Summary

We investigate the impact of taste receptors (sweet, bitter and umami) on human metabolism. There ist growing evidence, that components of the taste signalling system, including the taste receptor proteins , have important functions in the regulation of metabolic parameters in non-gustatory tissues.

Conditions

  • Disorder of Glucose Regulation

Interventions

DIETARY_SUPPLEMENT

sweet block

oral application of the above mentioned substances in 300 ml tap water in 5 min. , collection of blood at 0,15,30, 60 ,120,180 minutes for measurement of incretins GIP(gastrointestinal polypeptide) and GLP-1 (glucagon like peptide 1), Protein hormones PYY(Peptide YY),CCK (cholecystokinin), Leptin and Insulin

DIETARY_SUPPLEMENT

bitter block

oral application of the above mentioned substances in 300 ml tap water, collection of blood samples at -15,0,15,30,60,120,180 min for Insulin, GIP,GLP-1, PYY and glucose

DIETARY_SUPPLEMENT

umami-block

oral application of umami substances as glutamate with and without IMP, collection of blood samples as above

OTHER

gastroscopy

gastroscopy with and without oral application of saccharin, tissue samples from th upper duodenum by endoscopy for the detection of taste receptor cells in the upper bowel
