splenda actually has 4 calories per packet, but because of FDA regulations they dont have to "technically" put that on their labels so you are consuming calories.
another interesting fact about splenda is its chlorinated sugar, so when your body takes the sucrose from the molecule to use it as energy when it gets into your system negative chlorine ions are left floating around in your body. and since their are no "long term" studies that have been conducted on users of splenda because it only been around for 10 years you dont really know if this could be detrimental
just thought youd like to know
