Eating onion rings and french fries could raise your risk of dementia, a new study on the harms of deep-fat frying suggests.
Researchers looked at the effect of food made using large amounts of cooking oil that's reused — which is often the case in restaurants.
They found that old oil can contain brain-damaging impurities, which ultimately end up in the food.
Rats fed a diet high in reused oils showed more signs of bodily inflammation, said to damage blood vessels and speed up cognitive decline.
Researchers also detected more signs of brain damage in rats fed diets high in reheated oils, compared to a control group.
The scientists, from the University of Chicago, said: 'Deep-frying at high temperatures has been linked with several metabolic disorders.
Researchers warned foods fried in reused cooking oil could cause more neural decline
'To our knowledge, we are the first to report that long-term deep fried oil supplementation increases neurodegeneration.'
The results were presented at the annual meeting of the American Society for Biochemistry and Molecular Biology in San Antonio, Texas.
