Food Additives Raise Hyperactivity

Common food additives and colorings can increase hyperactive behavior in a broad range of children. It was the first time researchers conclusively and scientifically confirmed a link that had long been suspected by many parents. Numerous support groups for attention deficit hyperactivity disorder have for years recommended removing such ingredients from diets, although experts have continued to debate the evidence. But the new, carefully controlled study shows that some artificial additives increase hyperactivity and decrease attention span in a wide range of children, not just those for whom overactivity has been diagnosed as a learning problem. The new research was financed by Britain’s Food Standards Agency and published online by the British medical journal The Lancet.

“A mix of additives commonly found in children’s foods increases the mean level of hyperactivity,” wrote the researchers, led by Jim Stevenson, a professor of psychology at the University of Southampton. “The finding lends strong support for the case that food additives exacerbate hyperactive behaviors (inattention, impulsivity and overactivity) at least into middle childhood.”

The Lancet study focused on a variety of food colorings and on sodium benzoate, a common preservative. In the six-week trial, researchers gave a randomly selected group of several hundred 3-year-olds and of 8- and 9-year-olds drinks with additives — colors and sodium benzoate — that mimicked the mix in children’s drinks that are commercially available. The dose of additives consumed was equivalent to that in one or two servings of candy a day, the researchers said. Their diet was otherwise controlled to avoid other sources of the additives. A control group was given an additive-free placebo drink that looked and tasted the same. All of the children were evaluated for inattention and hyperactivity by parents, teachers (for school-age children) and through a computer test. Neither the researchers nor the subject knew which drink any of the children had consumed. The researchers discovered that children in both age groups were significantly more hyperactive and that they had shorter attention spans if they had consumed the drink containing the additives.

The study’s authors noted that other research suggested that the hyperactivity could increase in as little as an hour after artificial additives were consumed.

Bonnie - another eureka moment! I have been saying since I started practicing that artificial colors and flavors affected child behavior. I didn't need a study to tell me that. It was apparent in my clients, the schools in taught in schools, and my own daughter, who was one of the reasons I got into the field. However, for the mainstream public and medical community, this should come as a shocker.
