Coconut Oil Raises Total Cholesterol, and Bad LDL Cholesterol | 椰子油增加總膽固醇、和有害的低密度膽固醇

Jkzx.com notes:  Any cooking “healthy” oil can pose a risk.  Many vegetable oils like soy oil, canola oil, corn oil etc. which are rich in polyunsaturated fatty acids, can be converted into trans fat during the cooking.  Polyunsaturated fatty acids are chemically highly unstable and they are easily degraded to become harmful trans fat and other chemicals.   Trans fat is known to be harmful to cardiovascular health.  In comparison, saturated fat is stable and cannot become trans fat.  Of course, excess saturated oil is not as healthy either.  

Coconut oil has been touted as a healthy oil for the past 10 years. To push the marketing of coconut oil, celebrity endorsements claim that coconut oil helps eliminate belly fat, suppress appetite, boost the immune system, prevent heart disease, and more. Coconut oil has gained popularity despite scientific evidence that consuming it has no cardiometabolic benefits. A survey found that 72 percent of Americans believe coconut oil is “healthy” and is popular on ketogenic and paleo diets. However, most nutrition experts disagree with this view. Coconut oil is 92% saturated fat. A diet high in saturated fat increases total cholesterol and bad LDL cholesterol, increasing the risk of cardiovascular disease. For this reason, the American Heart Association recommends limiting your daily intake of saturated fat to 5 to 6 percent of your daily calories. #coconut oil #cholesterol #heart disease  (Translation from the following by Dr. Zhang)

Jkzx.com 指出：任何食用油都可能帶來風險。 許多植物油如豆油、菜籽油、玉米油等富含多不飽和脂肪酸，在烹調過程中會轉化為反式脂肪。 多不飽和脂肪酸的化學性質極不穩定，很容易降解成有害的反式脂肪和其他化學物質。 眾所周知，反式脂肪對心血管健康有害。 事實上，飽和脂肪是穩定的，不會變成反式脂肪。 當然，過量的飽和油也不健康。

在過去的 10 年裡，椰子油一直被宣傳為一種健康油。為了推動椰子油的營銷，名人代言 聲稱椰子油有助於消除腹部脂肪、抑制食慾、增強免疫系統、預防心臟病等。儘管，科學證據表明，吃椰子油對心臟代謝沒有好處，椰子油還是大受歡迎。一項調查發現，72% 的美國人認為椰子油是“健康”的，在生酮飲食和舊石器飲食中很受歡迎。然而，大部分的營養學專家不同意這一觀點。 椰子油中有 92% 是飽和脂肪。富含飽和脂肪的飲食會增加總膽固醇和有害的低密度脂蛋白膽固醇，增加心血管疾病的風險。因此，美國心臟協會建議將每天吃飽和脂肪的量要控制在每天卡路里的 5% 至 6%。#椰子油 #膽固醇 #心臟病 (by Dr. Zhang)
