A recent study has found that some artificial food dyes and preservatives may be linked to increased hyperactivity in children. The study used drink mixtures containing the preservative sodium benzoate, along with common food dyes. Children fed those mixtures had increased hyperactivity scores compared with those who were given a placebo drink. The study looked at a group of three-year olds and a group of eight and nine-year olds. Increased hyperactivity was found in both groups, when given the mixture of preservative and food dyes. According to the investigation, behavioral effects of food additives can occur in as little as one hour. The results of the study were reported online in The Lancet. The study was a randomized, double-blind, placebo-controlled, crossover trial, and its results lend support to the argument that food additives exacerbate children’s hyperactive behavior.
