I found info on the Splenda website (

"Q: Can people with diabetes use SPLENDAŽ No Calorie Sweetener?
A: Yes. Numerous studies have shown that SPLENDAŽ Brand Sweetener, or sucralose, is suitable for people with diabetes. Sucralose is not recognized by the body as sugar or as a carbohydrate. It is not metabolized by the body and does not affect blood glucose levels. Sucralose has no effect on carbohydrate metabolism or insulin secretion. Foods and beverages sweetened with SPLENDAŽ Brand Sweetener can provide good-tasting, lower-calorie alternatives for people with diabetes who are interested in reducing their calorie or sugar intake. As always, people with diabetes should consult their doctors or diabetes healthcare professionals for advice on an individualized dietary plan. "
