The Food and Drug Administration is failing to protect children from the disturbing behavioral problems caused by artificial food dyes, even though evidence of those problems has continued to mount since 2011, when an FDA advisory panel last considered the issue. That’s the finding of a new report, released today by the nonprofit Center for Science in the Public Interest, that takes a withering look at the agency’s inaction on dyes in the face of what CSPI says is a growing consensus among researchers and healthcare providers who treat behavioral problems that avoiding food dyes benefits some children.
