Charles Sipos was quoted in "FTC Official: Research Needed to Study Consumer Understanding of ‘Natural,’" an article in Natural Products INSIDER, regarding the term "natural" in the labeling of human food.

“I think at this stage, that … isn’t really necessary or appropriate because the FDA has already acted," he said, referencing FDA’s 2015 Federal Register notice.

Finally, Sipos argued FTC’s nominal interest in the “natural" issue thus far reflects “the fact that even as to natural claims that have been challenged in an ongoing litigation, there’s just not much quality of proof there that consumers are being misled by these claims."
