Ah! Now I understand what you were asking! Sorry I didn't catch on right away.

Those items aren't in the database. You'll have to add it as a Custom Food.

For Splenda Granular:
Serving Size...............Calories......Carbohydrates

1 tsp. ............................2.................0.5g
1 cup ...........................96...............24g

For Splenda Packets:
Serving Size.......................Sweet as.........Calories.......Carbs

1 gram or 3/8 tsp. (1 pkt)....2 tsp. sugar..........4.............0.9g
2 grams or ½ tsp. (2 pkts)...4 tsp. sugar..........8............ 1.8g

I would count aspartame and any other dry sweetener the same, unless the package label stated otherwise. The carbs and calories come from the fillers that are necessary when these super-sweet sweeteners are made into a dry form for packaging.

For Liquid sweeteners (Sweetzfree, DaVinci's, Torani's, Stevia, etc.), I just count 0g.

Does that help?
