I enjoy artificial sweeteners and haven't seen any benefit when I've cut them out. So I use them. I don't think an official stance against them is any better than an official stance for them, the research is sort of divided. Don't need it, so go with prudence and don't use it, just in case it's bad? Again, I enjoy the sweetness, and I don't consider enjoying food/taste a trivial benefit. Food is not just for nourishing our bodies, any more than speaking is merely for passing on data.
