Products containing high fructose corn syrup cannot be considered ‘natural’ and should not be labeled as such, the US Food and Drug Administration (FDA) has said.
…
Industry group Sugar Association, as well as consumer groups such as the Center for Science in the Public Interest categorically maintain that HFCS cannot be considered natural because its chemical bonds are broken and rearranged in the manufacturing process. The debate raged on for one simple reason: FDA does not define the term ‘natural’, and it has therefore been left open to different interpretations.

However, in response to an inquiry from FoodNavigator-USA.com, the regulatory agency examined the composition of HFCS, which it said is produced using synthetic fixing agents. “Consequently, we would object to the use of the term ‘natural’ on a product containing HFCS,” the agency’s Geraldine June said in an e-mail to FoodNavigator-USA.com. June is Supervisor of the Product Evaluation and Labeling team at FDA’s Office of Nutrition, Labeling and Dietary Supplements.
