Sugar is only 16 calories a teaspoon (about what a cup of coffee needs), so there is really no reason to use the artifical stuff.
And for the folks who do so “to avoid sugar” the challoh and danish you eat (unless its whole wheat) mostly turns to sugar anyways, so the teaspoon of the real stuff is the least of their concern.
If anything, the packets of the artifical stuff give a measured serving size (as opposed to just spooning in the real thing) so perhaps that’s a benefit worth considering.
But how can something manufactured me better than the real thing?
I once heard that the “sweetner” in a packet of Splenda is really only a few granules, and the rest of the packet is just a carring agent. Can something that potent be healthful? Hmm…
