Consuming food/drinks high in Sugar makes one hyperactive!

It's a common belief around parents worldwide in which many believe and claims that after their kids eat sugary food/drinks they become hyperactive. I'm no parent myself but after hearing that a lot from many people around me, I honestly thought it was true. 

After reading a lot of articles online regarding this one, it seems to be not true. There is just no scientific basis supporting this claim. There was even a study in which kids where given a sugary food/drink for a week but it didn't make them hyper.
