It is challenging to scour all those labels. The easiest way to avoid it of course is to make from scratch.
But I can tell you that reduced fat triscuits are yummy and legal. Don't know about other crackers.
I couldn't believe how hard it was to find salad dressings without sugar. I now make my own or use Godess Dressing from Trader Joe's. I think TJ's has some other varieties too that are legal.
I don't like any of the legal cereals - Uncle Sam, fiber one, etc., so I have mostly given up cold cereal. It doesn't satisfy me that much anyway.
I stay away from any kind of bars. Too easy for me to overdo. I don't know of any legal ones, except maybe the Kraft SB Bars, but even those have things you probably don't want to eat, and also they are really good and if I buy a box, I'll eat the whole thing in a couple of days. If you have more self control than me, you may do better.
Hope this is some help!
