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.
