FDA panel votes to study food dyes, hyperactivity

March 31, 2011 By MARY CLARE JALONICK , Associated Press

(AP) -- A Food and Drug Administration advisory panel recommended Thursday that the agency further study the link between food coloring and childhood hyperactivity but said products that contain the dyes do not need package warnings.

The committee, made up of doctors, scientists and consumer representatives, narrowly voted 8-6 that food packages don't need warnings flagging food colorings that could affect attention deficit disorder in children. Packages now must list the food colorings, but there is no warning about a possible link to .

The panel agreed with the FDA and affirmed that there is not enough evidence to show that certain food dyes cause hyperactivity in the general population of children. They also agreed that diets eliminating food dyes appear to work for some children with behavior problems.

The advisory committee reviewed links between the dyes and attention deficit disorder in a two-day meeting. The FDA has said it agrees with studies that say for "certain susceptible children," hyperactivity and other behavioral problems may be exacerbated by food dyes and other substances in food. But it has found no proven effect for most children.

The question for the panel and now for the FDA, which will review the panel's recommendations and decide whether to take action, is whether the potential effect on a possibly small percentage of children - it is unclear just how many - should lead to further regulation. The agency is not expected to diverge from the panel's advice.

Public health advocates and academics studying the issue agree that dyes do not appear to be the underlying cause of hyperactivity, but they say that the effects of certain dyes on some children is cause enough to ban the additives.

The FDA held the meeting in response to a 2008 petition filed by the advocacy group Center for Science in the Public Interest to ban Yellow 5, Red 40 and six other dyes. Michael Jacobson, the director of that group, said after the vote that he is disappointed that members of the panel were looking for perfect scientific evidence that the link exists. But he said he is pleased that the FDA is acknowledging that food coloring may affect hyperactivity in some children.

"It's a big change from a year ago," he said. "At least this hearing gave recognition to the fact there's a real issue here and I hope a lot of parents will buy foods without dyes."

Some companies have reduced the use of dyes in food sold in Europe due to public concerns about hyperactivity there while keeping them in U.S. foods. Jacobson said he hopes increased awareness will force some of those companies to use less dyes in the United States.

Parents who testified at the hearing said they are convinced there is a link between food coloring and their childrens' behavior. The mother of a 7-year-old boy who has struggled with hyperactivity showed off his improved report card and said eliminating food dyes from his diet was "life changing." She and other moms urged the panel to recommend warning labels.

"That warning would do enough so at least somebody may say `Gosh, that's the problem,'" said Renee Shutters, who came to the meeting from Jamestown, N. Y. She said ridding her son Trenton's diet of food colors helped make him a model student.

Representatives of food coloring makers and the food industry urged the agency to hold off, telling the panel Thursday that they don't believe the science is conclusive.

Most members of the panel agreed that the science isn't conclusive and said that more studies need to be done. All but one voted to recommend that the FDA further study the issue.

There was significant disagreement on the panel, though, over whether the FDA should include the warning labels.

Several members argued for a label that would let parents know there may be a connection between food coloring and attention deficit disorder since the FDA has acknowledged there is likely a link for some children.

"How many more years are going to pass before we have that kind of data?" said Lisa Lefferts, a consumer representative on the panel. "I don't think we need more study to take public health measures."

Wesley Burks, a professor of allergy and immunology at Duke University Medical Center, disagreed. He said a warning label could overblow the link between the dyes and attention deficit disorder.

"When you say 'some children,' that's not how a mother or father reads it," he said. "They read it as my child. So basically you are going to tell them that's the cause of it by labeling it."

Scientists and public advocates have debated the issue for more than 30 years as the use of dyes in food - especially foods marketed to - has risen steadily. Consumption of food coloring has doubled since 1990, according to some estimates.
