When I was younger, I was told not to have too much sugar (candy, soda, ice cream - anything sweet really) because I would get too hyper and I wouldn't be able to sleep at night. I never really felt very affected by sugar, but I have seen people that I do think get affected by sugar.

**Does sugar cause [hyperactivity][1] in children? If so, how much is too much?**
