British scientists: Vegetable oil is more carcinogenic than lard

Heating ordinary vegetable oils such as corn oil and sunflower oil can produce a large number of aldehyde compounds, which may lead to cancer, heart disease and dementia.

Cooking fish and chips with vegetable oil, carcinogenic aldehyde content exceeds WHO's health standards by 100 to 200 times

Vegetable oil produces Ω-6 fatty acids, which can reduce Ω-3 fatty acids in the brain, thereby causing people to develop mental health diseases, aphasia, etc.

Some people may think that cooking with vegetable oil is healthier, but a British study found that this may not be the case.At high temperatures, some vegetable oils may produce more toxic carcinogens.

According to the British Daily Telegraph on November 7, British scientists said cooking with vegetable oils such as corn oil or sunflower seed oil may lead to a variety of diseases, including cancer.Scientists recommend using olive oil, coconut oil, butter and even lard instead of ordinary vegetable oil.

>>Coconut oil produces the healthiest aldehyde carcinogens

Studies have found that ordinary vegetable oils produce a large number of aldehyde compounds when cooking when heated;Aldehyde compounds may lead to various diseases such as cancer, heart disease and dementia.

Groot Wild, a professor of bioanalytical chemistry at the University of Demontford in the UK, said that the content of carcinogenic aldehydes in a regular fried fish and chips cooked from vegetable oils in the UK is 100 to 200 times that of the World Health Organization's health standards.Relatively speaking, if you switch to butter, olive oil, lard or coconut oil, the aldehyde substances produced will be greatly reduced;Among them, coconut oil is the healthiest and produces the least aldehyde carcinogens.

The research team found that olive oil, corn oil and sunflower seed oil, whether heated for 10 minutes, 20 minutes or 30 minutes, produce more aldehyde compounds than butter, only coconut oil is less than butter. No matter what kind of oil, the aldehyde compounds produced by heating with food are more than when heated alone.

Through a series of research and experiments, Grootweld believes that vegetable oils are harmful to health.He said: “For decades, officials have warned us about how bad butter and lard are.However, we found that when it comes to frying and stir-frying, butter is very good, and so is lard.People have been saying how healthy the polyunsaturated substances in corn and sunflower oil are.But when you use them heavily in a wok and oven, they will undergo a series of complex chemical reactions, accumulating a large number of toxic chemicals.”

>>British scientists: no longer eat sunflower oil and corn oil

In addition, Stein, a professor of neuroscience at Oxford University, also found through research that vegetable oils can produce fatty acids, which is equivalent to the threat to the earth caused by climate change.Vegetable oil can produce Ω-6 fatty acids, which replace Ω-3 fatty acids in the brain, resulting in a significant reduction in the latter content.

"If you eat too much corn oil or sunflower oil, your brain absorbs too much 'Ω-6', thus effectively driving away 'Ω-3'," Stan said.I believe that the lack of 'Ω-3' can cause a lot of trouble, such as mental health illness or aphasia."Stan said he no longer eats sunflower oil and corn oil, but has all been replaced with olive oil and butter.

Grootweld suggested that people should try to avoid vegetable oils rich in polyunsaturated substances and eat less if they can.The World Health Organization has previously stated that eating red meat and bacon will increase the risk of cancer.comprehensive
