PERTH, Australia, July 31 (UPI) — Australian researchers linked the “Western-style” diet — processed, fried and refined foods — and attention-deficit hyperactivity disorder.
Researchers at Perth’s Telethon Institute for Child Health Research say a diet high in the Western pattern of foods high in fat, refined sugar and sodium — is associated with more than double the risk of having an ADHD diagnosis compared with a diet low in the Western pattern.
The study, published in the International Journal of Attention Disorders, suggests teens eating what the researchers characterized as a healthy diet — lots of fresh fruit and vegetables, whole grains and fish and high levels of omega-3 fatty acids, folate and fiber — provides mental health benefits and optimal brain function.
However, the researchers point out it is not clear if the healthy diet provides essential micronutrients needed for brain function — particularly attention and concentration — or if other substances in the Western diet — colors, flavors and other additives — may lead to an increase in ADHD symptoms. In addition, impulsivity — a characteristic of ADHD — leads to poor dietary choices such as quick snacks when hungry.
“We cannot be sure whether a poor diet leads to ADHD or whether ADHD leads to poor dietary choices and cravings,” study leader Wendy Oddy said in a statement.
Oddy and colleagues examined the dietary patterns of 1,800 adolescents of whom 115 had been diagnosed with ADHD by age 14.
