I like Splenda:
Here's some stuff from the Splenda Website.
McNeil Nutritionals' SPLENDA® No Calorie Sweetener, the top-selling low/no-calorie sweetener in United States, is the only low-calorie sweetener that is made from sugar, tastes like sugar and can be used virtually anywhere sugar is used, including in cooking and baking. SPLENDA® No Calorie Sweetener is the result of years of research and testing of the sweetening ingredient sucralose, a substance that has been found to be safe for everyone, including those with diabetes. Unlike sugar, sucralose cannot be broken down and utilized for energy in the body. This means that sucralose provides a great sugar-like taste without any calories.
An Outstanding Safety Profile
Safety studies show that sucralose is a safe and essentially inert ingredient. Conclusions from the studies include the following:
No known side effects
Not toxic: No adverse effects seen in test animals, even in amounts equivalent in sweetness to 40+ pounds of sugar per day for life
No bioaccumulation
Not carcinogenic
Not genotoxic: Does not cause genetic mutations
No effects on fetal or neonatal development
Not neurotoxic: No evidence of effects on the central nervous system
Not cariogenic: Although sucralose is derived from sugar, it is not used by oral bacteria that cause tooth decay. The maltodextrin and dextrose that are added to the granular and packet forms of SPLENDA® No Calorie Sweetener have some cariogenic potential, but studies have shown that these SPLENDA® products may be preferable to sugar when comparing potential for causing dental caries
No effect on carbohydrate metabolism
No calories or carbohydrate: Sucralose is not hydrolyzed or otherwise broken down for energy
No effect on short- or long-term blood glucose control or on serum insulin levels*: Sucralose is suitable for people with diabetes and may be used as part of an overall healthy diet designed to meet their unique dietary needs
