A new study has concluded that your child's school grades can be hampered by too much fast food.
The study, which involved 5,500 primary school children, found that pupils achieved lower scores in tests after eating takeaway meals such as burgers and chips more than three times a week, reports The Telegraph.
AdvertisementSome children's scores in literacy and numeracy dropped by up to 16 per cent compared to the average, the study claimed.
In the research, researchers from Vanderbilt University in Tennessee tracked the eating habits of children aged 10 and 11 - then compared it to performance in reading and maths tests.
They found just over half of pupils had eaten at fast food restaurants such as McDonald's up to three times in the last week.
n total, children scored between 58 and 181 points in the reading tests, gaining an average score of 141.5. But after taking other factors into account, pupils who ate fast food between four and six times a week scored almost seven points below average.
Children snacking once a day fell 16 points, while pupils indulging three times a day dropped by 19 points.
Similar trends were noted in maths.
Dr Kerri Tobin, who carried out the study, said it found "statistically significant relationships between higher than average consumption of fast food and lowered test scores".
"It is possible that the types of food served at fast food restaurants cause cognitive difficulties that result in lower test scores," she said.
