Postprandial Effects of Mixed Herbs and Spices on Pathways Associated With Glucose Homeostasis and Inflammation on PBMCs of Healthy Subjects

Postprandial Effects of Mixed Herbs and Spices on Pathways Associated With Glucose Homeostasis and Inflammation on PBMCs of Healthy Subjects - Molecular Insights Through Integration of Transcriptomics of Peripheral Blood Mononuclear Cells (PBMC) and Circulating miRNA

This study aims to investigate the effect of mixed of herbs and spices on gene expression of pathways associated with glucose homeostasis, oxidative stress, inflammation and its interrelation with circulating miRNA, in the postprandial phase in healthy human subjects.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from Baseline (0 hr) in untargeted PBMC gene expression profile at 4 hr	The venous blood samples will be taken for isolation of peripheral blood mononuclear cells. Extracted total RNA will then be used for running RNA-microarray (Illumina, San Diego, CA, USA)	Prior to the initial intervention at 0 hr and after intervention at 4 hr

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Postprandial appetite ratings after acute intervention	Appetite will be assessed using standard subjective 100 mm VAS (visual analogue scale) at respective time frame throughout each visit. Appetite questionnaire includes following questions: How hungry do you feel?, How strong is your desire to eat?, How satiated (i.e. pleasantly satisfied) are you?, How full do you feel?, How much food do you think you can (or would want to) eat?, How thirsty are you?
