Among the 25 children enrolled, five had no food dye in their diet. Hyman found no correlation between artificial food dye consumption and repetitive behaviors or externalizing behaviors; however, she did find a correlation between yellow food dye consumption and sleep disturbances.
"While this is only a pilot study and needs to be interpreted conservatively, it merits a clinical trial to determine whether food dye might aggravate behaviors in children with ASD who are at greater risk for sleep problems than other children," Hyman said.
Another abstract authored by Hyman and colleagues was based on an analysis of the national dataset collected by the Autism Treatment Network on the use of complementary and alternative medicine in children with autism. It highlights the need for physicians to keep track of what other treatments parents may be using for their children. About 450 of the almost 2,500 children in the registry at the time the data were analysed, reported use of complementary therapies. About one-fifth of these 450 children were given a special diet at the time they entered the Autism Treatment Network. However, that rate changed throughout the first year of follow up.
