Somersweet does contain some fructose, but that's not the main ingredient ( I don't have any with me right now to check what is). But my point is that both somersweet and Splenda are said NOT to cause any insulin release, which is the whole point of avoiding AS in the first place, so I wonder if anyone has any info or experience about this. I think it is interesting in light of the fact that the Hellers say that even tasting something that tastes like sugar can cause an insulin spike, even if it's not really sugar.... and the research would seem to contradict this...
