椰子油是否可以帮助预防机体心脑血管疾病的发生？

  关于椰子油是否对机体有特殊的益处至今尚无定论，因此并没有数据显示建议人们不要或者大量消耗椰子油。然而有些研究却建议人们尽量避免消耗椰子油，因为椰子油中不饱和脂肪酸含量非常高，不饱和脂肪酸会增加低密度脂蛋白胆固醇的水平，低密度脂蛋白和心脑血管疾病的发病风险增加直接相关。
  我们知道并不是所有的饱和性脂肪酸都有相同的效应，但是椰子油或许会含有一些不太可能会引起低密度脂蛋白水平升高的饱和性脂肪酸；这就好比是巧克力中含有的不饱和脂肪酸和硬脂酸一样，其引发低密度脂蛋白胆固醇水平升高的可能性较低；然而这些食物中的确含有不同的饱和脂肪酸的混合物，当前关于椰子油具有潜在效应的相关研究文献非常少。
  而对于不饱和脂肪酸有益作用的研究非常之多，很多研究都表明不饱和脂肪酸比饱和性脂肪酸具有更高的健康效应，因此如果你正在通过饮食调节自己的体重，那么就多消耗一些含有不饱和脂肪酸的食物。
  研究者表示，个体的总脂肪摄入要适度，大约占每日卡路里摄入的25%至35%；利用含有不饱和脂肪酸，比如大豆油、介花油及玉米油的食物作为日常饮食的主要成分对机体或许是最好的，有研究就发现，不饱和脂肪酸的摄入对于预防个体的心脑血管疾病的发生具有明显的效应。（转化医学网360zhyx.com）

There is no consistent body of data that I am aware of to indicate that coconut oil has documented specific beneficial effects; hence, there is no data that I'm aware of to suggest people should go out of their way to consume coconut oil.
There is some data, however, to suggest it is best to avoid consuming coconut oil because it is relatively high in saturated fatty acids. Saturated fatty acids raise LDL cholesterol, which is associated with increased risk of cardiovascular disease.
We do know that not all saturated fatty acids have the same effect; and yes, coconut oil may have some saturated fatty acids that are less likely than others to raise LDL cholesterol, the same way that chocolate contains a saturated fatty acid, stearic acid, that is less likely than others to raise LDL cholesterol. However, these foods do come with a mixture of saturated fatty acids. Currently, the evidence for potential beneficial effects of coconut oil is very limited.
We do know that the preponderance of the evidence indicates that consuming unsaturated fat results in better health outcomes than eating saturated fat. So, if you are going to adjust fat in your diet, replace saturated with unsaturated fat. The total fat intake should be moderate, between 25 and 35 percent of your daily calorie intake. Using unsaturated fats such as soybean oil, canola oil and corn oil when preparing foods and making salad dressings is a good idea. Fat is good, fat is important, and unsaturated fat has health benefits.
