Theories of what causes ADHD seem to grow with each day. There are a variety of biological and environmental theories that tend to get most of the press and truthfully have the most credibility. However, nutrition research has made a link between some food additives and ADHD. Specifically, some additives found in popular soft drinks may play a role.
One of the additives, sodium benzoate, has been linked to cell damage in a previous study, and to an increased for cancer. Sodium benzoate is found in Coca-Cola, Pepsi Max and Diet Pepsi, and in many fruit drinks.
Other additives assessed in the study include a number of colorings – sunset yellow (E110), found in fruity drinks; carmoisine (E122), a red coloring often added to jams; ponceau 4R (E124), a red food coloring; tartrazine (E102), found in lollipops and carbonated drinks; quinoline yellow (E104), a food coloring; and allura red AC (E129), and orange-red food dye.
The researchers cautioned against belief that additives alone could cause ADHD, but noted that this finding was important. I would also encourage come caution against viewing that as a large factor, but hopefully it can be another reason for parents to limit unhealthy foods from their child’s diet.
