Question!
 

I guess we need to be able to make a distinction between calorie/fat/carb/sugar free and "good for you". That sort of stuff is processed within an inch of its life and probably bears no resemblance to organic food matter. No doubt they make it in test tubes in labratories. :) It is certainly not good for you--someone more knowledgeable than I could explain why not--but it probably won't hurt your diet. That said, I personally would much rather eat real food that tastes delicious with calories in it (an apple, say, or some dark chocolate) than food made out of plastic and corn syrup that tastes predominantly sweet and synthetic. For me, committing to a healthy lifestyle means training my tastebuds and cravings away from super-processed foods and towards real food with an actual nutritional content. But people feel differently about these things.

I think if you are asking if it is really good for you, I'd say probably not. There are a lot of things that we eat that I wouldn't consider "really good for you" but people still eat them.

I would much rather eat something natural than something artificially made to be 0 calories. If it helps you though then that is up to you on whether or not to eat it.

Ok thanks all for the help!

The advice so far sounds about right to me....
I think if we let ourselves learn to eat foods in their more natural, less processed, state, we will come to see how delicious they are. I still bake (often with my daughter--fun to do it together!): we use whole wheat flour, unsweetened applesauce, ff yogurt, grapeseed oil, etc. We still use some butter and oocasionally a bit of white sugar. All in all, we've reduced the fat/sugar content of our recipes and we still make delicious things--pumpkin muffins, chocolate cake, banana-nut loaf, oatmeal cookies, etc.
