- Primary Outcome Measures
Name Time Method Change from Baseline (0 hr) in untargeted PBMC gene expression profile at 4 hr Prior to the initial intervention at 0 hr and after intervention 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)
- Secondary Outcome Measures
Name Time Method Postprandial interleukin (IL)-6 after acute intervention Prior to the initial intervention at 0 min and after intervention at 120 and 240 min. The venous blood samples will be taken for serum interleukin IL-6 analysis. Serum IL-6 analysis will be conducted with routine hospital analysis at Labmedicine Skåne.
Postprandial gastrointestinal tolerance ratings after acute intervention Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min. Gastrointestinal tolerance will be assessed using standard subjective 100 mm VAS (visual analogue scale) at respective time frame throughout each visit. Gastrointestinal tolerance questionnaire includes following questions: Do you experience any abdominal pain?, Do you experience any rumbling noises in your stomach?, Do you experience any flatulence (generation of excessive gas)?, Do you experience any bloated (swollen) feeling in the abdomen?, Do you experience any acid reflux (heartburn)?, Do you experience nausea?, Do you experience an urge to vomit?
Postprandial high density lipoprotein (HDL)-cholesterol after acute intervention Prior to the initial intervention at 0 min and after intervention at 30, 60, 90, 120, 180 and 240 min. The venous blood samples will be taken for plasma HDL-cholesterol analysis. Plasma HDL-cholesterol analysis will be conducted with routine hospital analysis at Labmedicine Skåne.
Postprandial non-esterified fatty acids (NEFA) after acute intervention Prior to the initial intervention at 0 min and after intervention at 30, 60, 90, 120, 180 and 240 min. The venous blood samples will be taken for serum NEFA analysis. Serum NEFA analysis will be conducted with routine hospital analysis at Labmedicine Skåne.
Postprandial interleukin (IL)-10 after acute intervention Prior to the initial intervention at 0 min and after intervention at 120 and 240 min. The venous blood samples will be taken for serum interleukin IL-10 analysis. Serum IL-10 analysis will be conducted with routine hospital analysis at Labmedicine Skåne.
Postprandial appetite ratings after acute intervention Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min. 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?
Postprandial blood glucose after acute intervention Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min. The capillary blood samples will be taken for blood glucose analysis.
Postprandial insulin after acute intervention Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min. The venous blood samples will be taken for insulin analysis. Insulin analysis will be conducted with routine hospital analysis at Labmedicine Skåne.
Postprandial triacylglycerol after acute intervention Prior to the initial intervention at 0 min and after intervention at 30, 60, 90, 120, 180 and 240 min. The venous blood samples will be taken for plasma triacylglycerol analysis. Plasma triacylglycerol analysis will be conducted with routine hospital analysis at Labmedicine Skåne.
Postprandial total cholesterol after acute intervention Prior to the initial intervention at 0 min and after intervention at 30, 60, 90, 120, 180 and 240 min. The venous blood samples will be taken for plasma total cholesterol analysis. Plasma total cholesterol analysis will be conducted with routine hospital analysis at Labmedicine Skåne.
Postprandial lipid peroxidation (MDA equivalent) after acute intervention Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min. The venous blood samples will be taken for lipid peroxidation (MDA) assay.
Postprandial total antioxidant capacity after acute intervention Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min. The venous blood samples will be taken for total antioxidant capacity (FRAP) assay.
Postprandial low density lipoprotein (LDL)-cholesterol after acute intervention Prior to the initial intervention at 0 min and after intervention at 30, 60, 90, 120, 180 and 240 min.
