I realized that stuff was poison years ago, and stopped eating it years ago.
And sugar in my book includes corn syrup, cane juice, etc.
And I used to love that stuff.
My general rule is to be suspect of any substance that has to be cooked and/or undergo a lot of work to make it edible.
Because if it isn't theoretically edible "raw right off the tree or the hoof" it's probably not something we evolved to eat.
