*drspouse "She gets hyper because you know she's has sugar and you think it makes her hyper."

@KarenTheGammonRemoaner, I'm afraid you owe @drspouse an apology. She is absolutely correct (and not patronising at all). There have been studies to prove it.
Sugar does not affect children's behaviour. The change in behaviour is a mix between a correlation between sugary foods and exciting events (e.g Christmas/Birthday parties/holidays/days out) and parental expectation of changed behaviour.

^Between them, the studies covered age ranges from two to thirty, and were well-designed though fairly small. All but one of the sixteen studies had fewer than fifty participants and one had just five. But the results of the meta-analysis were clear: sugar could not be shown to affect behaviour or cognitive performance.
Yet so many of us have watched children arrive at a party as reasonable, polite human beings, eat copious amounts of cakes and sweets and then transform into over-excited, over-energetic little devils – so how do we account for this? As the party goes on children play more games, and inevitably get more excited and then over-tired, when of course their behaviour deteriorates. We see kids get more unruly, notice how much sugary food they’ve had, and then assume there must be a link.
One study set out to test the expectation of parents who believed that sugar had a bad effect on their sons. In the experiment half the mothers were led to believe their sons were drinking something sugary. The other half were told the drinks really contained an artificial sweetner, not sugar. When the mothers were then asked to observe and rate their children’s behaviour, those who thought their sons had been consuming sugar said they were more hyperactive than the mothers who knew they had drank a placebo. But there was another twist to the study. While the mothers were observing their children, the researchers were observing them. They noticed that the mothers who thought their sons had drunk too much sugar not only criticised them more, they also stayed closer to them and watched them more. So the supposed sugar had not changed the boys’ behaviour, but their mothers’.^
