Is there a link between food and hyperactivity in children?

Linked in some cases. Like so many brain/behavior disorder, adhd is probably not one, "homogenous" condition, but reflects multiple causations, brain mechanisms and treatments, even tho they share similarities of course. Diet turns out to be a useful key for some children, but not a majority in controlled trials. When it works, it is worth the effort. The feingold diet is the most famous, indicting food dyes, sugar, .
