肥胖会影响饮食质量与代谢物之间的关系,而非肥胖个体的相关性最明显. 肥胖改变了特定的代谢途径,突出了潜在的机制.
科学领域:
- 代谢学 代谢学 代谢学
- 营养科学 营养科学
- 肥胖问题研究研究
背景情况:
- 肥胖会显著改变新陈代谢,导致各种饮食与疾病的联系.
- 了解肥胖如何影响新陈代谢途径对于有针对性的干预至关重要.
- 与肥胖状况相关的代谢途径差异在很大程度上仍然不清楚.
研究的目的:
- 调查代谢物和饮食质量之间的横截面关联是否因肥胖状况而有所不同.
- 为了确定受身体质量指数 (BMI) 影响的特定代谢途径.
- 评估肥胖对饮食代谢物关系的影响.
主要方法:
- 在2832名参与者的7255个代谢物峰值上利用了非目标代谢量.
- 使用先验的饮食质量评分 (APDQS) 和按BMI进行分层分析.
- 应用线性回归和路径丰富分析以确定差异性关联和代谢活性.
主要成果:
- 代谢物与饮食质量的关联在没有超重或肥胖的参与者中最强.
- 180个代谢物峰值显示了与APDQS的关联,与BMI不同.
- 六个关键的代谢途径,包括胆酸和类固醇生物合成,表现出基于BMI的差异性活性.
结论:
- 饮食代谢物相关性在正常体重的个体中更容易被检测出来.
- 肥胖与不同的代谢途径有关,这表明代谢功能发生了改变.
- 这些发现表明,与肥胖相关的代谢干扰影响了饮食代谢物相互作用.
