Liu Boren recalled that a mother came to see a doctor many years ago, and her mother had some problems such as memory loss, knee arthritis and hyperlipidemia. Originally, after seeing a doctor for the first time, according to the prescription of nutritional functional drugs, cholesterol dropped. Unexpectedly, total cholesterol rose to 230 mg/dl and low density cholesterol (LDL) reached 65,438+0.50 mg/dl.
My mother asked, "I have adjusted according to the doctor's instructions." How to adjust the worse? " At this time, the daughter who accompanied her mother to see a doctor asked Liu Boren, is this related to her mother's switch to coconut oil cooking in the last three months? "Because it is said on TV that coconut oil can reduce the risk of dementia and improve memory, my mother bought a lot of coconut oil on TV. Since then, she has cooked with coconut oil for three meals every day," said her daughter.
Long-term consumption of coconut oil will increase total cholesterol. Liu Boren said that coconut oil is a kind of vegetable oil rich in saturated fat. Some scholars believe that coconut oil can improve the cognitive function of the brain and prevent dementia. This is because coconut oil is rich in medium-chain fat (MCFA), which is easily absorbed, transformed into ketone bodies in the liver, and then enters brain cells to provide energy.
Although studies have shown that coconut oil intake will increase high-density cholesterol (HDL), Liu Boren said that according to the comprehensive analysis of 28 papers in New Zealand on 20 16, it was found that long-term use of coconut oil would increase total cholesterol and low-density cholesterol.
Coconut oil saturation is as high as 90%! In fact, for patients with high cholesterol, the White Paper on Dietary Guidelines 20 15-2020 issued by the United States emphasizes that patients with high cholesterol should reduce sugar, salt, saturated fat and trans fat, eat more vegetables, fruits and whole grains, and drink coffee in moderation.
Importantly, the guide cancels the * * * recommendation on cholesterol, but limits the intake of "saturated fat", that is, it must not exceed 65,438+00% of the total daily calories. Lard, butter and coconut oil are all oils with too much saturated fatty acids. The saturation of butter is 52%, lard is about 42% and coconut oil is as high as 90%!
"Coconut oil contains more saturated fat and lauric acid, which is a medium-chain fat with 65,438+02 carbons, which is why people have always emphasized the benefits of coconut oil, but don't forget that coconut oil also contains myristic acid, a long-chain fatty acid, which may increase total cholesterol and low-density cholesterol," Liu Boren pointed out.
Coconut oil is not everything. Therefore, Liu Boren suggested that the metabolism of coconut oil still depends on physique, dosage and frequency. "So can coconut oil with such high saturation really reduce the risk of dementia? Liu Boren believes that this may take longer to determine.
"I suggest never thinking that coconut oil is omnipotent. The smart rule of using oil is' rotation'. It is best to use more oils with high monounsaturated fatty acids such as olive oil and bitter tea oil, which may bring greater health benefits. " Liu Boren said that people with related diseases should not forget to draw blood to test their cholesterol every three months, because everyone's genes are different, so the catabolism of food ingredients may be very different.
