Brief summary
The aim of this study is to investigate the potential effect of a marine protein hydrolysate (MPH) supplement before a meal on postprandial glucose tolerance in healthy subjects, to achieve more knowledge on this presumed beneficial, blood glucose lowering effect
Detailed description
To further investigate the effects of MPH in a single dose of 20 mg/kg of body weight on postprandial blood glucose, insulin and GLP-1 (as markers of glucose metabolism) in healthy, active middle-aged to elderly subjects - age 40-65 years.
Interventions
Marine (Cod) protein hydrolysate
Maltodextrin/Casein

Study design
Intervention model description
A double-blind crossover trial, including two different study days, with 4-7 days wash-out (WO) period in between. The intervention implemented 20 mg of MPH per kg body weight (test material) or control (casein).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Glucose | First sample fasting baseline, thereafter repeated samples every 20 minutes (i.e.20, 40, 60, 80, 100,120,140 minutes after baseline), last at 200 minutes after baseline. | Postprandial glucose (mmol/L) change on each day of intervention |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Insulin | First sample fasting baseline, thereafter repeated samples every 20 minutes (i.e.20, 40, 60, 80, 100,120,140 minutes after baseline), last at 200 minutes after baseline | Postprandial Insulin (mIE/L) - change on each day of intervention |
| Hormon 1 | First sample fasting baseline, thereafter repeated samples (i.e.20, 40, 60, 100 minutes after baseline), last at 200 minutes after baseline | Glucagon like peptide 1 (GLP-1) pmol/l change on each day of intervention |
| Visual analogue scale (VAS) | First (baseline) symptomscore (as described above) measured fasting , thereafter repeated symptom score i.e. at 20, 40 minutes after baseline, last symptom score measure at 200 minutes after baseline | Assessed by questionnaire VAS, scale from 0-10, where 0 is minimum score and 10 is the maximum score, reported e.g. as a total score of 7. The higher the reported value is the worse outcome. |
| KANE, symptom score | First (baseline) symptom score (as described above) measured fasting and the next measure at 200 minutes after baseline | Assessed by questionaire KANE (family name) , scale from 0-10, where 0 is minimum score and 10 is the maximum score, reported e.g. as a total score of 7. The higher the reported value is the worse outcome. |
