为了确定性别是否影响肠道微生物群在对饮食蛋白质的反应中修改屏障功能.
主要方法:
- 在体外发酵系统中用来自男性和女性的人类便样本进行注射.
- 补充各种非化蛋白质来源 (乳清,鱼,牛奶,大豆,蛋,豆,菌蛋白).
- 微生物种群的量化和代谢物度的分析.
主要成果:
- 增加的蛋白质可用性导致更高的蛋白质分解细菌和代谢物 (,p-cresol,英多尔,氨),因蛋白质类型而异.
- 男性的Clostridium IX集群和p-cresol增加,而女性的氨产量增加,无论蛋白质来源如何.
- 观察到显著的性别蛋白相互作用,影响细菌种群和代谢物概况.
结论:
- 肠道微生物群的蛋白质发酵受蛋白质来源和捐赠者的性别的影响.
- 研究结果表明,针对性别的饮食建议有潜力减轻慢性疾病的风险.
- 需要进一步的人体研究来证实这些体外观察结果及其临床影响.
