The belief that sugar causes hyperactivity in children is not supported by scientific evidence. Numerous controlled studies conducted over several decades have consistently found no direct causal link between sugar consumption and hyperactive behavior. A comprehensive meta-analysis published in the Journal of the American Medical Association examined 23 different studies and concluded that sugar does not affect the behavior or cognitive performance of children, even in studies that specifically looked at children described as "sugar-sensitive" by their parents.

The most rigorous research involved double-blind trials where neither parents nor children knew whether they had consumed sugar or a placebo sweetener. In these studies, children's behavior showed no significant differences between the two groups. Interestingly, when parents believed their children had consumed sugar (even when they hadn't), they rated their children's behavior as more hyperactive and were observed to interact with them more critically, suggesting that expectations play a powerful role in perception.

This misconception likely persists because sugary foods are often consumed at exciting events like birthday parties, holidays, and celebrations where children naturally exhibit more energetic behavior due to the stimulating environment rather than the sugar itself. Additionally, the temporary energy boost from quick-digesting carbohydrates may be misinterpreted as hyperactivity. While excessive sugar consumption does pose legitimate health concerns such as tooth decay and obesity, behavioral hyperactivity is not among them according to current scientific consensus.
