Sugar doesn't make kids hyper. The belief does.

Every parent knows the birthday-cake tornado: minutes after the sweets, the kid bounces off walls. It feels causal, so scientists blind-tested it. Identical treats, half sugar, half sweetener; kids, parents, testers all in the dark.
The 1995 JAMA meta-analysis pooled 23 such trials. Sugar changed neither behavior nor thinking in children. The authors' caveat: a small effect in some kids can't be ruled out.
The twist: in 1994, 35 boys whose parents swore they were sugar-sensitive all got a placebo. Half the mothers were told their son had gotten a large dose of sugar. Those mothers rated their boys more hyperactive and hovered closer. Identical treats. The label did the work.
A 2026 systematic review does link sugary drinks with more ADHD symptoms, but those studies are mostly weak, and that's a different question: long-term diet, not cake causing a tornado.
Sugar is still empty calories and cavity fuel. But the party is the tornado, not the frosting.
