Role of Colonic Events on Metabolism and Appetite Control: A Synbiotic Approach

May 7, 2013 updated by: Elin Johansson, Lund University

Prebiotics and Probiotics as Means to Modulate Colonic Events, With Specific Focus on Metabolism and Satiety

The purpose of the study is to evaluate food factors related to colonically derived regulation of glucose metabolism (and related parameters) and satiety using a semi-acute meal study in healthy subjects as experimental model.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Differences in concentration of risk markers in blood, measured post-prandial after a breakfast meal.
Time Frame: Post-prandially after breakfast, 0-210 min
Variables (blood glucose, insulin, incretin, inflammatory markers, markers of colonic fermentation) are measured after two-weeks ingestion of test products. The experimental day is terminated after a lunch meal.
Post-prandially after breakfast, 0-210 min

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
voluntary energy intake
Time Frame: Post-prandially after breakfast, 0-210 min
Energy intake at lunch is measured after two-weeks ingestion of test products. The experimental day is terminated after the lunch meal.
Post-prandially after breakfast, 0-210 min
Subjective satiety
Time Frame: post-prandially after breakfast, 0-210 min
The subjective sensation of satiety, hunger and desire to eat is measured using a (VAS) questionnaire.
post-prandially after breakfast, 0-210 min
Differences in gut microbiota
Time Frame: Faecal samples are collected after 14 days intake of test- and reference product
The effect on gut microbiota of 14 days intake of test- and reference product are investigated in faecal samples.
Faecal samples are collected after 14 days intake of test- and reference product
