http://www.cbc.ca/consumer/story/2007/09/06/additives-lancet.htmlCertain common artificial food colourings and additives are fuelling hyperactivity in children, a British study has found.
The study in The Lancet medical journal, released late Wednesday, confirms a link long suspected by many parents between hyperactivity and food preservatives.
For the study, researchers at Southampton University studied 153 three-year-olds and 144 eight- to nine-year-olds, giving them fruit drinks with various levels of additives.
They found that children without a history of any hyperactive disorder showed varying degrees of hyperactivity after consuming the drinks.
Some became more boisterous, impulsive and had difficulty concentrating.
While some children in the test groups showed little or no response, the results were still significant enough for Britain's Food Standards Agency to issue a warning several hours after the study's release urging parents of hyperactive children to avoid foods with multiple additives.
Among the additives studied were:
E211, sodium benzoate, a preservative used to extend shelf-life of food and drinks.
E102, tartrazine, a yellow food dye used in ice cream, soft drinks and fish sticks.
E104, quinoline yellow, a yellow dye used in soft drinks, cosmetics and medications.
E110, sunset yellow, a dye used in yogurts and sweets.
E122, carmoisine, a coal tar derivative used in sweets and yogurts.
E129, allura red, a dye used in pop drinks and bubble gum.
According to Health Canada's website, all but one of the additives, carmoisine, are permitted for use in Canada.
The British government's Food Standards Agency stopped short of calling for a ban on the additives, although other countries have banned some of them.
Norway, for example, has banned all of the additives while the U.S. has banned quinoline and carmoisine.
