corn oil, sunflower oil, or olive oil is believed to have more healthy fat content than other types of oils or butter.
Unfortunately, when vegetable oils are used in temperature 180 Celsius or more, will very likely produce toxic aldehyde levels that endanger health.
Led by Martin Grootveld, a Professor of chemistry and chemical pathology of bioanalitikal at De Monfort University in the United Kingdom, the researchers did an experiment on corn oil and sunflower oil for frying potatoes and fish.
Found, frying with oil corn, coconut oil, olive oil, sunflower oil may release 200 times the toxic chemicals known as aldehydes that have been linked to cancer, heart disease, and dementia.
The research was quite surprising, due to the fact that other kinds of oil and butter contain more lots of saturated fat turns out to be far more secure to fry, rather than vegetable oils containing polyunsaturated fats.
In fact, health officials have encouraged the community to avoid butter and replace it with vegetable oil to reduce their fat intake.
"For decades, the authorities have warned us how bad effects of butter," says Grootveld told The Telegraph.
"But we have found that the butter is very good for frying in hot temperatures. Indeed there is nothing wrong with the statement if vegetable oil is expressed more healthy, but when you use it to fry for a long time, or bake it in a pan or in the oven, they will produce a chemical reaction that produces large amounts of toxic compounds. "
Vegetable oil will be fine as long as you don't cook it in a temperature too hot, such as frying, "says Grootveld in a press release.
"It's a fact that something that simple chemicals considered healthy for us could turn into something very unhealthy at a certain temperature.
