Scientists from the University of New South Wales have found a conclusion of an experiment, which they already trial to the rats that were fed foods rich in fat and sugar on a regular basis. After a week of the trial period, the results were very surprising; the rats did actually experience symptoms of memory disorders.
Memory disorders also occur in rats that were fed foods rich in sugar only, and it has been confirmed by previous studies*, with regard to the adverse effect of sugary foods against cognitive development.
In subsequent trials, scientists see memory disorders in rats are getting worse where the rats actually has does not recognize certain places, whereas the places just shifted a bit from where it was. The surprise is a disorder of the brain memory happened so quickly after eating junk foods.
“What is so surprising about this research is the speed with which the deterioration of the cognition occurred,” says Professor Morris, from the School of Medical Sciences. “Our preliminary data also suggests that the damage is not reversed when the rats are switched back to a healthy diet, which is very concerning.”**
It proves that memory impairment in rats that look increasingly worrisome after consuming junk food than before they didn’t. The study describes the presence of inflammation in the hippocampus, which is the main component in the brain and associated with spatial memory.
“We know that obesity causes inflammation in the body, but we didn’t realise until recently that it also causes changes in the brain,” says one of the authors Professor Margaret Morris from UNSW Medicine.**
The study published in the Brain journal, Behavior, and Immunity.
