Researchers have stated that diet contributes to ADHD in kids. For concluding this, researchers in Perth, Australia, assessed about 1800 adolescents for their eating pattern. They made an attempt to record if they developed attention deficit hyperactivity disorder.

The diets were divided into two, namely healthy and Western patterns.

Kids who had fresh fruits, vegetables, fibre and fish were put in the healthy diet group and kids who had more of easy food that was processed, salty, fried etc were included in Western diet group.

Wendy Oddy, leader of nutrition studies at the Telethon Institute for Child Health Research in Perth said, "We found a diet high in the Western pattern of foods was associated with more than double the risk of having an ADHD diagnosis compared with a diet low in the Western pattern."

It was stated that the essential nutrients needed for brain to function, concentrate properly was not present in Western diet and it also contain more additives, flavours and colours that are linked to ADHD.

Dr. Oddy said it was not confirmed that was it the diet that caused ADHD or was it the ADHD that made one select a poorer diet.
