How true is it that sugar makes children hyperactive?

Nothing would make a parent happier than finding the cause of hyperactive behavior. But alas, the sugar-hyperactivity myth has been debunked. There have been numerous studies looking at the role of dietary sugar in children and there is no evidence that it makes kids hyper. They tested the effects of natural sugars such as those found in fruit and added sugars like those found in candy bars. Interestingly enough, parents perceived their child as hyperactive when they were told they had consumed a sweetened soft drink, when in fact it was sugar-free.
