Although many parents know the health risks of feeding their children junk food at a high rate, a new study is suggesting it could also lower their overall IQ scores.

The Telegraph reports that a study conducted by researchers from the University of Bristol found that children who were fed a diet of pasta, salads and fruit were more likely to have a higher IQ than those who had diets consisting of high instances of fats, sugars and other processed foods.

"This suggests that any cognitive and behavioral effects relating to eating habits in early childhood may well persist into later childhood, despite any subsequent changes - including improvements - to dietary intake," Dr. Kate Northstone, the study's author, told the news provider.

The study reports that for every one point increase in a dietary pattern score indicated a 1.67 point fall in a child's IQ score, which was an indication that parents may want to consider instilling a healthier diet in their children in order to boost brain function.

There are certain nutrients that individuals can consume to help boost brain power, such as ginkgo biloba.
