Deep-frying at high temperatures has been linked to a number of metabolic disorders. The rats that consumed reheated sesame or sunflower oil suffered from oxidative stress and increased inflammation in the liver.
They also had significant damage to the colon and associated changes in endotoxins. This, in turn, resulted in neurodegeneration, which was seen in the histology of the brains of the Rats that consumed the reheated oil, as well as their offspring."To the best of our knowledge, we are the first to report long-term damage," said the researcher.
