If you train your palate to not need sweetners, you discover that many foods are in fact naturally sweet already. Even "bland" things like tomatoes or whole wheat bread, have a slight sweetness.
I now find that tea is undrinkable at fast food places. It is so sweet here in the south, that I call it hummingbird food!
I can't drink sodas straight anymore (if I'm given a free one with a sandwich.) I drink maybe half a can with the sandwich ... and then sip the rest for an hour, after lunch. Coffee, I now drink straight. Maybe add a little milk sometimes, that's it.
I can actually say that I don't like MegaCorp processed pastries like pop tarts any more. Way. Too.. Sweet...
