What is the theological explanation of why sugar cane, beets, and corn are tainted with original sin and the other plants are not?

Many bottled fruit juices have their bulk made of juice from a cheaper fruit that doesn't match the label...but it's not sugar cane, beets, or corn. Does this make them ok?

To your question, I honestly don't think the WHO would base their definition of "free sugar" on anything with theological underpinnings outside the domain of sound science.
