A proposal to put artificial sweeteners in chocolate milk has generated controversy.

The U.S. Food and Drug Administration reports that it has received more than 30,000 comments on the issue to date. Read a statement from the FDA here.

“Based on these comments, we’re seeing a fair amount of confusion about what the labeling change would actually mean,” says Mary Poos, deputy director of FDA’s Office of Nutrition, Labeling and Dietary Supplements.

Much of confusion has to do with labeling and whether non-nutritive or artificial sweeteners would be included on the label.

“People commenting in response to the Federal Register notice appear to be under the impression that the non-nutritive sweeteners will not be listed anywhere on the product—which is not the case. They would still be named in the ingredients list on the package,” the FDA says.

The comment period remains open until May 21.

Read “Bad publicity for the dairy industry,” published by Dairy Herd Management in late February, which pointed out that non-nutritive or artificial sweeteners would be included on the label.
