Fried food not only provides us with calories

The American Society for Biochemistry and Molecular Biology published the announcement of a new study that showed that oil reused for frying leads to the development of dementia (neurodegeneration). In addition, the harmful effect of overcooked oil is transmitted to descendants. They have not yet tested it on people, but on laboratory rats, but this also leaves a sad lesson for people, says Zukhra Pavlova, endocrinologist, Doctor of Medical Sciences, senior researcher at the Faculty of Fundamental Medicine of Moscow State University . she, she told KP.RU.
Are French fries, onion rings and chicken nuggets killing our brains?
Through a bidirectional liver-gut-brain network, say the study authors.
Heated sesame and sunflower oil given to rats for 30 days caused inflammation in the liver, damage to the colon, and reduced transmission of the omega-3 fatty acid DHA, important for the brain. Furthermore, both in the first generation and in the second, in the offspring. Neurodegeneration, the degradation and death of brain neurons, characteristic of people with dementia, Alzheimer’s and Parkinson’s, developed here.
“The main problem with frying is that this cooking method generates advanced glycation end products,” says Zukhra Pavlova. – This is the structure of a modified protein. Protein molecules interact with carbohydrate molecules and “cross-links” are obtained: the configuration of the protein changes, its properties change.
This reaction leads to neurodegeneration, a disruption of impulses passing through the brain.
And not only to alterations in the functioning of the brain: breakdowns also occur in the vessels of the liver, heart and kidneys.
The end products of glycation modify both the functioning of the brain and its activity, so when frying food we are really “digging our own grave”, and at an accelerated pace, says our expert.
If the oil is also fried several times, these harmful products become much more numerous.
Why does this affect the offspring?
We still have to figure this out, says the doctor. The changes don’t happen quickly, but apparently something influences the genome of the rats, and probably the people who eat this way, so actively that the DNA molecule changes.
By frying food, we are digging our own grave.

WHAT ELSE IS HARMFUL TO FRY?
Fried food actually does more than just add calories to us. Repeated use of the same oil for frying, which we often do at home and in fast food restaurants, removes beneficial substances from food, including antioxidants that protect cells from damage caused by stress and as a consequence of our bad habits. .
The oil that is reused also contains trans fats, which store toxins that are harmful to the heart and metabolism; acrylamide, which also reduces the ability to conceive; Oxidation products that wear down all the tissues of the body.
