The best way to determine what foods are safe to eat... is to put a small amount of that "food" next to an ant hill. If the ants won't eat it, then DON'T eat it yourself.

Try an experiment. Place a small bowl of margarine outdoors, or equal or Splenda or most prepared & packaged breakfast foods. No insect will touch it. They know what is good to eat and what has no nutrition.

I've tried that with breakfast cereals. It would shock you that foods being marketed as "healthy" are avoided by the insects. Sometimes they really go for foods you wouldn't expect. One surprise was Captain Crunch Peanut Butter cereal. Ants loved that. They won't touch regular Captain Crunch cereal though. They will eat granola cereals and muselix cereals, but they avoid the high fiber or high protein cereals. I've also tried various breads, breakfast bars, and other "foods". If ants won't eat it, neither will I.

Try it for yourself.
