Oops, you're right I meant maltodextrin. But anyway, one sucralose (splenda) bad contains about 0.8 of malto which is about 3 calories. One this that doesn't contain any calories is saccharin, it once was though to cause cancer in rats, but the FDA has withdrawn it's warning. Not so good taste but still, if you drink 10 cups of tea a day, it may save you 30 cals a day that the splenda would give you.
