A group of experts say sugar is a toxin and should be regulated just like alcohol or tobacco.

Robert Lustig, a pediatrician at the University of California, brands sugar a "toxin", deadly enough in high enough doses that it should be regulated just like alcohol in the latest issue of the journal, "Nature."

Lustig says sugar has a metabolic effect on the body that can lead to a host of chronic illnesses.

The experts believe sugar should be taxed, like tobacco, to motivate people to consume less.
