On average, Splenda has 3 cals per gram (teaspoon). Splenda calls their product sucralose because that's the sweetener they use. BUT that's not the only thing in their product.

RAW sucralose is practically a 0 calorie sweetener. You'd have to go through an ass load of that stuff to get a couple of calories. But Splenda wants to market their product as being equal in sweetness with the same volume as sugar. Well, raw sucralose is a much lower volume. So they 'fluff' it up with malto. Hence where the cals come from.

Anywhoooo.... Any product that uses an artificial sweetner, just know what kind of sweetener they're using.

Things like aspartame, even though they're not the greatest for you, are ok in small doses. If it says sucralose, check to see if it says Splenda brand sucralose. If it does, it's practically the same as sugar in terms of cals.

Stevia, I'm still researching, but thus far seems to be the big 'natural' sweetener. As far as if it's better for you, I have no conclusions on that yet. But the reports so far are leaning toward the positive side.

One of the newest crazes, which I don't think TP has on their order form yet, is agave. I have yet to look very deeply into that one, though.

Overall, when ordering things with artificial sweeteners, just be mindful of A) what sweetener it is and B) how much they're using. It's best to minimize anything artificial. And since Stevia is more natural, that's obviously a better choice.
