However, the FDA said it defines sugar as a solid, dried and crystallized food -- not a syrup.

Separately, the Corn Refiners Association has also been running a marketing campaign to explain that its syrup is actually a form of sugar and has the same nutritional value as the familiar white, granular table sugar that consumers are familiar with. That, in turn, prompted a lawsuit from the Sugar Association last year claiming that the campaign is misleading.

Dan Callister, a lawyer for the Sugar Association, said the FDA's decision confirms his group's position that sugar and HFCS are two distinct products.

"What's going on here is basically a con game to suggest otherwise," Callister said. "What do con men do? They normally try to change their name. The FDA has thankfully stopped that."

The Corn Refiners Association issued a statement noting that the FDA denied its petition on "narrow, technical" grounds.

The group said it stood by its claim that "the vast majority of American consumers are confused about HFCS." Despite the name, the Corn Refiners Association says the most common forms of it are about half fructose and half glucose.

The American Medical Association has said it wants more research on HFCS but says there is not enough evidence to restrict its use for now. The Center for Science in the Public Interest has said there was no evidence that the sweetener is any worse for the body than sugar — and that Americans consume too much of both of them.
