Is Poor diet liked to bad behaviour in Children?

The University of Southerm California fond a lack of zinc, iron, vitamin B and protein in the first three years caused bad behaviour later on.

I think there are risk factors which promote the bad behaviour in Children. For example, the parent ´s education or the culture where they usually live. If the father is agressive with his daugther or if the family always are sad.

It can cause hyperactivity disorders, but anti-social behaviour is more influenced perhaps by parentingand genetics and teen peer pressure in teenage groups.
