A man in his 50s, who was very frugal by nature and often reused cooking oil at home, was diagnosed with liver cancer a few years ago.
Rats that consumed deep-fried sesame oil or sunflower oil showed oxidative stress and inflammation in the liver, and their colons were also significantly damaged, leading to the production of toxins such as endotoxins and lipopolysaccharides. Studies have found that this shows that recycled oil can cause abnormal lipid metabolism in rats livers and block the important omega-3 fatty acid DHA from the liver to the brain. "
Frequent consumption of fried foods can interfere with the communication axis between the liver, intestines and brain, and may increase neurodegeneration in the long term. [;-)]
