Environmental Factors and the Gut Microbiome - Endocannabinoid Axis (eMECA)
The Influence of Host Environmental Factors on the Gut Microbiome - Endocannabinoid Axis in Metabolic and Mental Health
研究概览
详细说明
The gut microbiome and the endocannabinoid system (ECS) could be interacting together and influence local enteric and peripheral metabolic functions and mental health.
The association of some host environmental factors (e.g. age, metabolic status, dietary habits) with gut microbiota composition and function has been investigated but, to our knowledge, little is known about their influence on the ECS.
There is also a need to better understand the influence of these factors and the interplay between the gut microbiota and the ECS and their relationship with intestinal, metabolic and mental health.
The investigators therefore propose to fill this knowledge-gap in the general population of adults with various body composition, dietary habits and daily physical activity levels.

主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Evaluation of the influence of dietary habits assessed via Food Frequency Questionnaire (FFQ) on the relationship between gut microbiota composition and circulating endocannabinoids
大体时间：September 2018
|
FFQ items will be used to identify dietary habits by unsupervised clustering to evaluate their association with gut microbiota composition obtained from ribosomal RNA sequencing and plasma endocannabinoid (e.g.
Arachidonoylethanolamide, 2 arachidonoyl glycerol and their derivatives) concentrations.
