Primary Outcome Measures:
  • Gut hormone secretion [ Time Frame: 300 min ]

Secondary Outcome Measures:
  • Insulin secretion [ Time Frame: 300 min ]

Enrollment: 12
Study Start Date: May 2011
Study Completion Date: September 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Oral amino acid mixture
Oral administration of amino acid mixture in healthy volunteers
Other: Oral amino acid mixture
Amino acid mixture 2,93 ml/kg
Other Name: Amino acid mixture
Experimental: Intravenous amino acid administration
Intravenous infusion of amino acid mixture in healthy volunteers
Other: Intravenous amino acid administration
Amino acid mixture 2,93 ml/kg
Other Name: Amino acid mixture

Detailed Description:
Amino acid mixture is given orally or intravenously to match total concentrations of amino acids in healthy subjects. Samples are taken regularly for 300 min after administrations. Plasma levels of the gut hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1)and determined and related to plasma levels of insulin and glucagon.
