It is a real challenge to eat and avoid the corn syrup as it is in 3/4 of the spagetti sauces, bread (it makes it brown better), prepared frozen foods(it helps prevent freezer burn), wheat thins, most icecreams, yogerts, condiments(it makes the viscosity better so it is easyer to dispence), ...... and on and on...
if I go to someone's house who does not think about food haveing it in it I end up eating something simple as a majority of things have it.
Not trying to discourage you just letting you know my experience in finding foods without it.
if you decide to try to cut it out let me know and I can give you names of brands of prepared diet staples that are ok, as well as ideas of things to eat instead of somethings that just don't come without cornsyrup.
