A study concluded in 2004 suggests that children fed a poor diet are more likely to be irritable, swear, argue, and generally develop an anti-social attitude.

Professor Adrian Raine from the University of Southern California (USC) co-authored a study based on the development of more than 1000 children from Mauritius, an island in the Indian Ocean just off the coast of South Africa.

The researchers analysed data over a 14-year-plus period which included factors such as social background, education and health, and they concluded that the more under-nourished the children, the greater the risk of anti-social behavior in later years.

Therefore, Professor Raine pointed out that parents could help prevent their children developing anti-social and aggressive bevavior by ensuring they receive a nutritional diet.
