Can food dye cause hyperactivity?
A study by the United Kingdom’s Food Standards Agency in 2007 showed that the
consumption of foods containing dyes could increase hyperactive behavior in
children. In the study of 3-, 8- and 9-year-olds, children were given three
different types of beverages to drink. Then their behavior was evaluated by
teachers and parents.
One of the drink mixtures contained artificial food colorings, including:
- Sunset yellow (E110)
- Carmoisine (E122)
- Tartrazine (E102)
- Ponceau 4R (E124)
It also contained the preservative sodium
benzoate. The second drink mixture included:
- Quinoline yellow (E104)
- Allura red (E129)
- Sunset yellow
- Carmoisine
It also had sodium benzoate. The third drink mixture was a placebo and
contained no additives.
The researchers found that hyperactive behavior by the 8- and 9-year-olds
increased with both the mixtures containing artificial coloring additives. The
hyperactive behavior of 3-year-olds increased with the first beverage but not
necessarily with the second. They concluded that the results show an adverse
effect on behavior after consumption of the food dyes.
