Brief Summary:

Epidemiological data suggest, that not only sugar-based, but also artificially sweetened soft drinks may play a role in the development of diabetes.

Recent studies in animals and humans have shown, that artificial sweeteners (AS) influence metabolic responses after glucose ingestion, possibly alter the intestinal microbiome and even modulate incretin release.

Data on human subjects are sparse and controversial, especially in a long-term manner. We therefore conduct a cross-over study to assess metabolic response to sweetened vs. non-sweetened soft drinks, which are consumed over a period of 4 weeks.

Data on human subjects are sparse and controversial, especially in a long-term manner. We therefore conduct a cross-over study to assess metabolic response to sweetened vs. non-sweetened soft drinks, which are consumed over a period of 4 weeks. Metabolic assessment will be based on oral glucose tolerance tests.

Arm Intervention/treatment
Placebo Comparator: Non-sweetened soft drink
4-week-intervention with one liter of custom-made soft drink per day; soft drink does not contain glucose or any kind of sweet tasting substance
 Dietary Supplement: custom-made soft drink
Active Comparator: Sweetened soft drink
4-week-intervention with one liter of custom-made soft drink per day, soft drinks contains an amount of sweetener, which is isosweet compared to 100 g of sucrose in one liter of beverage
 Dietary Supplement: custom-made soft drink

Primary Outcome Measures :
  1. change in release of GIP [ Time Frame: 4 weeks (cross-over) ]
    change in fasting state and post-glucose release of GIP between the two interventions

  2. change in release of GLP-1 [ Time Frame: 4 weeks (cross-over) ]
    change in fasting state and post-glucose release of GLP-1 between the two interventions

  3. change in release of GLP-2 [ Time Frame: 4 weeks (cross-over) ]
    change in fasting state and post-glucose release of GLP-2 between the two interventions

  4. change in release of PYY [ Time Frame: 4 weeks (cross-over) ]
    change in fasting state and post-glucose release of PYY between the two interventions

  5. change in release of insulin [ Time Frame: 4 weeks (cross-over) ]
    change in fasting state and post-glucose release of insulin between the two interventions

  6. change in combined levels of glucose and insulin, expressed in calculated indices for insulin secretion [ Time Frame: 4 weeks (cross-over) ]
    change in fasting state and post-glucose insulin secretion between the two interventions

  7. change in combined levels of glucose and insulin, expressed in calculated indices for insulin sensitivity [ Time Frame: 4 weeks (cross-over) ]
    change in fasting state and post-glucose insulin sensitivity between the two interventions
