Sugar-replacement Sweeteners, Taste Perception, and Blood Sugar Control (ADAYP)
Several sugar-replacement sweeteners are currently on the market, including saccharine (ex. Sweet'N Low), aspartame (ex. Equal), and sucralose (ex. Splenda). The purpose of this study is to examine wether non caloric sweeteners affects how well the body works to control blood sugar. The study includes detailed blood sugar testing after drinking liquids that may contain sucralose. The investigators hypothesize that drinking liquids with sucralose will effect the amounts of specific appetite-affecting substances naturally produced by the body.

- The effect of sucralose on Glucagon Like Peptide -1 (GLP-1) release [ Time Frame: Baseline ] [ Designated as safety issue: No ]we will measure plasma GLP-1, glucose, C-peptide and insulin concentrations during a 5-hour modified Oral Glucose Tolerance Test (mOGTT) administered 10 minutes after subjects consume sucralose in water or an equal volume of water without sucralose (control condition).
- sucralose taste detection and GLP-1 (glucagon-like peptide - 1) levels [ Time Frame: baseline ] [ Designated as safety issue: No ]A measure of subject's ability to taste sucralose will be correlated with the hormonal response of GLP-1 during a 5-hour modified oral glucose tolerance test.
