Junk food impacts memory in days: study

Hard as it may be to swallow, it's no secret that a diet of cakes, sweet treats and burgers will impact the waistline.

But research from the University of NSW suggests an unhealthy diet can also take a toll on the memory.

Research released on Tuesday and published in the Brain, Behaviour and Immunity journal showed rats on a diet high in fat and sugar had impaired memories after almost a week.

"Interestingly, our rats were not obese and these changes emerged at day five," research co-author Professor Margaret Morris told AAP.

"So you don't have to be obese, you just have to eat poorly."

Prof Morris noted there was pressure in society to be thin yet not all thin people kept healthy diets.

Researchers placed groups of rats on different diets, including low-fat food with sugar water, low-fat food with water, cafeteria food with water and cafeteria food with sugar water.

All rats on the diets with high sugar and fat, including cake, chips and biscuits, showed deficits, Prof Morris said.
