Personally, I don't like any artificial sweeteners. Every one I've tried has a funny taste, and I just don't trust them. They also break 2 of the rules that I try to eat/cook by (from Food Rules by Michael Pollan)
1. Eat food. Though in our current state of confusion, this is much easier said than done. So try this: Don't eat anything your great-great-grandmother wouldn't recognize as food.
3. Especially avoid food products containing ingredients that are a) unfamiliar, b) unpronounceable c) more than five in number
I'm fairly certain my great great grandmother would not recognize splenda, aspertame etc. as food - and, once you look at the actual chemical in them instead of the brand name, good luck pronouncing it.
I'll stick with my sugar, thankyouverymuch
