Does sugar really make kids hyper?

The party-time 'sugar high' is mostly happening in the adult's head, not the kid's body.

A meta-analysis pooled controlled double-blind trials where neither kids nor parents knew who got sugar and who got a placebo sweetener. Across the studies, sugar changed neither behavior nor attention. The myth survives because of expectation: in one experiment, mothers told their (sugar-free) son had just eaten sugar rated him as far more hyperactive and hovered over him more, even though he had nothing of the sort. The chaos people blame on cake is really excitement, late nights, and a roomful of friends.

At a birthday party the kids tear around like crazy and everyone blames the cake - but it's the games, the crowd and the late bedtime, not the sugar, doing the work.

Controlled tests find no sugar-driven hyperactivity; the 'sugar high' is an expectation, not a chemical effect.

Blaming sugar hides the real reasons kids get wound up (excitement, tiredness, crowds) and can make you misread a child's behavior the moment you hear the word 'sugar'.

Sugar high = a story the grown-ups tell, not a switch in the kid.
