Harmful effects of cooking oil on the body

Experts warn that eating processed food from recycled oil will accumulate toxic substances and die slowly with the risk of cancer, obesity, cardiovascular .

>>>Products from waste cooking oil appear in Vietnam

14 products made from sewage oil in scandal in Taiwan are exported to 12 countries and territories, including Vietnam. Two products warned by Taiwanese are present in Vietnam market are cucumber mixed with canned pork and canned meat sauce. The authorities have not found products on the market and are in the process of checking.

According to Dr. Nguyen Duy Thinh, lecturer of the Institute of Biotechnology and Food, Hanoi University of Science and Technology, eating foods prepared from sewer oil, the human body will be poisoned gradually.

Dr. Thinh explained, dirty cooking oil is not food oil and is not allowed to use food processing. It was picked up from waste water, mixed in sewage and lots of garbage, scum. Initially, this dirty oil was picked up for the purpose of cleaning the environment because they often float to the surface of the waste water so that the surface of the waste water is not ventilated, microorganisms cannot survive, difficult to handle.

After salvage, the oil is made in, processed further but it is still very dirty because it cannot filter all impurities. This oil was originally used as an ingredient in industrial products such as ceramics (lubrication of package surfaces, fired bricks .), or very small parts of animal feed.If humans eat directly this oil will be very dangerous . It is a solvent that dissolves hazardous substances in sewage, sewage (from cleaning chemicals to heavy metal residues, dyes, grease for lubricating machinery .). When consumed, the human body will accumulate not knowing how many of these toxins can cause dangerous diseases.

"A piece of meat fell to the ground, not to mention falling into the sewer, no one picked it up. The dish prepared with dirty oil should not be eaten. This oil must be banned for human use. use, must be severely dealt with by law " , Dr. Thinh expressed.

Mr. Thinh said, no need to analyze much can also see how dirty cooking oil contains many toxins. People who consume it may not be affected immediately, because each time they eat not much, it will definitely accumulate and cause poisoning gradually."The death-causing cause is far more dangerous than those that can kill people right away because users are caught off guard by it, not knowing the hidden risks inside , " the food technology expert said. strong.

Associate Professor Tran Hong Con, Department of Chemistry, University of Natural Sciences, Hanoi National University said, on the principle of cooking oil is used only once . Used oil is not allowed to be used for food processing. Normally, grease is discharged from the kitchen or collected from a sewer in a restaurant, the hotel is only used for processing into other substances such as dry alcohol, lubricating oil .

'The fried cooking oil has been cooked many times, plus the recycling at high temperature so the chemical composition is changed, decomposing to many health-damaging substances, especially trans-fat. . This type of fat enters the body, increasing the risk of cancer, obesity, cardiovascular disease, etc. , 'said the associate professor.

In addition, the waste oil source discharged into drains to be reclaimed will not avoid the risk of toxic impurities, heavy metals from outside the environment and the recycling process always comes with the use of additional chemicals. Support should contain a myriad of toxic health risks. If grease and raw materials used to produce fats and oils are not carefully stored, mold and mildew are at risk of containing aflatoxin compounds, a poison that is highly likely to cause cancer.

Concerning the oil scandal from the sewage waste that has shaken Taiwan over the past few days, the South China Morning Post said, not only is poor sanitation, oil recycled from the waste oil of restaurants, waste from cattle slaughterhouses, contaminated materials, overdue leather . also contain carcinogens such as benzopyrene and aflatoxin.

According to a food technology expert in Ho Chi Minh City, aflatoxin is produced from mold species of the genus Aspergillus, growing on cereal species. Aflatoxins cause great harms and extremely serious consequences for people and animals such as damage to liver cells, kidneys also swell to make the excretion of toxins from the body go away. Difficulty.

This toxin also reduces the resistance of animals, inhibits the antibody production system, erodes the lining of the gastrointestinal tract because the cell layer of the mucous membranes dies and dries, impeding the transport. transfer food in the gastrointestinal tract .
