...study, led by Jim Stevenson, a professor of psychology at England's University of Southampton, involved about 300 children in two age groups: 3-year-olds and 8- and 9-year-olds. Over three one-week periods, the children were randomly assigned to consume one of three fruit drinks daily: one contained the amount of dye and sodium benzoate typically found in a British child's diet, a second had a lower concentration of additives, and a third was additive-free. The children spent a week drinking each of the three mixtures, which looked and tasted alike. During each seven...
...Stevenson found that children in both age groups were significantly more hyperactive when drinking the beverage with higher levels of additives. Three-year-olds had a bigger response than the older kids did to the drink with the lower dose of additives, which had about the same amount of food coloring as in two 2-oz. (57 g) bags of candy. But even within each age group, some children responded strongly and others not at all. Stevenson's team is looking at how genetic differences may explain the range of sensitivity. One of his colleagues believes that the additives...

...Stevenson found that children in both age groups were significantly more hyperactive when drinking the stuff containing additives. Three-year-olds had a bigger response than the older kids to the lower dose of additives - roughly the same amount of food coloring as in two 2-oz. bags of candy. And, there were big individual differences in sensitivity. While the effects were not nearly so great as to cause full-blown ADHD, Stevenson nonetheless warns that "these adverse effects could affect the child's ability to benefit from the experience of school...
...Stevenson is heavily outweighed and at least a foot shorter than both men, but stands his ground. "You've got to calm down," he shouts at the man at least five times. Later he says: "You can't back down on these guys. It just gets worse. I would have pepper-sprayed the big guy." Dealing with the incident has taken five patrol cars and a lock-up van; the effort brings calm to the street, but the violence continues to spread across the suburb like a brush fire. Within minutes, reports of three more stabbings in the same district...
